I was walking the OC boardwalk tonight with the wife on the way to get something to eat for dinner. Something caught my attention in the water and I said to my wife "What is that". And as soon as she looked over, something with a black back and a white bottom (orca like) jumped out of the water and did nice spin and dive. Looked like a BIG porpoise. I have seen many gray ones playing in the OC surf, but not one that was so clearly Black and white. Is this a different species? Then again, maybe it was Orca baby.
