Dolphins and whales are not classified as fish; they are marine mammals belonging to the order Cetacea. Unlike fish, which are cold-blooded and breathe through gills, dolphins and whales are warm-blooded, breathe air through lungs, and give live birth. They share common characteristics with mammals, such as having a layer of blubber for insulation and being social animals. Their aquatic lifestyle and similar habitats can sometimes lead to misconceptions about their classification.
