Northern Manatee example essay topic

The Manatee My report is on the manatee, specifically, the Northern Manatee, better known as the West Indies or West Indian Manatee. The scientific name of the Northern Manatee is Trichechus Manat us. The Manatee is a versatile animal when it comes to it's habitat. It lives mostly in shallow salt water, although it has been known to live in freshwater, and deep salt water. The Northern Manatee's main population is in rivers in Florida and the Caribbean Isles and Sea, although there are exceptions, such as if the manatee gets hurt, it may go to SeaWorld or places like it, to be healed and recover. The Northern Manatee can and has adapted to humans in it's habitat.

Since the Northern Manatee has no natural predators, it can live in any shallow salt water, and comes to many areas with live coral reefs. The Northern Manatee grows inside it's mother for a year or more before the calf is born. The calf stays with it's mother for around two years. At birth the Manatee is a little more than three feet (1 meter) long, and weighs from 25 to 60 pounds. Adult manatees are on average seven to twelve feet in length, although some have been known to grow up to fifteen feet. The manatee is one of the only marine mammals.

Unlike most mammals, the manatee does not have calves every year. The female manatee has one calf every two to three years. The Northern Manatee swims at an easy pace of five miles an hour. If the animal is frightened, it swims at a faster pace of fifteen miles an hour. The manatee eats underwater vegetation, using it's weak front flippers to push the food into their mouth. The manatee can eat up to one hundred pounds of underwater vegetation a day.

The manatee has a round, powerful, flat tail. The tail is the manatee's main propulsion. Most mammals have seven vertebra in the neck. The manatee has six in thei neck.

The manatee has twenty to thirty molars. Since all manatees look suprisingly human when they have their shoulders and head out of the water, it is thought that they may have started the mermaid rumors / stories. The manatee has very weak front flippers. They have been heavily hunted in the past, although they are now protected because they are endangered animals.

It is thought that the manatee communicates by contact, more specifically, muzzle to muzzle contact. The manatee is almost hairless, except for their mustaches. The manatee has leathery skin. Manatees are sometimes called sea cows. This is because manatees are quiet and peaceful. Their only defense is to swim away.

Since the manatee has no natural predators, the only danger to it is man. The main reason for the manatee getting killed by man is that the manatee is a very curious animal. It will sometimes swim up to a boat and get hit by it or it will sometimes get cut up by the boat propeller.
