The alligators can live to be 50 years old. The population of American alligators increased after they were placed on the list of threatened species. This species is now listed as threatened under the Endangered Species Act.

Why did alligators go extinct?
Alligators are found in the wetlands of the southern United States. Close to extinction, the reptiles were hunted. Hunting was banned and their habitat was protected after they were listed.
What alligator went extinct?
Deinosuchus is an extinct species of alligatoroid crocodilian, related to modern alligators and caimans, that lived up to 73 million years ago. The genus name is derived from the Greek word δείνος (dēnōnos), meaning “alligator”, and the Latin word for “crocodile”, dactylos. The genus was first described in 1872 by the German paleontologist Ernst Haeckel, who named it after the crocodile he had seen in the Nile River in Egypt.
It was not until the early 20th century that the genus became known to the scientific community, when it was discovered that some of its fossils had been preserved in amber, which is a type of sedimentary rock that contains the fossilized remains of organisms that have lived for millions of years.
Is alligator The Last Dinosaur?
Birds and crocodilians are the only animals known to be able to breathe. In fact, crocodiles can breathe through their gills, which are located on the top of their heads.
This means that they can use the air in their lungs to help them breathe, but they don’t need to use their mouths to do so. They can also breathe from their nostrils, although this is not as common as it is with birds and other reptiles.
Did alligators survive dinosaurs?
These sizeable reptiles survived–even though other large reptiles did not. The dinosaurs were the only ones to survive the mass extinction event 65 million years ago. Frogs and salamanders survived the extinction that wiped out 90 percent of life on Earth.
All mammals, including humans, are descended from a single group of animals that lived in the Cretaceous period, 65 to 65.5 Ma. The extinction of the dinosaurs was the most devastating event in Earth’s history. It was followed by the asteroid impact that created the moon and the formation of our solar system.
Do crocodiles live in China?
Large crocodilians can be found in all of the species. Chinese alligators, also known as Yangtze alligators, live in just a small part of China. Crocodiles are carnivores, meaning that they eat meat. However, they are not omnivores and will eat a variety of different types of food, including fish, insects, fruits, nuts, seeds, roots, and tubers. Crocodiles will also eat small mammals such as rodents, birds, reptiles, amphibians, fish and amphibian eggs.
