I think a lot of people are confused about the difference between dolphins and porpoises. While whales, dolphins and porpoises are in the same scientific group, Cetacea, they are not

The vast similarities and differences between dolphins and porpoises are astounding, to the naked and untrained eye, most common people would be unable to distinguish one from the other; this is generally because they are related. However there are three main differences between dolphins and porpoises, that is, porpoises are divided in to six species and sub species, while dolphins are divided into 40 different main types, the average dolphin is generally longer than the average porpoise, and the most obvious visible difference between the two groups is that porpoises have flattened, spade-shaped teeth. Another difference is that there are more fused neck vertebrae in porpoises than in dolphins, which limits the range of mobility in the porpoise neck.

The difference between Dolphins and porpoises though porpoises belong to the family of dolphins, porpoises are found in Rivers like the Ganges etc but porpoises are found in seas. The porpoises become pet easily for they are more talkative than Dolphins.

People use the terms dolphins, porpoises, and whales to describe marine mammals belonging to the order Cetacea (from the Greek work ketos, large sea creature), and often use them interchangeably. The orca, or killer whale, for example, is actually the largest member of the dolphin family.

Dolphins are by far more prevalent than porpoises. Most scientists agree that there are 32 dolphin species (plus five closely related species of river dolphin) and only six porpoise species.

So whats the difference? It essentially comes down to their faces (who can forget Flippers famous grin?), their fins, and their figures. Dolphins tend to have prominent, elongated beaks and cone-shaped teeth, while porpoises have smaller mouths and spade-shaped teeth. The dolphins hooked or curved dorsal fin (the one in the middle of the animals back) also differs from the porpoises triangular dorsal fin. Generally speaking, dolphin bodies are leaner, and porpoises are portly.

Dolphins are also more talka ...more
