Complex Animals Review

The video explores the fascinating features of complex animals, starting with fishes, which have gills and are ectotherms. It then covers amphibians, which live in water early in life and on land as adults, and reptiles, which live entirely on land with scales to prevent drying out. Birds and mammals, both endotherms, are discussed next, highlighting birds' ability to fly and mammals' advanced traits like fur and live births. The video concludes by encouraging viewers to reflect on these characteristics when observing animals.
