Creature Features: Dolphins and Porpoises

Dolphins and porpoises are closely related but they aren't the same! Both belong to the scientific suborder, Odontoceti, which means "toothed whales," but they have different families. Dolphins are part of the Delphinidae family while porpoises are members of the Phocoenidae family. Very scientific sounding, huh? I'll bet you know more about dolphins and porpoises than you think – test your knowledge about these marine mammals in a quiz!

For the 4th question... Male killer whales often do get larger than 23 ft. I got the first one wrong though - I wouldn't call you guys a "pig fish," little porpoises!! ;)
