A marine cnidarian species characterized by its vibrant red coloration and robust body, commonly found in rocky intertidal zones of the Northeast Atlantic Ocean and Mediterranean Sea.
Rocky coastal areas, tide pools, and marine rocky substrates with depths ranging from 0-15 meters, typically in temperate marine environments with significant wave action and complex substrate structures.
Critical marine ecosystem engineer, providing habitat complexity, serving as prey and predator in coastal food webs, and contributing to biodiversity in intertidal and subtidal zones.
