Dolphin vs. Porpoise. Dolphins and porpoises are cetaceans â marine mammals â that are closely related to whales. Dolphins belong to the Delphinidae family and are up to 30 feet long. Porpoises, belonging to the Phocoenidae family, are smaller and stouter, with other anatomical differences. Though both animals are very intelligent, dolphins are deemed to be more social and live in larger, more stable groups.
Home âº How do whales, dolphins and porpoises communicate with each other? How do whales, dolphins and porpoises communicate with each other? Communication amongst whales and dolphins is achieved in several ways. They create sounds, make physical contact and use body language. Large whales can communicate over huge distances (across entire ocean basins) using very low frequencies. Dolphins and porpoises however, usually use higher frequencies, which limits the distance their sounds can travel. In general, dolphins make two kinds of sounds, âwhistlesâ and âclicksâ.
