Silt Centipede

Dangerous creatures that congregate along common routes through the Silt Sea, feasting mainly on non-indigenous life. It's predation relies mainly on surprise and mimicry, taking on the appearance of a dead human sinking into the silt when partially submerged. They are rare yet a known threat, the subject of many of superstitions and children's stories. The origin of the species is unknown, although experts theorize that they were only recently created through magical experiments, due to their historically unsustainable diet.

Description
Dorsally, it takes the appearance of sickenly pale and emaciated human, although when submerged several meters of length is hidden as well as the two dozen pairs of shoulders come long spider crab like legs that end in three fingered pincers. It's ventral side consists mainly of a gaping maw along its length, symmetrically lined on each side with near a hundred small legs used for grasping prey. On its head, a nest of over two dozen eyes hides below long black antenna that mimic a full head of hair when partially submerged.
