EELyah

EELyah is a fictional term used in contemporary speculative fiction to describe an aquatic, eel-like humanoid species. The name appears in fan works and some indie game and novel projects, though it lacks a single official canon. In these depictions, EELyah are beings adapted to life in dark, high-pressure marine environments.

Biology and morphology: They typically have elongated, serpentine bodies with smooth skin, reduced limbs, and large eyes or photoreceptors suited for low light. Many portrayals include bioluminescent markings along the torso and head, which serve social signaling and camouflage. They are usually portrayed as possessing heightened electroreception and sensitivity to underwater sound.

Habitat and ecology: They are described as living in deep-sea trenches, subterranean caves, or submerged canyon systems, often in communities organized around resource-rich hydrothermal vents or bioluminescent flora. Diet is typically small fish, plankton, and mineral deposits.

Society and culture: Social structures vary; some works present EELyah as nomadic collectives that trade luminous resources, while others present settled clans with ritual sites. Language is imagined as a combination of bioluminescent signaling and subvocal clicks or ultrasonic vocalizations.

In media: The term has appeared in various fan communities, role-playing games, and indie storytelling projects. It is not part of a recognized, formal universe.
