The ultimate vampiric mutation of predatory Ctenophora or "comb jellies" takes on a leathery, egg-like shape housing a bare-bones neural network just powerful enough to achieve psychic levitation. Rows of bioluminescent cilia have a hypnotic effect on intelligent prey, allowing the creature to drift liesurely over a victim's head and begin draining blood through dozens of hollow teeth. Its primitive eyespots can distinguish only light from dark, but its delicate tentacles can feel the pulse of other creatures from a great distance.

  When not engaging a prey animal or other enemy, Bloodbell collapse their bodies and slither in a sluglike fashion.
