The Bludroth is a modern Subspecies of Ludroth that inhabits Desert Caves. It has a large, blue, and agile fin on it's back, used too ward off heat and navigate under desert sand, and in water-filled caves. The blue color of their skin comes from the fish they eat and the minerals that gather on it.
They are closely related to Ludroth, and can be killed in much the same wayy.
It tends to live in large water-filled caves in Deserts, able to survive for long periods of time under sand. They may also Live in Swamps, though this is rare.
They act in much the same way as ludroth, with an exception: they may swim under a hunter within the sand, and leap up, impaling anyone careless enough to not move.
