Nyukeleus

The Nyukeleus was a sea Rahi species which dwelled in the Pit. Due to extensive hunting, most Nyukeleus have died out by now, although several lone specimen remain alive at great depth.

Physique
The Nyukeleus is a Rahi of stocky, highly hydrodynamical build. Two clawed arm-like extensions, which are used to grab prey, and a likewise clawed tail jut out of its back. It is reasonable to suppose all of these were created by the Pit Mutagen. The latter also blinded the Nyukeleus, but granted it sonar abilities instead.

Hunting habits Nyukeleus2.JPG
Using its sonar abilities, the Nyukeleus detects and tracks down prey in a radius of two kio. It is, in opposite to most mutated Pit Rahi, not bioluminescent, for it does not need to bait prey, being an active hunter. The Nyukeleus usually eats smaller sea Rahi, but does not fear the like of the Takea sharks either. Some have even been known to attack the Mahri Nui Matoran.

Habitat
Dwelling deep in the Pit's Black Water, the Nyukeleus likes to stay in darkness, as it does not need light to live. After the Mahri Nui Matoran started to hunt it, a few specimen emigrated and survived to this day, much to the fear of Matoran fishermen.
