Animales complejos: resumiendo

The video explores the fascinating traits of complex animals, starting with fish, which have gills and are ectothermic. It then discusses amphibians, which live in water initially and later on land, and reptiles, which can live entirely on land due to their scales and thick skin. The video also covers birds and mammals, both of which are endothermic. Birds have wings and feathers, while mammals are advanced vertebrates with hair or skin, live births, and developed brains. The video concludes by encouraging viewers to reflect on these traits when observing animals.
