In their research using American alligators, they found that a thermosensitive protein called TRPV4 is present within the developing alligator gonad inside the egg. In these reptiles, the temperature of the eggs during a certain period of development is the deciding factor in determining sex, and small changes in temperature can cause dramatic changes in the sex ratio Bull Spencer and Janzen found that hatchlings from mixed-sex nests were less energy efficient and grew less than their same-sex counterparts incubated temperature dependent sex determination in crocodiles nightclub in Florida single-sex producing temperatures.

InConstantine Samuel Rafinesque postulated that the species was in fact a crocodile. Her current work attempts to estimate variation in recombination and hybridization in a comparative genomics context and identify parts of the genome where hybridization is restricted between species.
While the sex of most snakes and most lizards is determined by sex chromosomes temperature dependent sex determination in crocodiles nightclub in Florida the time of fertilization, the sex of most turtles and all species of crocodiles is determined by the environment after fertilization. Mystery of the Lost Colony of Roanoke 'is over': Writings and remains reveal 'vanished' English settlers An estimated 1, to 2, American crocodiles live in Mexico, Central America and South America, but population data is limited.
