Animales complejos: reptiles

The video introduces reptiles, a group of vertebrate animals distinct from amphibians, as they lay eggs on land and live entirely on land. Reptiles are ectothermic, have lungs, and possess hard, scaly skin that prevents dehydration. The video also covers the historical dominance of dinosaurs and the current diversity of approximately 7000 reptile species, including tortoises, crocodiles, lizards, and snakes. Some reptiles, like rattlesnakes, have venom to paralyze or kill prey.
