Purple Sea Anemone

Halcampoides purpureus

The Purple Sea Anemone, belonging to the family Halcampoididae, can be found in various regions including the Eastern Pacific, Antarctic, and the Mediterranean. It is commonly recorded in areas such as Alaska, USA, Canada, and the Kerguelen Islands. This anemone inhabits depths ranging from 8 to 183 meters, with most sightings occurring at shallower depths of less than 40 meters. It prefers environments like coarse sand near Posidonia meadows, crevices between rocks, and small caves. During the day, it remains buried in the sand, emerging at night to feed, showcasing its nocturnal behavior. The Purple Sea Anemone is a solitary creature, often seen alone rather than in groups. It is sessile, meaning it remains attached to a single spot rather than moving around. Reproduction in this species involves the release of mature gametes into the coelenteron, which are then spawned through the mouth. The resulting zygote develops into a planktonic planula larva before settling down and undergoing metamorphosis. Divers encountering this anemone may find it nestled in sandy or rocky crevices, often partially buried. Its nocturnal nature means that night dives might provide the best opportunity to observe it fully extended.
