Common name: Snakelocks anemone

Scientific name: Anemonia viridis (Forskål, 1775)

General information

The Snakelocks Anemone, Anemonia viridis, is a distinctive sea anemone found in the shallow waters of the Mediterranean Sea and parts of the Atlantic Ocean. It is known for its long, sinuous tentacles that resemble locks of hair, which are often a vibrant green due to the presence of symbiotic algae known as zooxanthellae. These algae provide the anemone with additional nutrients through photosynthesis, which is why Anemonia viridis thrives in well-lit environments.

Care

In the aquarium, Snakelocks Anemones require stable water conditions with moderate to high lighting to support their symbiotic algae. They prefer rocky substrates where they can anchor their base. Care should be taken to ensure that they are not placed too close to other corals or anemones, as they can be aggressive and may sting their neighbors.

Reproduction

Anemonia viridis can reproduce both sexually and asexually. In the wild, they release gametes into the water column for external fertilization. Asexually, they can also reproduce through pedal laceration, where small pieces of the base detach and develop into new individuals.

Symbiosis

This anemone is well-known for its symbiotic relationship with various species of clownfish, particularly the @species:amphiprion-ocellaris. The clownfish are protected from predators by the anemone's stinging cells, and in return, they provide the anemone with nutrients from their waste and help with water circulation.

Habitat

Anemonia viridis is commonly found in shallow, rocky areas, often attaching to the underside of boulders or in crevices. They are adapted to a range of light conditions but do require some level of illumination to maintain their symbiotic algae. Their distribution includes the Mediterranean Sea and adjacent Atlantic coasts, extending to the British Isles.
