Crocodile Sex

Did you know, depending on the temps in the first 25 days of the egg, one can make males or females? How awesome is that. Is this true for snakes?

Not any snakes that I know of, but some lizards including leopard geckos are temp incubated for sex. You can choose to make all females, all males or both with any clutch you want.

Crocs are very interesting creatures.....know this is off the original posters topic but didn't think it was worthy of its own thread.

just found out the other day that crocodiles increase their density by swallowing stones. (Remember density=mass/volume) 4-5 kg of stones have been found in the front stomach of large crocs. The increased density allows crocs to swim lower in the water and expose less of themselves to potential prey.

The stones also aid in digestion....since crocs don't really chew their food!

Turtles, Tortoises and many lizards are the same.
