Akwin

Akwin are a race of sapient, carnivorous, aquatic creatures native to the oceans of planet Lazerian IV. They have a long neck and three pairs of limbs: the first pair ending in tridactyl hands, the middle pair ending in long flippers and the last pair ending in webbed feet that can be used to walk on land, although Akwin spend most of their time in their underwater cities. Their skin is bluish-green and they have some sort of hair on their heads, which can be blue or black colored. Their tail ends in flukes, similar to a Dolphin's. They are able to breathe both underwater and on land.

The Humans living on the surface of the planet are not aware that the Akwin civilization actually exists, believing it to be just a legend.
