Bone marrow worms are small parasites that look like a mixture between some sort of twisted insect and an inch worm, with a sharp thorny protrusion on their head. They have six sharp pointed legs which they use to grasp onto their target, and then burrow themselves headfirst into its flesh. Once they have started burrowing into the flesh of their host, they lift their scales which creates tiny barbs that make removing them extremely difficult and painful. Once the bone marrow worm finds a suitable bone it will begin boring into it with its sharp head spike. This may take hours or even days and is excruciating. Once inside it will begin laying eggs which hatch within 3 days. The parasites will continue to breed, devour, and consume until the host is dead, at which time they remove themselves from the host body and go in search of another.
