Nile crocodile (Africa, Madagascar)
With all crocodilians, the gender of the young is determined by temperature. Nests with a temperature less than or equal to 30° produce females, those around 31° produce young of either sex, and those with a temperature of more than 32° produce males. The Nile crocodile is the most common crocodilian in Africa. It regularly exceeds 4 meters in length.

There are more than 3,400 snake species. Boa constrictors belong to the Boidae family. They are non-venomous, instead suffocating their prey by rolling themselves around them, then swallowing them. Females keep eggs in their genital tracts until they hatch and give birth to fully formed young.
