Alligators, caimans, and gharials lived in the Gulf of Mexico and stayed within the egg-laying branch of the family. The new study, published online today (Jan. 19) by the journal Science Advances, is the first to show that crocodiles and alligator-like reptiles are closely related to each other. The study also shows that the crocodile-alligator family tree is more complex than previously thought.

Do alligators lay eggs or give live birth?
Seven to 10 feet in diameter and two to three feet high can be found in the nest. Around late june and early july, the female lays 35 to 50 eggs. Some females can lay up to 90 eggs. After a 65 day period, the eggs are covered with vegetation and hatch.
Can crocodile lay eggs without a male?
“The albino crocodile called Gori laid eggs without mating with any male crocodile. The biology of reptiles shows grown up female crocodiles rarely lay infertile eggs during the breeding season. “Gori is the first known case of a female croc laying an egg without a male in the wild.
Does crocodile lay egg in water?
Crocodiles lay eggs, which are laid in either holes or mound nests, depending on species. A hole nest is usually excavated in sand while a mound nest is constructed out of vegetation. The periods range from a few weeks up to several months.
The eggs hatch in about a week, and the young crocodiles leave the nest to forage for food. The young will stay with their mother until they are about two years old, at which time they will begin to explore the world around them.

They will stay with their mother until they are about 2-3 months old, at which time they will begin to explore the world around them.
Can crocodile change gender?
“Crocodiles are the only animals in the animal kingdom that can produce offspring that are genetically identical to their parents,” said study co-author and University of California, Davis, professor of integrative biology and anatomy, Dr. Richard Wrangham, in a statement.
