Recent Activity. Administering estradiol at male-producing temperatures generates females that are physiologically identical to temperature-produced females. Proceedings of the Royal Society B. An Introduction to Behavioral Endocrinology.

Large females lay up to 90 eggs at a time, though small females deposit only a fraction of that. TSD may be advantageous and selected for in turtles, as embryo energy efficiency and hatchling size are optimized for each sex at single-sex incubation temperatures and are indicative of first-year survivorship.

If the snail is attached to a female, it will become male. Gilbert SF.

PLOS Biology. We are finally beginning to understand the mechanisms by which this masterpiece is created. While the sex of most snakes and most lizards is determined by sex chromosomes at the time of fertilization, the sex of most turtles and all species of crocodilians is determined by the environment after fertilization.

Often, the egg deposition location -- sunny or shady -- determines the temperatures of the nest, and therefore the sex of the embryos.
