Cursed sea devil
A deep sea fish native to Otra IV, the cursed sea devil displays sexual dimorphism, with the female being a large, gelatinous lump of a creature with a large head full of long glassy fangs and a bioluminescent lure on ots head. She has an expandable stomach, allowing her to swallow even very large prey. The males are tiny, toothless and parasitic, with large eyes and nostrils they use to find a mate and fuse into her body, becoming little more than a vessel for sexual reproduction.
