What Is Extinction?

There are thousands, if not millions, of species of organisms on our planet. Many species that used to exist no longer do; these species are called extinct. The most common example of an extinct species are the dinosaurs. These large animals, which once roamed the Earth, can no longer be found today. While the dinosaurs became extinct because of a meteor hitting the Earth, humans are the primary cause of species extinction today.

How Do Organisms Go Extinct?

Hunting, deforestation (or chopping down forest for land to build on), and overfishing are all human practices that contribute to the decline in species numbers. When the natural population numbers of a species get low, there are two terms that can be used to describe that species. These are threatened and endangered.

The International Union for Conservation of Nature (IUCN), also known as the World Conservation Union, was founded in 1948 and is primarily responsible for classifying species as threatened or endangered. The IUCN considers a species threatened if the population is vulnerable to endangerment in the near future. A species is considered endangered if the population faces a high risk of extinction. The IUCN has seven different categories in which they classify species. These are:

Least Concern - There is no immediate threat to the survival of the species. These are typically common species that have been hunted or can be hunted, but no harm is done to the population as a whole. Examples of these species are the Canadian goose and the American alligator.

Near Threatened - These are species that could be considered threatened in the near future, and population numbers are monitored carefully. Examples of near-threatened species are the emperor penguin and the American bison.

Vulnerable/Threatened - These are species that face a high risk of extinction, but not for many years. These species are typically hunted for pelts and trophies - for example, lions for pelts and African elephants for ivory - or have lost a significant amount of their habitat, such as Komodo dragons and Galapagos tortoises.

Endangered - These organisms face a high risk of extinction in the near future. Examples include Asian elephants, green sea turtles, and blue whales. These populations are closely monitored, and there are considerable fines and jail time if someone is found hunting or harming a species that is considered endangered.

Critically Endangered - A species in this category is likely to go extinct in the near future unless drastic measures are taken to ensure its survival. Many of these species were over-hunted or over-fished and continue to be hunted illegally, also known as poaching. Examples include the mountain gorilla, bluefin tuna, and the California condor.

Extinct in the Wild - This means that while no living members of a certain species exist in their native habitat, there are individuals in captivity. The best example of a species that is extinct in the wild is the northern white rhinoceros. The white rhino was over-hunted and killed for its horn, which is considered to be extremely valuable. In fact, park rangers are now cutting the horns off rhinoceros in the wild so they won't be killed by poachers.

Extinct - No living members of these species exist. Examples of organisms that have gone extinct include the previously mentioned dinosaurs, wooly mammoths, and dodo birds. Many of these species we only know existed from fossil records or by finding their bones buried in the ground. These are the animals that you typically see when you visit a natural history museum. However, there are numerous species that have gone extinct purely from the actions of humans. Some examples include the western black rhinoceros (which was declared extinct in 2011), the Japanese river otter (which was declared extinct in 2012), and the Formosan clouded leopard, which was declared extinct in 2013.

Definition of an Amphibian

You may remember catching frogs in the summertime as a child. It was no easy feat, sneaking up on the slippery buggers and trapping one in your hands. Perhaps near a pond, the frogs could make a quick escape into the water with a splash. Frogs are probably the most recognizable and certainly the most abundant members of a class of animals known as amphibians. But, frogs and toads are certainly not the only members of this group.

Amphibians are animals that belong to the phylum Chordata. Among other things, animals in the Chordata phylum have a backbone. Amphibia is a class within the Chordata phylum, and there are three subgroups, or orders, included. Our well-known friends the frogs and toads belong to the order Anura. However, two additional orders, Urodela and Apoda, also belong here. We will take a closer look at all of these animals as we explore the world of amphibians.

Characteristics of Amphibians

The word amphibian means dual lives. You may have seen an amphibious car, one that drives on land and then heads straight into the water and functions like a boat. In the world of amphibians, this idea of dual lives pertains to the youngster stage and quite different adult stage that most of them undergo. Let's take a closer look at frogs as an example.

Frog babies hatch into water as tiny tadpoles with no legs or lungs. Closely resembling fish, these frog youngsters swim using their tails and breathe through gills. And then a dramatic metamorphosis occurs. Losing the tail and the gills, the tadpole grows legs and transforms into a frog. Our adult frog crawls up onto the shore, now spending time both in and out of the water. Hence, a dual life.

Amphibians have other defining trademarks that make them who they are. First, they are cold-blooded creatures. If you enjoy warm and fuzzy pets, an amphibian may not be the one for you. Amphibians are at the mercy of the environment around them. They have to regulate their temperature by physically moving to or away from the heat source. If it's an extremely hot day, you'll probably find them lounging in the pond.

Another important characteristic of this class of animals is the fact that amphibians have moist, scaleless skin. Think back to catching those frogs. You could feel the thin, slippery layer covering its body. It is for this reason that frogs and their relatives must stay close to water at all times. And, it's not just because they enjoy swimming.

Amphibians absorb their water right through their skin. Unlike their reptile cousins that have thick scales covering their bodies, the skin of an amphibian is extremely thin and fragile. This allows water to penetrate but also puts them at high risk of dehydration. And so, their favorite hangouts are watery destinations such as ponds, lakes, and swamps.

An amphibian's skin has another crucial job, which is gas exchange. Frogs and their relatives actually breathe through their skin as adults. Although adult amphibians do have lungs, they function rather poorly. Oxygen gas is absorbed, and carbon dioxide is released, right through the very thin covering of these creatures. Thus, it is even more important for them to keep their skin moist and protected.

Orders of Amphibians

Amphibians are grouped according to two bodily characteristics: legs and a tail. Urodela is the order of amphibians with both legs and a tail. With about 400 different species, including salamanders, a defining characteristic of a urodele is that it has a tail that lasts into adulthood. Crawling on land with four legs, this guy may be confused with a reptile. However, upon close examination, the same moist, scaleless skin as our frog friends can be observed. A newt is another example of a urodele.

Aquatic Animals

Do you know why Sponge Bob Square Pants is a sponge? He is a sponge because one aquatic animal is called a sea sponge. However, sea sponges do not look like a square kitchen sponge, but have a more rounded shape. Aquatic animals are animals that live in the water. They either live in fresh water, such as lakes, rivers, and ponds, or salt water, like the ocean.

Most people only think of fish when asked about aquatic animals. However, there are other groups of animals that live in the water, such as mammals (like whales), mollusks (such as sea snails), cnidarians (also known as jellyfish), and crustaceans (like crabs).

Fish & Mammals

Did you know that there are more different types of fish than the amount of amphibians, birds, mammals, and reptiles combined? Fish are aquatic animals because they live all of their lives in water. Fish are cold-blooded, and they have gills that take in oxygen from the water to breathe. In addition, fish are vertebrates, which means that they have a backbone. Think about your back and the column of vertebrae, or disks in the back, that run down the center. Fish have the same structure. While most fish can live in only freshwater or saltwater, some fish, such as salmon, live in both.

While fish only live in water, mammals can be found on land and in water. All mammals are vertebrates; have lungs; give birth to live babies, as opposed to laying eggs; and are warm-blooded. However, aquatic mammals depend on water to live. Some mammals, such as whales and dolphins, live only in water. Others, however, such as beavers and seals, will exit the water for periods of time. Because they have lungs and not gills, aquatic mammals cannot breathe underwater. Rather, they have to come to the surface to get air. If you have ever seen what looks like a spout of water coming out of a whale's blowhole, this is the whale exhaling and then inhaling before he dives back under.

Mollusks, Cnidarians, & Crustaceans

Mollusks are invertebrates, which means they do not have a backbone. In addition, they have soft bodies and no legs. For this reason, many mollusks grow a hard shell to protect their soft bodies when they need to hide from predators. Sea snails and clams are examples of aquatic mollusks with shells. Squid and octopuses are also aquatic mollusks, but they do not have shells. What we call an octopuses' legs are actually called tentacles and are used to feel around.

Arboreal animals are creatures who spend the majority of their lives in trees. They eat, sleep and play in the tree canopy. There are thousands of species that live in trees, including monkeys, koalas, possums, sloths, various rodents, parrots, chameleons, geckos, tree snakes and a variety of insects. Many animals have evolved special adaptations to aid their arboreal lifestyles.

Warm Blood

If your temperature is a degree higher than normal, you may start to worry. You may even miss school. If your temperature is a degree cooler than normal, you might worry about that, too. Why are we so concerned over tiny changes in our temperatures? It's because humans are warm-blooded creatures, which means that our bodies try really hard to maintain a constant temperature, regardless of external factors. Biologists call warm-blooded animals endothermic, since heat is generated from within the body. While cold-blooded animals must rely on their environment to control their body temperatures, warm-blooded animals do this naturally. Our bodies can keep us at a constant temperature. This system keeps our bodies warm, and we've got to admit that's pretty cool!

Warm-Blooded Animals

Of all the millions of species of animals in the world, only a relatively small number are warm-blooded. Basically, warm-blooded animals include birds and mammals. There are many birds and mammals in the world, but not nearly as many as there are insects, fish, reptiles, and amphibians. Since birds and mammals are the most recent class of animals, this means that warm-bloodedness is a relatively young adaptation that probably occurred when these animals were evolving.

Now, what was happening around the time that warm-blooded animals evolved? While both mammals and birds likely appeared during the age of the dinosaurs, their evolution really took off after the dinosaurs died. The death of the dinosaurs was soon followed by the beginning of the Ice Age, and being warm-blooded may have been extremely beneficial.

Within a few million years, the tiny mammals had grown into massive mammoths and other Ice Age creatures that dominated the Earth. Since birds are warm-blooded, many scientists also now think that some dinosaurs may have evolved an early system of temperature regulation, especially the group called the theropods, from which birds evolved. Theropods include dinosaurs like T-rex and velociraptor. While this is an exciting idea, it's still a hotly debated topic.

Staying Warm

Warm-blooded animals are defined by their ability to maintain a consistent body temperature, without relying solely on external factors like sunshine or shade. So, how do they (and we) do it? Warm-blooded animals have many ways to keep themselves warm. Birds and mammals both shiver to generate heat through rapid muscle contraction, and many mammals have thick layers of fur or fat to insulate body heat.

The most important system however, and the one that really defines all warm-blooded animals, is the ability to generate heat from the energy in food. All food has energy stored within it, and warm-blooded animals are able to convert the majority of that energy into heat. That's how we maintain a constant body temperature. This does mean that warm-blooded animals have to eat much more food than cold-blooded animals, who only have to eat enough to keep basic body systems functioning. The majority of our food actually goes to heat production, so while crocodiles can eat once a week, we need to eat several times a day.

The new BBC series Planet Earth II, like the Planet Earth that came before it, promises to take you deep into the natural world, to places that humans without multimillion-dollar budgets could never tread. Cold places, searing places, tippy-top-of-mountains places.

As a companion to the series, the BBC is releasing incredible 360-degree videos that immerse you in the action like never before. And the latest, embedded above, drops you in the middle of a Costa Rican rainforest to meet a giant snake, a less giant but still fascinating snake, and a lizard that can walk on water. NBD. Just click and drag to look around like Sir Attenborough himself.

(This is the third of six 360-degree videos that the BBC will be publishing. Scroll below to see more.)

We all know by now what a fox says, thanks to a certain song we all by now have heard too many times. But have you ever wondered what a fox sees? Well wonder no further, for the BBC is here to put you in a fox's tiny shoes.

In the engrossing 360-degree video above, you're a fox on a perilous nighttime adventure through the big city, specifically Bristol in England. (Yes, urban foxes are definitely a thing over there.) Just click and drag to look around at treasures and dangers alike, from an easy meal to your arch enemy: the family dog.

(This is the final of six videos the BBC put out with the release of Planet Earth II. Scroll down to watch the others!)

Think about the most nightmarish place to be stranded at night. An abandoned mental hospital, perhaps? A Justin Bieber concert? Nope-trifles compared to standing smack in the middle of an African savanna.

Check out the BBC video above. Listen to the 360-degree spatial sounds of lions grumbling and hyenas cackling and elephants trampling through the bush. Click and drag to look around as very dangerous creatures sneak up on you. And understand just how perilous life is for Africa's animals in the dead of the night. Also, appreciate that humans have largely removed themselves from the food chain.

(This is the fifth of six remarkable 360-degree videos marking the release of Planet Earth II. Scroll down to see the rest!)

Deserts are living contradictions: seemingly empty but in fact packed with life, burning hot by day yet freezing cold by night, and arid save for that odd flash flood that tears through the land, gouging out great canyons. And nowhere are these canyons more dramatic-and dangerous-than in Arizona.

For its new series Planet Earth II, the BBC paid one such chasm a visit. Oh, and they brought along a 360-degree camera, which means by clicking and dragging the video above, you too can drop into the canyon. It's much safer this way-trust me. Should a flash flood come through, if the water itself doesn't kill you, the boulders it carries most certainly will.

(This is the fourth of six 360-degree videos the BBC is publishing as companions to Planet Earth II. Scroll down for more!)

Filming nature documentaries is a singular pursuit-often terrible conditions, lots of things biting you, and lots of waiting for your subject to show up. And it doesn't get much more challenging than tracking snow leopards in the Kashmir mountains. This is one of the most elusive cats on Earth, living in one of the most inhospitable environments on Earth.

So to capture a snow leopard for David Attenborough's new series Planet Earth II, the crew had to combine patience, luck, and a whole lot of fancy tech. They deployed camera traps along the mountain passes, capturing (ever-so-briefly) their prize walking past. Eventually, they captured more than they could have ever hoped for using a camera loaded with a good-ol' giant lens: the first sighting of snow leopards mating in the wild.

You can see it all above in glorious 360 degrees (click and drag to look around), from the pursuit to the payoff. And hey, bonus: nothing will bite you in the process. (This is the second of six behind-the-scenes 360-degree videos we'll be publishing from the series. Check back in this thread for more as the BBC releases them.)

David Attenborough's Planet Earth ranks as one of the all-time great nature documentaries, an epic journey that took viewers to ice worlds and rainforests and down into caves to reveal the stunning biodiversity of this planet. And now, the BBC is out with a sequel, aptly titled Planet Earth II, which promises even more spectacle-and shiny new technologies to pull viewers deeper into the action.

Above you'll find the first of six behind-the-scenes videos the BBC is releasing as companions to the new series. But not just any videos: These are 360-degree films. Click and drag on the picture and you can actually look around as the crew works its magic. See how they prepped to shoot an epic battle between snakes and baby iguanas (the final astounding footage you probably saw bouncing around on social media over the past few days but we won't link to here because I don't think the BBC would appreciate it none), and dive with playful Galapagos fur seals. It's an immersive new way to experience nature, and it's most certainly the future of natural history.

We'll be rolling out five more 360-degree videos as the BBC releases them, so check back!
