Sewage Dylanus

Sewage dylanus is a formerly fictional species of future descendant of feral dylanuses that originated from the urban future series.

Description
Sewage dylanuses are found throughout sewer systems of the urban future. Unlike their ancestors, they are fully carnivorous as there aren't much plant food around the sewers across the world. They mainly feed on sewer rats, other smaller mammals, and small reptiles. They are about the size of the extinct American killer dylanus, not as large as their feral dylanus ancestors due to its main food sources being scare or disperse in its native ranges. They have long witch-like hands to snatch up their prey, they also have no pigments (making them have gray skins) and no eyes, so they rely on their newly-evolved melon organs, similar to that of modern toothed whales, to find their ways in the dark. They also have large ears to hear their ways in the dark, and their ears have water-proof membranes to keep their inner ears dry and yet thin enough for them to hear well. They have webbed feet that can splay out to help them swim more effeciently than their ancestors. They are completely tame and nonaggressive towards occasional sewer workers who travel in sewer systems.
