Description:
Boloceroides spp. are looking like an untidy mop, this anemone is sometimes seen in sea grass areas on many of our shores. It is possibly seasonal. Sometimes, large numbers are seen (up to 10-20 animals in a trip) and then none at all. Tiny swimming anemones may sometimes be confused with Sea grass anemones which have translucent tentacles with tiny spots. The swimming anemone harbors symbiotic single-celled algae (zooxanthellae). The algae undergo photosynthesis to produce food from sunlight. The food produced is shared with the sea anemone, which in return provides the algae with shelter and minerals. The oral disk and tentacle muscles are used to obtain, retain, and ingest prey; in Boloceroides spp. tentacles can autotomize if it is needed to evade a predator. Tentacles can control body form by use of their endodermal muscles. Retractors are longitudinal muscles that will aid in withdrawing tentacles and the oral disk if they are exposed to the open air. This hypothesis is furthered because in comparison to other sea anemones, Boloceroides is loosely attached to its respective substrate, thus allowing the pedal disk to detach quickly resulting in a rapid swimming response. Boloceroides can reproduce both sexually and asexually. As Anthozoans, Boloceroides produce sexually by bypassing the medusa life cycle stage; this allows Boloceroides (and all Anthozoans) to release their egg and sperm creating planula a bilaterally symmetrical, flattened, ciliated, motile larva.
