Ecology. Known to live in association with sea anemones: Actinoporus elegans Duchassaing, 1850, Bartholomea annulata (Lesueur, 1817), B. granulifer (Lesueur, 1817), C. gigantea, Homostichanthus duerdeni Carlgren, 1900, L. neglecta, L. lucida; with S. helianthus as preferred host (Silbiger & Childress 2008; De Grave & Anker 2017; Brooker et al. 2019). Occasionally found in association with the stony corals D. cylindrus (cf. Brinkmann & Fransen 2016) and Mussa angulosa (Pallas, 1766) (García-Hernández & Schizas 2021), the corallimorpharian Ricordea florida Duchassaing & Michelotti, 1860 (Ritson-Williams & Paul 2007), on the gorgonian E. tourneforti Milne- Edwards & Haime, 1857 (Criales 1980) and on the sea slug Elysia crispata Mörch, 1863 (Hoeksema & Fransen 2017). Herein for the first time recorded from the stony coral M. meandrites.
Distribution. Widely distributed in shallow waters of the tropical western Atlantic; usually in depth between 0 and 5 m, rarer in depths to 20 m (De Grave & Anker 2017).
