A marine animal with gills that have a radial or ray-like structure, particularly referring to certain mollusks.
From Greek aktis (ray) plus branchia (gill), describing gills that spread out like rays from a central point.
The name perfectly describes what these creatures look like under a microscope—their gills fan out in beautiful radiating patterns, like tiny fireworks made of breathing organs.
