Dolphin
A smaller cetacean; mammalian ocean life nearer the surface than whale.
description
A dolphin is a cetacean: warm blood, milk, bone, and a body shaped by water. It is nearer the surface than a whale, and still the same return of a mammal to the sea.
Dolphin is not a type. It feeds Whale first, then Water. The card keeps the deep mammal; the map keeps this cousin.
