The most realistic name for a dolphin. Based on the fact that dolphins are complete and utter cunts who know something that we don't but are clever enough to let us know they know something without actually telling us.
In land terms the only thing as cunty as a dolphin is Teddy Sheringham, ex-Spurs footballer.
Dolphins are the Sheringhams of the water, therefore 'Water Sheringhams'.
Look at that Bottlenosed Water Sheringham herding that unfortunate swimmer out to sea where they will be eaten by sharks.
How can we sink that enemy submarine? I know, let's strap a bomb to a Water Sheringham and teach it to explode when they get close enough.
