Creature Profile - Zebra Dolphin

Completed an unfinished drawing from 2 years ago. This is a profile of my fun imaginary creature I created, a zebra that sort of evolved into a dolphin-like sea mammal to escape land predators. It has a long, whip-like tail and powerful front flippers that allow it to swim faster than a dolphin. It still has a little hair on the end of its tail and a short bristly crest on its back, showing its land-based origin. Don't you want one for a pet? It has two alternate names, a 'zolphin' and a 'dobra'. Feel free to help me come up with another name for this animal!
