Wolphins are interesting hybrids with a misleading name.
There are a few members of the dolphin family with "whale" in their name that can hybridize with other dolphin species.
But while the offspring are called "wolphins," they're dolphin hybrids rather than crosses between a giant baleen whale and a dolphin, as the name might suggest.
The first hybrid to carry the wolphin name was the offspring of a false killer whale (Pseudorca crassidens) and an Atlantic bottlenose dolphin (Tursiops truncatus) at Sea Life Park Hawaii.
Since then, humans have bred a number of other dolphin hybrids in captivity, and very occasionally, wild populations also produce them.
