Reptiles
Amphibians       Birds      Fish       Invertebrates       Mammals       Reptiles

The first reptiles appeared approximately 315 million years ago. They were ectothermic (cold-blooded) and shared some superficial similarities to the amphibians who ruled the land at that time, but reptiles use their lungs to breathe from birth, possess watertight scale or scute-covered skin, and lay hard-shelled eggs which allows them to spend their entire lives on land. Reptiles became so successful during the Mesozoic era (about 252 to 66 million years ago), it was dubbed the “Age of the Dinosaurs,” a time that has inspired many a young paleontologist! Reptiles are still plentiful today, with many types of crocodiles, lizards, and snakes serving as representatives.

Interesting Facts

For years, the Komodo dragon was accused of having a mouth so filthy that even if you escaped its terrible bite, you were doomed to eventually die from the ensuing bacterial infection. However, recent studies on Komodo dragons demonstrated that this was unfair, as they have mouths cleaner than many mammalian carnivores. It turns out the reality is worse than the myth: they have poison glands! Komodo dragons produce a venom that sends prey into shock while keeping its blood from clotting. A deer or pig who “escapes” will run off and go into shock, and bleed out from its wounds within 3 hours, leaving an easy treat for the dragon.
