Umbraworm

Following the hellworms to the dark hot depths of the vents, it feeds on its relative. Its chemoreceptor antennae have evolved into toothy mandibles that grasp onto its prey and pull it to its radula-based mouth. It also will seek out carrion of any creatures that it finds. It has lost all pigmentation due to the lack of sunlight. While it still has eyes they too have weakened and only are there to pick up the faint light of the smoking vents which can sometimes help find its prey. Its chitin skeleton is thicker and helps protect it from the extreme heat and pressure.
