The algae need light to flourish, so snakelock anemones will be found in the sunniest pools.

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.

[citation needed] 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.

These include the incognito (or anemone) goby (Gobius incognitus),[3] the shrimp Periclimenes aegylios and the Leach's spider crab (Inachus phalangium).

The whole animal is marinated in vinegar, coated in a tempura-like batter, and deep-fried in olive oil.
