What is the difference between a porous and a dolphin?

Answer 1

I think you want to know the difference between a porpoises and a dolphin. (If that is the case, then consider my answer but if not then never mind. )

>>Porpoises have spatulate (spade-shaped or flattened) teeth distinct from the conical teeth of dolphins.
>>Porpoises are relatively r-selected compared with dolphins: that is, they rear more young more quickly than dolphins.
>>Porpoises tend to be smaller but stouter than dolphins.
>>Porpoise's dorsal fin is generally triangular, rather than falcate (curved) like that of many dolphins.
>> Porpoises tend to be less acrobatic and more wary than dolphins.
>>Porpoises are rarely held in captivity in zoos or oceanaria, as they are generally not as capable of adapting to tank life nor as easily trained as dolphins.
>>Porpoises belong to the Family Delphinidae, while dolphins belong to the Family Phocoenidae.
>>extended beak present in most dolphins is absent in most porpoises.
>>Porpoises lack a melon, while the bulbous forehead is often observed in dolphins.
>>Porpoises are rarely observed in groups of more than one or two individuals, in contrast of the dolphins.
>>Dolphins can be observed bow-riding, or riding on the pressure wave of a large ship or whale, on passing vessels. Unlike dolphins, porpoises are rarely seen bow-riding.♥
