I personally think the great white shark should really be coastal/pelagic and the whale shark pelagic. A giant squid would so deeply dissapoint me (and a lot of other people, as Steve said), and it would DEFINATELY not be in pelagic. Benthic or nothing. i say the whole benthic biome and goblin shark shouldn't have been included, and instead a marine iguana for coastal.
I'm making a wishlist agin, aren't I? Oh well.
Overall, I think this is one covered MOST of the marine animals people wanted. I don't care if the pilot whale and beluga look similar - no offence, but does anyone complain about non-meshed user made downloads?
