[Coral-List] Cetaceans-ID help

[Steve Mussman]

Had an interesting encounter with a large pod
of whales/dolphins recently while diving in Cozumel.
I'm not sure about the identity of the species 
and I was hoping to get some help. I originally
thought they were pilot whales, but after
some research, it appears more likely that 
they were false killer whales (?) I'm also 
assuming that they were not all the same species,
but that may have been based on a distorted view
from a different angle or the age of the individual 
specimen. Any help identifying them would be greatly 
appreciated. 

Here's a link to some of the photos I managed to get;
