Piscciss Volann

The aquatic alien species; Pisccis Volann is of the water planet Piscciss (a play on "pisces", Latin for fish). Volanns are not the biggest fish in the Pisccian Sea, but are definitely the most dangerous. Part alligator, part eel, and part leech, few can match the Volanns underwater. With their powerful tails and slimy scales, Volanns are capable of incredible speed and agility in the water. Volanns have huge mouths filled with rows of razor-sharp teeth that can chomp through almost anything, and their lower jaw unhinges to allow them to swallow objects in a single bite. Alternatively, Volanns can use their claw-tipped fins to rip their enemies to shreds. Volanns can also withstand a remarkable amount of pressure, and their luminescent danglers allow them to see in the darkest of depths. Being creatures of the sea, Volanns are useless on land, being unable to walk and only able to breathe for short periods at a time. Volanns must keep their gills wet or they'll dehydrate and die.
