Carrion Stalker

Carrion Stalkers are one of the many hideous monsters native to the Ravenloft setting of Dungeons & Dragons. Resembling a cross between a horseshoe crab and a jellyfish, colored so that it looks like an exposed ribcage nestling over decaying entrails, they are a race of scavenging vermin, feeding on corpses and attacking living creatures that draw close in order to create more corpses upon which to feed and nurture their grubs. They may have been inspired by the Facehugger from the Alien movies.
