Croatobranchus mestrovi

…a highly unusual species of troglobitic leech that is endemic to caves in Northern Velebit, Croatia. Little is known about C.mestorvi’s biology but it is know that is is highly adapted to its troglobitic lifestyle. Its body is very flat and has ten pairs of finger-like projections, which are probably gills. Its diet is unknown but individuals are known to cling to walls facing water streams, while twisting its body as if it was trying to capture something.

Kinabalu Giant Red Leech (Mimobdella buettikoferi)

…is a large species of leech that is only found on Mount Kinabalu in Borneo. This leech species is not a bloodsucker, but is instead a hunter and feeds only on worms, like the Kinabalu giant earthworm (Pheretima darnleinsis). This leech is poorly researched and not too much is known about its biology.
