Remarks | Commonly found in estuaries and tidal swimming pools (Ref. 866). Known from depths of 0 to 30 m (Ref. 7727). It is known to secrete purple ink which is produced from the purple gland, speculated to be a defensive decoy (Ref. 81111). The ink may also be a metabolic by-product in response to eating algae, particularly red algae, as observed with the species under the genus Aplysia (Ref. 81114). Primarily feeds on cyanophytes and diatom mats and films found on sand, mud and other benthic substrata; facultatively it consumes Ectocarpus and Enteromorpha spp. (Ref. 81111). |
