An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. The two living species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). In addition, several extinct species of alligator are known for fossil remains. Alligators first appeared during the Oligocene epock about 37 million years ago. The name "alligator" is probably an anglicized form of el lagarto, the spanish term for "the lizard", which early Spanish explorers and sttlers in Florida called the alligator. Later English spelligs of the name included allagarta and allagarto. A typical adult American alligators weight and length is 360 kg (790 lb) and 4.0 m (13.1 ft), but the sometimes grow to 4.4 m (14 ft) long and weigh over 450 kg (990 lb). The largest ever recordes, found in louisiana, measured 5.84 m (19.2 ft). The Chinese alligator is smaller, rarely exceeding 2.1 m (6.9 ft) in length. In addition, it weighs consierably less, with males rarely over 45kg. No average lifespan for an alligator has been measured. In 1937, a one-year-old speciman was brought to the Belgrade Zoo in Siberia from Germany. It is now 76 years old. Although no valid record exist about its date of birth, this alligator, officially named Muja, is considered the oldest alligator in captivity. Alligators are native only to the United States and China. American alligators are found in the southeast United States: all of Florida and lousiana, the southern parts of Georgia, Alabama, and Mississsippi, coastal south and North Carolina, East Texas, the southeast corner of Oklahoma, and the southern tip of Arkansas. According to the 2005 Scholastic Book of World Records, Louisiana has the largest alligator population. The majority of American alligators inhabit Florida and Louisiana, with over a milion alligators in each state. Southern Florida is the only place where both alligators and crocodiles live side by side. American alligators live in freshwater enviroments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as in brackish enviroments. When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. They are, therefore, considered an important species maintaining ecological diversity in wetlands. Further west, in Louisiana, heavy grazing by nutria (coypu) and muskrat are causing severe damage to coastal wetlands. Large alligators feed extensively on nutria, and provide a vital ecolgical service by reducing nutria numbers. The Chinese alligator currently is found only in the Yangtze River valley  and is extremely endangered, with only a few dozen believed left in the wild. Indeed, far more Chinese alligators live in zoos arounf the world than can be found in the wild. Rockefeller Wildlife Refuge in southern Louisiana has several in captivity in an attempt to preserve the species. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. Large male alligators are solitary territorial animals. Smaller alligators can often be found in large numbers close to each other. The largest of the species (both male and females) defend prime territory; smaller alligators have a higher tolerance for other alligators within a similar size class. Although the alligator has a heavy body and slow metabolism, it is capable of short bursts of speed, especially in very shorts lunges. Alligators' main prey are smaller animals they can kill and eat with a single bite. They may kill largey prey by grabbing it and dragging it into the water to drown. Alligators consume food that cannot be eaten in one bite allowing it to rot, or by biting it than spinning or convulsing wildly until bite-sized chunks are torn off. This is referred to as a "death roll". Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. An alligator
Particularly in the Southeastern United States, humans and the American Alligator, Alligator Mississippiensis, have had a long and harsh relationship. In Florida, the American Alligator (also called a gator) has gone from plentiful bounties, to nearly becoming extinct, and then back to the healthy population that it is at today of about a million. The story of the American Alligator is one that is full of both tragedy and success.
The alligator habitat consists of primarily freshwater ecosystems, which…

The Everglades: A Food Web Diagram
The Everglades is a two million acre wetland ecosystem. The Everglades reaches from central Florida, near Orlando, all the way south to Florida Bay (National Wildlife Federation, 1996-2013). During the wet season, Lake Okeechobee overflows, releasing water into a slow moving, shallow river. The river is mostly saw-grass marsh. The Everglades is an ecosystem that hosts a large diversity…
in the functions of an ecosystem. Alligators are one of the keystone species in a freshwater swap.
Alligators are a keystone species in the freshwater marshes due to the burrows they create to nest and keep warm which then fill with water and provide breeding and drinking for other organisms.
Habitat: Alligators reside in freshwater swaps and marshes
Nutrition: Large adult alligators can eat all aquatic and terrestrial prey. Smaller alligators eat turtles, fish, small mammals,…
Turtles are reptiles of the order Chelonii or Testudines characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield. Turtle may refer to the chelonian order as a whole (American English) or to fresh-water and sea-dwelling chelonians (British English).
The order Chelonii or Testudines includes both extant (living) and extinct species. The earliest known turtles date from 220 million years ago, making turtles one of the oldest reptile groups…
Baird’s Tapirs may stand four feet tall at shoulder length. Baird’s Tapirs average up to 6.6 feet in length and 3.9 ft. in height, and adults weigh 180–880 lb. Baird’s Tapir has a unique cream-colored marking on its face and throat with a dark spot on each cheek. The same dark spot is also behind and below the eye. The rest of its hair is dark brown or grayish-brown. Young Baird’s Tapirs have a pattern of yellow or white stripes and spots that look…

A bogeyman (also spelled bogieman, or boogeyman) is a mythical creature in many cultures used by adults to frighten children into compliant behaviour. The monster has no specific appearance, and conceptions about it can vary drastically from household to household within the same community; in many cases, he has no set appearance in the mind of an adult or child, but is simply a non-specific embodiment of terror. Parents may tell their children that if they misbehave, the bogeyman will get them.…
