Wholphin
Though the name sounds like the twisted pronunciation of a toddler for a dolphin, this is actually the name of our hybrid, which happens to be a cross between two species of dolphins. The wholphin is a product of a false killer whale (a type of dolphin) mating with a bottlenose dolphin. This is a rare hybrid to occur despite both its parents sharing the oceans.
There have been reports of wholphin sightings in the wild but per the official records, there exist only two of them in the world, both at Sea Life Park in Hawaii. In terms of their teeth, these offsprings of false killer whales and bottlenose dolphins lose in numbers. The bottlenose has a whopping 88 teeth, the false killer whales 66, and yet the wholphins have only 44 teeth in total.
