Snakelocks Anemone


Snakelocks Anemone
Habitat

The snakelocks anemone is present mainly in the intertidal zone (area of seabed between high and low tide marks), especially in pools from mid-tide downwards but not extending far into the sublittoral. It is present on the western coasts of Britain from Portsmouth all around to the west coast of Scotland, where it extends northwards to just south of Cape Wrath.

Zoo Diet

The anemone at Living Coasts are fed twice a day. This is mainly Artemia (brine shrimp) but also plankton and target fed mussel meat, krill and mysis. 

Wild Diet

Tissues contain zooxanthellae (symbiotic algae – giving the green colour to the anemone), which appears to be necessary for the long term survival of this sea anemone. They can ingest larger food items both dead and alive, e.g. small fish, just moulted prawns, but may show a preference for sea snails and sea slugs. 

Behaviour

Snakelocks anemones are sessile, meaning that they are attached to the seabed or other substrate. They can often be found in large groups in rockpools, but can be solitary in deeper water. 

Breeding

Off the British Isles, the snakelocks anemones breed from June to August. The sexes are separate. Sperms and eggs are released into the water where fertilization takes place. Eggs are provided with zooxanthellae. Reproduction can, and often does, take place by longitudinal fission, whereby the anemone divides in to two identical halves. This can take between five minutes and two hours.

Threats

There are no known major threats for this species. 

Conservation

No specific conservation measures are in place for this species but it may occur in protected areas.
