AI overview
Porpoises are small toothed whales that look similar to dolphins but are actually more closely related to narwhals and belugas, and can be distinguished from dolphins by their flat, spade-shaped teeth and lack of a pronounced beak. There are eight species of porpoises alive today, making them among the smallest of all toothed whales.
