Mucoid capsules prevent desiccation in some organisms which increase virulence. Capsules are slippery and can evade a human's immune system.
To find out, scientists can locate where these monsters are. The one thing trhat really helps is to calculate where Great Whites live and dive. Then they look at the behavior of the Great White. the behavior leads to the poles. And believe it or not, they found a few samples of Megalodon. These giant monsters aren't extinct. One way to see one is to throw out in the ocean, more than a Great White can handle. Hopfully you should start seeing some fins in an hour. Never throw the fish next to the boat or the shark might kill you.
How did a megalodon protect itself?
It didn't need to. Nothing was big enough to even consider harming it; other megalodons would not bother attacking each other (apart from the young which would have been easily overcome).
Why is the shadow of your body taller than you?
Depending on which angle the sun is in relation to your body your shadows length can change.
Water dragons are a type of reptile that some people keep as pets. For the most part they are very docile and can be held. However they can sometimes become agitated and bite if they do not want to be held.
What is the average time that a species spends on earth before it becomes extinct?
It depends on which species is, humans have been here for a while, but so have many more, it just depends on how large of a population, and how messed up the food chain is
Auks live in the northern hemisphere (north of 25°N). They are relatives of penguins but can fly.
Not known very definitely.
The last confirmed sighting was in 1662, but there were contested sightings as late as 1674. Statistical analysis of the numbers of birds taken in hunting expeditions suggests a curve descending to zero in about 1693.
The dodos were not literally hunted to extinction by humans, but they were also killed by introduced rats, dogs, cats, and monkeys (most of which ate the eggs and nestlings, rather than the adult birds). Therefore, the last dodo killed by a human hunter was not necessarily the last dodo alive.
Why do most species of animals become extinct?
Most become extinct because they can not adapt to changes in their environments. Those that can don't become extinct.
Is this true or false an extinct animal is one that lived in the time of the dinosaurs?
It is true that most animals alive during the time of dinosaurs are now extinct. However, any animal can go extinct, even in modern times.
For instance, the pallid beach mouse went extinct in 1959. The Pyrenean ibex went extinct in 2000. The eastern cougar went extinct in 2011.
Extinction simply means there are no animals of that type left. They have all been wiped out through hunting, deforestation, illness, or other reasons.
Are dinosaurs recent or ancient history?
Dinosaurs are considered prehistorical. Recent and ancient history usually refers to the existence of the human race.
Who are the compass jellyfish preadtors?
They do not have many predators. The only ones seaming to be other compass jellyfish, and human pollution. They are not endangered or threatened.
Why did carnivora outcompete mesonychia and creodonta?
Mesonychids:
There were two main disadvantages as concerns Mesonychids against both Carnivores and Creodonts. First, Mesonychids were generalized hunters making them less capable in any specific habitat and affording that benefit to Carnivores and Creodonts. Second, Mesonychids were generally larger than Carnivores and Creodonts and required more food to sustain them. As a result, they were out-competed.
Creodonts:
Creodonts share some benefits with Carnivores like binocular vision, claws, and shearing carnassial teeth. Some species even had more bite force than carnivores, but they had two distinct disadvantages. They were neither as fast or as efficiently designed as Carnivores. They also lacked the raw intelligence that Carnivores had, allowing Carnivores to hunt in packs and establish social relationships. Additionally, Carinvore intelligence led to more advanced hunting procedures and "hand-eye" coordination.
