Animals

  • Mosquitoes don't drink human blood for food. Females drink human blood so they can reproduce. As soon as the female lays it's eggs, it dies. Males feed on nectar and they pollinate our gardens.
  • A lions roar can be heard from a mile away.

  • Vampire bats do not suck blood. They make a wound with their teeth and their saliva keeps the blood from clotting. Then they lap up the flowing blood. Vampire bats feed mostly on cattle blood. The digestion of the blood causes the toxic gas ammonia (NH3) to form.
  • Pet owners released the Burmese pythons into Florida's Everglade swamps. Those pythons then started breeding and also devouring America's famous American alligator.

  • Venomous snakes usually have their fangs in the front of their mouth, and non poisonous have them in the back of their mouth. But there are a few exceptions.

  • Peregrine falcons are the fastest animals on earth. They dive at a top speed of 200mph

  • Crab spiders wait on plants and blend into in so when insects land to pollinate, they are devoured. Even stinging insects cannot escape because they are not fast enough for the crab spider.

Ancient History

Crotalus!!! (with videos)

Crotalus is a scientific name meaning rattler. You can recognize it by the first word in scientific name for rattlesnakes.
Rattlesnakes are venomous snakes that belong to a family called pit vipers. It is the most feared snake in U.S.A. Some rattlesnakes are large like the eastern and western diamond back rattlesnakes and small like the pygmy rattlesnakes. Rattlesnakes cause about 200,000 deaths a year. Most deaths are in North America from Canada to Mexico and some in South America. The way these snakes were named was by their warning rattle.

Rattle snakes can survive in different climates, for example the Cascabel is a South American rattlesnake. It can survive in tropical regions. Also the mojave(Moe-ho-vae) rattlesnake can survive in desserts and caves...caves...caves...

Rattlesnakes use himo toxic venom. Soon there will be heart and lung failure to the victim. All rattlesnakes along with snakes are carnivores, the smallest of snakes eat insects while bigger snakes prey on animals as big as deer. Rattlesnake diets include - large insects, rats, mice, other rodents, rabbits and small birds.
While hunting the snake has to track down it's prey, and how does it do that? That's easy they catch scent molecules with their fork shaped tongue. Then they take the tongue to the bottom of their upper jaw. The upper jaw has an organ that senses what that is, and that is how they track down their prey. The rattle snake then uses it's pits to see how warm the prey is. Lastly it strikes the prey when the prey wanders closely. It uses a muscle to get venom from the gland and drops in enough venom to kill it's prey. For rodents it lets them run off and it tracks them down till their dead. But for birds they hold on.

Although rattlesnakes are aggresive and venomous. they do have predators. Birds of prey, and other carnivores such as bobcats, coyotes, wolves, Indigo Snake, and King snakes

Animals

Animals are one of the things I love most. It is cool looking at their way of survival. Some animals already have gone extinct, either beacause of deforestation, hunting, or change in enviroment.
For example: When humans found the dodo bird it was hunted to death. Or like when rats were realesed in Austrailia some flightless birds have gone extinct. So let us try our best to keep the habitat the same and see how we can save Austrailian reptiles from going extinct from the cane toad or to convince the chinese president to not open up the tiger trade.
Different animals have different ways of living, most animals have different heartbeats and diets.
Like every other living organism on earth, animals have to move, reproduce, sense, grow, resperate, excrete, and have lots of nutrition.
Live to preserve, preserve to live!!!
