Dolphins and Porpoises
The smaller cetaceans, popularly known as dolphins and porpoises, compose this family. Properly speaking, the name dolphin belongs to those species which have a projecting snout, while porpoise refers to those with uniformly rounded head. With their usual perversity, however, our earliest settlers christened the commonest of these animals on our Atlantic Coast the "porpoise," while in reality it is a true dolphin, the same as the "bottle-nose" of the coasts of Europe.
