Dolphins The largest of all dolphin species is the Orca, which is commonly known as the Killer Whale. These dolphins can be over 31 feet long when fully grown, which has provided them with the un proper name of “whale”. Also, there are several different dolphins considered as the smallest dolphin species. These include True dolphins, Tucuxi dolphins, Hector’s dolphins, Black dolphins, River dolphins, porpoises, and Commerson’s dolphins.
