fig. 1: Tai Haku is kicking himself this is blank space and not an awesome eagle ray and/or shark photo.
To try and make up for this here are some old photos, topside but of a very interesting sea beasty.
These are Risso's dolphin, Grampus griseus, which for literature fans amongst you is the origin of the phrase "puffing like a grampus". This was a huge pod of Risso's, that's a juvenile at the bottom right. Risso's are a weird dolphin - funny coloured, beakless, pretty big. Heaven knows what this big pod was up to.
Note the baby is darker, smoother grey whereas the adults are mottled and much lighter - this image shows this strange colour scheme better.
This image is the best I have of the Risso's melon-headed, beakless face. Risso's weren't the only dolphins in the region though, that's a common dolphin in front I believe.
