Reptilia

Reptiles are a diverse group of cold-blooded vertebrates characterized by scales, external fertilization, and typically laying amniotic eggs. They include snakes, lizards, turtles, and crocodiles. Reptiles are well-adapted to various environments and often exhibit scaly skin, providing protection and reducing water loss. Their cold-blooded nature means they rely on external sources for temperature regulation. Reptiles play essential roles in ecosystems, contributing to biodiversity and ecological balance.
