Promoting Welfare Biology as the Study of Wild Animal Suffering
 
24:14
Animals in the wild often suffer tremendously, from starvation, exposure to the elements, and preventable disease. Rabies vaccination programs have substantially helped certain wild animals, but those programs were designed mostly to protect humans and our pets. What if we went a step further and tried to help wild animals for their own sake? In this talk from EA Global 2018: London, Oscar Horta argues that we might be able to make a truly huge impact through the study of welfare biology.

10 Most Shocking Real Mutations In Animals
 
04:44
Top 10 scariest animal mutations that are from your nightmares Subscribe to our channel: http://goo.gl/9CwQhg For copyright matters please contact us at: [email protected] Other Videos You Might Like: 10 REAL Abnormally Large Creatures You Won't Believe! https://youtu.be/QWA2r8zMFl4 10 Teens You Won't Believe Actually Exist! https://youtu.be/tEoVAuFmZhk Description: The animal kingdom is a vast variety of different animals. From cats to reptiles to sea creatures, there is so much to appreciate and admire from animals that we seldom think about the human impact on their survival. The list of endangered species is growing by the day, and we are losing some of the most beautiful animals that have ever existed due to overhunting, drought, manipulating nature, and uses of chemicals. When exposed, several animals today have been born with genetic mutations that cause deformities and physical mutations that defy the laws of biology and physics. If there are no chemicals or nuclear plants present, there have been cases of man trying to cross breed different species for the purposes of creating new animals. Dogs are notorious victims of this practice, which is why we now have “designer” dogs that were never meant to exists. Sometimes, mutations can go nuts to the point where what is born is completely creepy and sends shivers up all of our spines. We feel both horror and pity towards the animal, and in most cases, the animal isn’t able to survive with the mutations and ends up having to be put out of its misery. While some of the stories can be tragic, there are also survival stories that are both incredible and inspiring, even if the animal still manages to creep us out and make us really uncomfortable. Here are stories of creepy mutated animals that you won’t believe are real and not photoshopped.

The Amazing World Seen Through A Microscope
 
03:13
Outstanding microscopic images you've probably never seen before. Subscribe to our channel: http://goo.gl/9CwQhg ----------------------------------------------------------------------------------------- Description: There is a fascinating world all around us. From trees, humans, animals, houses, wildlife, and more, there is nothing around us that isn’t short of amazing. Even with the ocean, there is a world that we have yet been able to capture fully, as the depths of the ocean goes beyond what we can explore as humans at the moment. But there is yet, another world that have just started to discover. If you’ve ever been a fan of Dr. Seuss’ “Horton Hears a Who”, then you’ll be delighted to know that there is a whole other world that is so tiny that we cannot see with our naked eye. It’s a real life Whoville as there are creatures that are microscopic and hanging out in our clothes, water, body parts, and more. Before you get the heebie jeebies or want to put yourself through a cleansing shower, you should be relieved to know that most of these organisms are friendly and are here to help you. For example, there are tiny little mites that hang out on our eyelashes. They help shed dead skin off our our eyes and keeps our eyes fresh and clean. Also, if you have ever hung out in the ocean, you might be tickled to learn that there are thousands of tiny creatures in every drop of ocean water. But there is more to this tiny world than just the organisms, the tiny objects that we use each day can be beautiful and emulate what we see in our normal-sized life. For example, a piece of cracked steel is just as majestic and beautiful as the Grand Canyon. If you have ever had issues threading a needle, you’ll be relieved to know that it’s most likely that the thread is too much of a mess to go through the eye of the needle smoothly. Also, all of us are familiar with dust, and how inconvenient it is with having to clean it up on a near daily basis. But dust can be some of the most interesting things to look at if you put it under a microscope. From skin dander, pet dander, and even the body parts of insects, there is a whole other diverse world with a dust speck. Speaking of another world, if you ever put a marijuana leaf underneath a microscope, you’ll find a psychedelic and colorful world on the leaves, which is rather interesting given the affects that the THC-fused plant has on our brains. Essentially, don’t judge a book by its cover. There is so much out there when it comes to our world that isn’t limited to what we can perceive. If you want to feel large, then grab yourself a microscope and get a better perception of what is all around us. It should not only be empowering, but also humbling at the same time, as we don’t know everything there is in the world. But we also have such a wondrous world that has yet to be discovered and our adventure in doing so is far from over. ----------------------------------------------------------------------------------------- Our Social Media: Facebook: https://www.facebook.com/TheRichest.org Twitter: https://twitter.com/TheRichest_Com Instagram: http://instagram.com/therichest ----------------------------------------------------------------------------------------- Featuring: A MAGGOT CUT BEARD HAIR CRACKED STEEL A GECKO TOE EYELASHES EYELASH MITE THE MARINE WORM NEEDLE AND THREAD HOUSEHOLD DUST MARIJUANA THE HUMAN EYE SEAWATER ----------------------------------------------------------------------------------------- For more videos and articles visit: http://www.therichest.com/

How Does Cooperation Evolve?
 
03:49
If you find this animation helpful, consider supporting our work at http://statedclearly.com/contribute/ Lichen is a combination of algae and fungus (and in many cases, a third species of yeast) living together. This relationship allows the intertwined organisms to survive in locations they could never live on their own. If evolution is all about "survival of the fittest", how does cooperation evolve? Living things form cooperative relationships all the time. Research done by applying mathematics to biology is helping us understand the evolution of cooperation. Cooperation has caused some of the major evolutionary steps in the history of life, including the step from single celled creatures to multi-cellular plants and animals. Scientists used mathematical models to find scenarios in which natural selection will actually favor cooperation.

13 Things Aquariums Are Hiding From You
 
08:34
Do you like visiting aquariums? They are loved by many. They make it possible for people to get acquainted with marine creatures they would otherwise never see. Unfortunately, not everything is so bright about the very concept of aquariums and marine parks. When the documentary "Blackfish" came out, the image of such entertainment establishments underwent a serious damage. Visitors often have a misconception that trainers in aquariums are specialists in marine biology. After all, they have such extensive knowledge about these creatures! Totally wrong. People who interact with animals and participate in shows are only performers. They have no professional credentials about orcas or other marine animals. They’re simply hired to entertain the crowd. #dolphinshow #aquarium #dolphins TIMESTAMPS: Orcas are starved 0:45 People who work with orcas get killed 1:07 Orcas live shorter lives in captivity 1:51 Orcas have to live in tiny tanks 2:27 A collapsed dorsal fin isn't normal 3:17 Drugs are used on killer whales 3:52 Killer whales have problems with their teeth 4:25 Employees paint over the whales' sunburns 4:46 The trainers are not marine biologists 5:23 Captive orcas injure other animals 5:51 They artificially breed killer whales 6:20 Orcas are hurt by chlorine 7:08 Gelatin is used to keep orcas hydrated 7:37 Preview photo credit: Killer whale and trainer during a Shamu performance at Seaworld in Orlando, Florida: By Loadmaster (David R. Tribble), CC BY-SA 3.0 https://creativecommons.org/licenses/by-sa/3.0, https://commons.wikimedia.org/w/index.php?curid=9576553 Animation is created by Bright Side. Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY: - Giving a treat is a typical approach while training an animal. But unfortunately, these treats seem to serve as usual food. Employees are instructed to keep the orcas hungry. - In the wild, male orcas live for 70 years, while the females’ lifespan is even longer: 100 years. But in captivity, orcas don't have a chance to enjoy a long happy life. In most cases, they die as teenagers, usually after they turn just 13 years old. - The tanks these animals live in are immensely small for them. In fact, the length of one tank is one-millionth of the distance an adult orca can cross a day in the ocean. - In the wild, only 1% of all orcas suffer from problems with their fins. And if they do, it means they're sick or injured. - If orca misbehaves or gets too excited, trainers force-feed it sedative drugs. - To prevent the public from asking questions about the change of color on the whales’ skin, trainers cover their sunburns with zinc oxide. This substance is black and does a good job at masking the horror. - People who interact with animals and participate in shows are only performers. They have no professional credentials about orcas or other marine animals. - When orcas live in captivity for prolonged periods of time, they become extremely aggressive. But they don’t just hurt the trainers; they fight each other and other animals as well. - Chlorine levels in tanks are way too high and damage the health of the animals kept in them. As a result of all the chlorine, killer whales have mucus running from their eyes and problems with their vision.

Why Whales Became the Biggest Animal of All Time
 
09:12
Today’s whales can grow up to a whopping 98 ft in length! But did you know that just a few million years ago they only grew to about 32 ft? Have whales been eating loads of spinach all these years, or did something shift over time that made them grow into the massive sea beasts they are today? In fact, when whales first came on the scene nearly 50 million years ago, they looked nothing like they do today. In fact, they didn’t even live underwater! And today, some whales still have remnants of what used to be a bone for a hind leg in their skeleton (it just doesn’t show outside the skin). Could you imagine if whales still sported legs like their early ancestors did? That would look pretty funny.

Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY: - Pakicetus was a 4-footed land mammal and is known as the “first whale.” It was about the size of a wolf and was a carnivore. These mammals lived on land by shallow waters known as the Tethys Sea. - Some scientists believe that Pakicetus was a land dweller who was forced to swim in the ocean due to lack of food on land or warm temperatures. As they spent more and more time in the water, the animal evolved into a creature that lived in the sea. - One of the first evolved animals to come from Pakicetus was a species known as Ambulocetus. It lived near estuaries somewhere between 50 to 48 million years ago. - Over a period of about 37 million years, Pakicetus gradually evolved into over 80 different species of whales. That’s why 27.5 million years ago, one of the first whales was significantly smaller than they are today. - Whales definitely didn’t start out as the titans of the sea they are today as their smaller size made them easy prey for predators like hungry sharks. - To say whales were well fed at this time was an understatement! Whales everywhere filled their tummies with scrumptious krill, and they grew larger and larger. - Whales are consistently the biggest animal on our planet these days. The blue whale, for example, weighs more than a Boeing 757 — passengers and bags of peanuts not included. And their belly buttons are the size of a dinner plate! - While science has proven that whales have evolved from Pakicetus, they have another possible relative that still lives on Earth with us today: hippos! - Many scientists believe that whales have hit their capacity for growth once they measure 109 ft. That’s because at 110 ft, a whale can’t physically close their mouth within 10 seconds before its prey escapes. If it took any longer, they wouldn’t be able to eat, which would lead to their death.

7 Most Giant Sea Creatures You've Ever Seen
 
09:46
What are the biggest creatures in the world? If you wanna find the true giants of this planet, you’ll need to head into the ocean. Without the force of gravity pulling them down, marine animals can reach unimaginable sizes. TIMESTAMPS: The Giant Clam 1:37 The Giant Spider Crab 2:41 The Great White Shark 3:45 The Whale Shark 4:52 The Fin Whale 5:49 The Lion’s Mane Jellyfish 6:39 The Blue Whale 7:53 Music: https://www.youtube.com/audiolibrary/music SUMMARY: - Giant Clams are the largest mollusks in the world. They can grow around 4 feet in length and weigh more than 440 pounds. - The giant spider crab lives in the waters near Japan. Their legs reach about 11.5 feet from claw to claw and the body can be around 14.5 inches in diameter, which is pretty small compared to their long long limbs. - The great white gets its name from its distinct white belly under its grey body. As for the “great” part, that’s simply because some of them can grow over 20 feet long! As for your average great white shark, it’s usually about 15 feet in length, making it the largest predatory fish in the world. - The whale sharks are covered in white spots that have a unique design for each individual shark. The whale shark ranges in size from 18 to 32.8 feet and can weigh about 20.6 tons. - The fin whale can get up to 85 feet long. That’s the length of two school buses! It can weigh up to 75 tons, which is about as much as a space shuttle! - The lion’s mane jellyfish can get up to 120 feet long, putting the lion’s mane jellyfish among the ranks of the world’s longest animals and certainly the largest jellyfish species. It likes to float in the open ocean, where it feeds on zooplankton, small crustaceans, fish, and even other types of jellyfish. - The blue whale is the largest animal this planet as ever seen, and it still swims the oceans today. They range from 82 feet to 105 feet in length and weigh up to a massive 200 tons. That’s as much as an empty Boeing 747!

10 Strangest Ocean Phenomena You Won't Believe!
 
04:14
Top 10 Amazing things that occur in the deep blue ocean. Creatures, and strange underwater events! Subscribe to our channel: http://goo.gl/9CwQhg For copyright matters please contact us at: [email protected] Description: With water covering 70% of the Earth’s surface, it’s no wonder that oceans yield spectacular species, with scientists finding up to four new species a day, according to the World Register of Marine Species, or WoRMS. They add that there are also approximately 228,450 marine species known to scientists with some two million more multi-celled marine organisms still to be discovered. The ocean is also home to other phenomena including giant beached whales, bioluminescence – when water appears to be glowing - and the yearly migration of millions of red sea crabs on Christmas Island, stopping drivers and pedestrians in their tracks. Seahorses continue to fascinate people time and again, not only for their combination of a norse-like head with S-shaped bodies but also because of what’s seemingly a reversal of roles in the natural world i.e. the male having to do the “pushing.” Rogue waves are an amazing phenomena that could have deadly consequences too, engulfing ships and fishermen in its wake. Short-tail stingrays are also considered to be dangerous. The death of Australian wildlife expert Steve Irwin, “The Crocodile Hunter,” by a sting ray brought the species to prominence in 2006 but in reality, that was a freak occurrence that happens on extremely rare occasions. Sea pens and glass squid appear to go hand in hand, although neither are what they seem. Underwater, famed French marine explorer Jacque Costeau once said “When one man, for whatever reason, has the opportunity to lead an extraordinary life, he has no right to keep it to himself.” Such is the inspiration by marine biologists, sailors, and regular people alike to continue to explore life under water. Despite man’s advancements of NASA and seeking life on other planets, it’s seeing what’s under the earth’s surface where marine life will help us truly understand our human world.

Experimenting on Animals: Inside The Monkey Lab
 
19:46
VICE News gets rare access to Europe’s largest primate testing facility, the Biomedical Primate Research Center (BPRC) in the Netherlands, where scientists try to find cures for the worst human diseases, while claiming to provide unparalleled care for the monkeys in the hope they live the most animal friendly life before and during testing. Once selected, inside the laboratories, monkeys are shaved, anesthetized, and experimented on for research purposes. Yet the center remains controversial. Protestors gather regularly in front of its gates and there are calls in the Dutch parliament to close the site and switch to alternatives for testing on primates. But as the BPRC explains to VICE News, modern science isn't there yet. In the meantime, it still uses about 200 monkeys a year for a slew of experiments to find cures, and even replacements for primate testing in the future.

Developmental biology part 1 : introduction and grey crescent formation

For more information, log on to- http://shomusbiology.weebly.com/ Download the study materials here- http://shomusbiology.weebly.com/bio-materials.html Embryogenesis is the step in the life cycle after fertilisation -- the development of the embryo, starting from the zygote (fertilised egg). Organisms can differ drastically in how the embryo develops, especially when they belong to different phyla. For example, embryonal development in placental mammals starts with cleavage of the zygote into eight uncommited cells, which then form a ball (morula). The outer cells become the trophectoderm or trophoblast, which will form in combination with maternal uterine endometrial tissue the placenta, needed for fetal nurturing via maternal blood, while inner cells become the inner cell mass that will form all fetal organs (the bridge between these two parts eventually forms the umbilical cord). In contrast, the fruit fly zygote first forms a sausage-shaped syncytium, which is still one cell but with many cell nuclei.[18] Patterning is important for determining which cells develop into which organs. This is mediated by signaling between adjacent cells by proteins on their surfaces, and by gradients of signaling secreted molecules.[19] An example is retinoic acid, which forms a gradient in the head to tail direction in animals. Retinoic acid enters cells and activates Hox genes in a concentration-dependent manner -- Hox genes differ in how much retinoic acid they require for activation and will thus show differential rostral expression boundaries, in a colinear fashion with their genomic order. As Hox genes code for transcription factors, this causes different activated combinations of both Hox and other genes in discrete anteroposterior transverse segments of the neural tube (neuromeres) and related patterns in surrounding tissues, such as branchial arches, lateral mesoderm, neural crest, skin and endoderm, in the head to tail direction.This is important for e.g. the segmentation of the spine in vertebrates. Embryonic development does not always proceed correctly, and errors can result in birth defects or miscarriage. Often the reason is genetic (mutation or chromosome abnormality), but there can be environmental influence (like teratogens) or stochastic events. Abnormal development caused by mutation is also of evolutionary interest as it provides a mechanism for changes in body plan (see evolutionary developmental biology).

Why Triassic Animals Were Just the Weirdest

Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/DonateEONS Try CuriosityStream today: http://curiositystream.com/eons The Triassic was full of creatures that look a lot like other, more modern species, even though they’re not closely related at all. The reason for this has to do with how evolution works and with the timing of the Triassic itself: when life was trapped between two mass extinctions. Thanks to Ceri Thomas for the Drepanosaurus reconstruction. Check out more of Ceri's paleoart at http://alphynix.tumblr.com and http://nixillustration.com And thanks as always to Nobumichi Tamura for allowing us to use his wonderful paleoart: http://spinops.blogspot.com/ Finally, thanks to Emilio Rolandia, Matt Celeskey, and Studio 252mya for their excellent images as well.

This article focuses on the segmentation of animal body plans, specifically using the examples of the taxa Arthropoda, Chordata, and Annelida. These three groups form segments by using a "growth zone" to direct and define the segments. While all three have a generally segmented body plan and use a growth zone, they use different mechanisms for generating this patterning. Even within these groups, different organisms have different mechanisms for segmenting the body. Segmentation of the body plan is important for allowing free movement and development of certain body parts. It also allows for regeneration in specific individuals.

Life is difficult to define, but there are characteristics of life that can be explored! Join the Amoeba Sisters as they explore several characteristics of life. Click "show more" to expand video details to see table of contents & additional information. 👇 We chose not to give a numerical value for how many characteristics of life there are, because we do not want to imply that what we are listing must be a specific order, or that it cannot be expanded upon or include exceptions. Additionally, characteristics can also certainly be titled differently. Our goal is to promote thought and discussion about what it means for an organism to be alive as well as provide characteristics of life that can be explored when trying to study living things. CHARACTERISTICS OF LIFE MENTIONED IN THIS VIDEO: Organization (all life is composed of 1 or more cells) 2:20 Homeostasis 2:54 Metabolism (including need to obtain+use energy) 3:35 Reproduction 4:22 Growth and Development 4:46 Response to Stimuli 5:10 Evolution (occurs in populations, can lead to adaptation) 5:58 While living organisms tend to have ALL of the above characteristics, there are exceptions (such as the 'zonkey' mentioned in video at 6:55). *Quote Citation: Mullen, Leslie.

Biological pigments include plant pigments and flower pigments. Many biological structures, such as skin, eyes, feathers, fur and hair contain pigments such as melanin in specialized cells called chromatophores. Pigment color differs from structural color in that it is the same for all viewing angles, whereas structural color is the result of selective reflection or iridescence, usually because of multilayer structures. For example, butterfly wings typically contain structural color, although many butterflies have cells that contain pigment as well.

Many of his observations were made during his stay on the island of Lesbos, including especially his descriptions of the marine biology of the Pyrrha lagoon, now the Gulf of Kalloni. His theory is based on his concept of form, which derives from but is markedly unlike Plato's theory of Forms. The theory describes five major biological processes, namely metabolism, temperature regulation, information processing, embryogenesis, and inheritance. Each was defined in some detail, in some cases sufficient to enable modern biologists to create mathematical models of the mechanisms described. Aristotle's method, too, resembled the style of science used by modern biologists when exploring a new area, with systematic data collection, discovery of patterns, and inference of possible causal explanations from these. He did not perform experiments in the modern sense, but made observations of living animals and carried out dissections. He names some 500 species of bird, mammal, and fish; and he distinguishes dozens of insects and other invertebrates. He describes the internal anatomy of over a hundred animals, and dissected around 35 of these. Aristotle's writings on biology, the first in the history of science, are scattered across several books, forming about a quarter of his writings that have survived. The main biology texts were the History of Animals, Generation of Animals, Movement of Animals, Progression of Animals, Parts of Animals, and On the Soul, as well as the lost drawings of The Anatomies which accompanied the History. Apart from his pupil, Theophrastus, who wrote a matching Enquiry into Plants, no research of comparable scope was carried out in ancient Greece, though Hellenistic medicine in Egypt continued Aristotle's inquiry into the mechanisms of the human body. Aristotle's biology was influential in the medieval Islamic world. Translation of Arabic versions and commentaries into Latin brought knowledge of Aristotle back into Western Europe, but the only biological work widely taught in medieval universities was On the Soul. The association of his work with medieval scholasticism, as well as errors in his theories, caused Early Modern scientists such as Galileo and William Harvey to reject Aristotle. Criticism of his errors and secondhand reports continued for centuries. He has found better acceptance among zoologists, and some of his long-derided observations in marine biology have been found in modern times to be true.
