Fact - All of the above animals belong to the class known as cetaceans. In fact, dolphins and porpoises are basically miniature whales.
There are some differences. Dolphins have beak shaped snouts
and pointed teeth. Porpoises are the smallest of the three and have short fat bodies, short teeth shaped like chisels, and blunt
snouts.
Whales are the largest of the three categories and may have baleen plates
rather than teeth.
Toothed whales include animals like dolphins and porpoises that can be as small as one meter in length to the large Sperm Whale which can reach 18 meters long.
Myth - Like nearly mammals, killer whales are warm-blooded, breathe air with lungs, give birth to young, breastfeed, and possess a form of hair or fur. Swimming up to fifty kilometers an hour, killer whales are the fastest mammals in the sea.
