Description

This species of sea anemone has a maximum diameter of 5 mm (0.20 in) and maximum length of 7 cm (2.8 in);[5] it is similar to Edwardsia claparedii but even more elongate, with a translucent pale orange colour. It has 16–32 tentacles arranged in 3 cycles, with 4 larger tentacles in the primary cycle.[6] Its column is slender, without tubercles. It has cinclides (pores in the body wall for release of water and cnidocytes).[7][8]

Range

Edwardsia timida is found in the Irish Sea and English Channel.[9] It is one of 943 species listed by Natural England in 2014 as species of principal importance for the conservation of biodiversity in England.[10]

Habitat

Edwardsia timida burrows in sand or gravel from lower shore to shallow sublittoral.[11][12]
