Harbor porpoises are small, toothed marine mammals, often mistaken for dolphins. Unlike dolphins, they have a more triangular dorsal fin and a stockier body. They prefer coastal waters and harbors, hence the name. Think of them as the shy, quiet cousins of the more flamboyant dolphins. They are generally less social than dolphins, often seen alone or in small groups. Their diet consists mainly of small fish, squid, and crustaceans. Sadly, they face threats like entanglement in fishing gear and habitat degradation.
