Pelager

Pelagers are a type of creature which feature in Games Workshop’s Warhammer 40,000 setting.

Overview
Other than the fact that Pelagers are a type of Abhuman specifically adapted to survival on oceanic worlds, little is known of them. They have, however, been acknowledged by the Imperium of Man, an organisation specifically noted to be xenophobic in the extreme, to be a recognised, stable and acceptable strain of Abhuman, a creature which has not deviated so far from the human genetic code to preclude its inclusion in the list of biological offshoots.

Some Imperial biologists have theorised in recent years that Pelagers possess environmental adaptations such as low-light vision, hairless bodies, webbing between the toes and feet, enhanced lung capacity, and even rudimentary gills, but without further study on actual specimens, no one can be sure how these creatures have survived in such places. It may even be that Pelagers have lived in self-contained undersea cities, with their only adaptation being that of physiques adapted to enormous levels of air pressure.
