Porpoise Dolphin Species

There are a few different porpoise dolphin species.

They are relatively small cetaceans, generally measuring up to 2m long and weighing up to 200kg, but often less than 100kg.

They often live in coastal waters and swamps, estuaries, bays and coastal rivers. Most of them are slow swimmers, travel in small groups, and don't tend to follow boats, as do many oceanic dolphins.

Physiological features include at least 11 pairs of teeth, and small flippers. Although they are often called dolphins, they differ from real dolphins by having flattened teeth and no beak. They also have a more rounded head than real dolphins.
