Porpoises don't have the pronounced beak that most, but not all dolphins have and they also have different shaped teeth. The biggest difference is size, with all species of porpoise being that much smaller than their dolphin cousins. Additionally, ALL baleen whales have two blowholes whereas toothed whales only have one.ĭifferences between a dolphin and a porpoise The main differences with porpoises are that they are usually smaller than other toothed whales and instead of cone-shaped teeth they have flat, spade-shaped teeth.Īs a general rule of thumb, baleen whales are larger and slower (except the fin whale which is known as the “greyhound of the sea”) than toothed whales. (2) Toothed whales (otherwise known as odontocetes and including all species of dolphin and porpoise) – which as you would expect, have teeth, and eat larger prey items, including at times, other marine mammals. (1) Baleen whales – these are the “great whales” and as their name suggests they all have baleen plates that are used to filter their food (which consists of plankton and small species of fish).
