What family are dolphins and whales in?

Are dolphins and porpoises in the same family?

In fact, as the Encyclopedia of Marine Mammals points out, porpoises and dolphins are “as different as horses and cows or cats and dogs”. Porpoises belong to the Phocoenidae family.

Are orcas dolphins or whale?
While orcas are members of the marine dolphin family Delphinidae, their overall size is what sets them apart from others in their suborder. Today, if a dolphin reaches a size of more than 30 feet long, it may be referred to by some as a whale, but the rules of taxonomy still classify the orca as a dolphin.
Were dolphins land animals?
