Porpoises, along with whales and dolphins, are descendants of land-living mammals, most likely of the Artiodactyl order.
The porpoises are small cetaceans of the family Phocoenidae; they are related to whales and dolphins. They are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible difference between the two groups is that porpoises have spatulate (flattened) teeth distinct from the conical teeth of dolphins. In addition, porpoises are relatively r-selected compared with dolphins: that is, they rear more young more quickly than dolphins.
Porpoises, divided into six species, live in all oceans, mostly near the shore. Probably best known is the Harbour Porpoise, which can be found across the Northern Hemisphere.
They are Mammals.

Really enjoy the taste of Pickerel/Walleye. I grew up in Northern Ontario, Canada on Lake of the Woods a big tourism area known for great fishing. Really lots of picerel to catch and eat there, it's such a mild sweet flavoured fish when it is fried for a nice shore lunch after fishing all morning! :) God's country with wonderful food!

A mammal. It's a cetacean, closely related to dolphins.
