Are dolphins whales ? Dolphins and whales both belong to the same group of marine mammals called cetaceans, but they are not the same animal.
Dolphins are a type of cetacean that belong to the family Delphinidae, while whales are a larger type of cetacean that belong to different families, such as the baleen whales (Mysticeti) and the toothed whales (Odontoceti).
Dolphins are generally smaller than whales, with a sleek body shape and a long snout. They are known for their intelligence, social behavior, and acrobatic abilities.
There are over 40 different species of dolphins, including the common bottlenose dolphin, the spinner dolphin, and the killer whale (which is actually the largest species of dolphin).
Whales, on the other hand, come in a variety of sizes, from the massive blue whale (which is the largest animal on Earth) to the smaller pygmy sperm whale.
Whales have a more rounded body shape and lack the prominent snout that dolphins have. They are known for their songs, which are used for communication, and their long migrations between feeding and breeding grounds.
In summary, while dolphins and whales are both cetaceans and share some similarities, they are distinct animals with different characteristics and belong to different families within the cetacean group.
