Swimming Anemone

Boloceroides mcmurrichi

The Swimming anemone, belonging to the family Boloceroididae, is a unique marine species found primarily in the Indo-Pacific and Southwest Atlantic regions. Unlike many other anemones, it can be found on muddy shores, either attached to stones or shells or freely resting on the mud surface. This species is sessile, meaning it remains fixed in one place, and is commonly observed in shallow waters, with 90% of occurrences recorded at depths shallower than 30 meters. The life cycle of the Swimming anemone involves a transformation starting with the release of mature gametes into the coelenteron, which are then spawned through the mouth. The zygote develops into a planktonic planula larva, undergoing metamorphosis with the early development of tentacles, septa, and pharynx before settling on the aboral end. This process highlights its complex reproductive strategy, which can be either gonochoric or hermaphroditic.
