Pomacanthus

Part of speech: noun

Definitions

1. A genus of angelfish found in tropical and subtropical seas, known for their bright colors and large rounded bodies
2. A group of marine fish belonging to the family Pomacanthidae, characterized by vibrant coloration and flattened disc-like shapes
3. A taxonomic genus of ocean-dwelling angelfish distinguished by their elaborate patterns and substantial size relative to other reef fish

Etymology: Ancient Greek "pōma" meant a lid or cover, and "akantha" meant a thorn or spine. Taxonomists combined them to name this genus of marine angelfish, so the name is a modern scientific coinage rather than a classical Greek term. The roots describe a specific anatomical feature. Fish in this genus have a strong spine on the edge of the gill cover, the flap of bone that protects the gills, and the name points to that spine.
