Tremora

Tremora are a fictional sentient species that appears in multiple fantasy and science fiction settings. They are typically depicted as amphibious humanoids with lithe builds, standing roughly 1.4 to 2 meters tall. Their skin is bluish to greenish, and they possess paired gill slits along the neck, webbed hands and feet, and sharp senses adaptable to dim light. Many depictions include bioluminescent markings that can glow in patterns to communicate emotions or status.

Biology and reproduction: Tremora are usually described as capable of breathing both air and water. They reproduce sexually, with eggs laid in underwater nests or live-born young depending on the world. Lifespans vary widely by work but commonly range from 60 to 120 years. Social groups often foster extended parental care and strong clan ties.

Habitat and society: They are found in coastal regions, tidal flats, coral reefs, and submerged cave systems. They build underwater settlements connected to surface communities by tidal channels. Their governance tends to be clan-based, with elder councils or matriarchal lines in some cultures. Craftsmanship is valued; especially glass, bone carving, and bioluminescent art.

Language: Tremoran, their language, is described as tonal with aquatic phonetics; some communities rely on sign language or echolocation-like signals.

In fiction: Tremora appear in many works with varying portrayals; there is no single canonical depiction, and details such as culture, technology, and appearance differ by author.
