They possess a unique snout nose, and their fourth tooth of the bottom jaw will be noticeable if they close their mouth. The American crocodiles are considerably long; the adult crocodiles come with a length of 7 to 15 feet, while the young ones are 8 to 10 inches long. The adult crocodiles weigh around 150 to 450 pounds. The American crocodiles basically live in areas where there is a blend of fresh and salt water. The coastal wetlands and canals are their likely habitats. These animals feed on a variety of water species like the crabs, fish, water fouls and other small water mammals.These animals are considered to be less aggressive than their cousins in Africa and Australia and they are rarely seen by people.
The female crocodiles hatch eggs during the months of April or May, it’s the responsibility of the female to build the nest, and the components of the nest include loose dirt and other stuff. She builds the nest in a heap, close to the water’s edge.

The eyes, nose and the ears of this animal is positioned at the top of its head, and this arrangement lets the animal to be fully immersed in water. The crocodile also possesses a nictitating membrane, which helps to protect its eyes. The lachrymal glands help to clean the eyes of these animals with tears.
American Crocodiles usually creep along on their abdomen, but they also have the ability of walking high. Smaller animals can gallop, and even larger crocodiles are capable of startling bursts of rapidity. They can swim equally fast by moving their body and tail in a winding manner, but they can prolong this form of movement much longer.
They generally go underwater for only a couple of minutes, but will stay submerged for up to 30 minutes if defenseless, and if they remain inactive they can hold their breath for up to 2 hours. They have an ectothermic metabolism, so they can survive a long time between meals —but when they eat; they can eat up to half their body weight at a time.
