Aquatic:

The Aquatics are a group of races that inhabit the vast oceans of Wysoom.
They have little in common other than all being able to breathe underwater
(and the Behemoths are actually air breathers which can simply hold their
breath for a long time) and being more deadly underwater than on land.

Despite the wide variety of forms and cultures, the Aquatic races are
able to maintain a Sea Council among themselves, sometimes mediated by
the Tortles.

The Aquatic races are the Behemoths, the Illex, the Homarids, the Kuroa 
and the Rusalka.
