Some speedy kai these are, they have been found in the backwaters under the Lush Depths in the Blossoming Trench, and many have made it to Pharloom. These can be found nearly anywhere there is water, but also almost anywhere with prey that they hate, and they absolutely love the rest of the kai family! These fellows hold grudges to their grave, but not to their fellow kai. They are actually a forager species, and may hold many large shrimp on their sharp beaks as shushkebabs (or however you spell that) for other kai.
There are still many in the Lush Backwaters, but a majority of them escaped to Pharloom from a leak into the pipes of the Putrified Ducts (UNarguably, worst area in the game).
