Snakelocks anemone
species of cnidarian sea anemone
The snakelocks anemone (Anemonia viridis) is a sea anemone found in the eastern Atlantic Ocean and the Mediterranean Sea. The latter population is however sometimes considered a separate species, the Mediterranean snakelocks anemone (A. sulcata).
The tentacles are usually a deep green color with purple tips. The green color is often attributed to the presence of symbiotic algae within the tentacles but is the result of the presence of green fluorescent protein which is present in corals, sea anemones, and some other cnidarians. The anemone tissue contains a symbiotic algae called zooxanthellae, which is necessary for the long-term survival of the sea anemone. When the numbers of algae diminish the anemone may appear dull grey. The algae need light to flourish, so snakelock anemones will be found in the sunniest pools. On average the snakelocks anemone is 8 cm wide.
Reproduction
Unlike other cnidarians, anemones (and other Anthozoa) entirely lack the free-swimming medusa stage of the life cycle; the polyp produces eggs and sperm, and the fertilized egg develops into a planula that develops directly into another polyp.
Ecology
Several species of small animals regularly live in a symbiotic or commensal relationship with the snakelocks anemone, gaining protection from predators by residing among the venomous tentacles.
This brief starts where responsible research should: with the source description of “Snakelocks anemone” as species of cnidarian sea anemone. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as species of cnidarian sea anemone. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q1192992. None of the 0 selected statements returned an explicit reference.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
