Ecology and distribution. Amphipholis squamata is known from several substrata (under stones, amongst algal and bryozoan turfs, rockpool weeds and occasionally on sandy bottoms) from the intertidal to 1200 m. Current distribution records suggests that it is abundant in the Eastern Atlantic from Iceland along the European margin, Mediterranean Sea, West coast of Africa, West and East coast of South Africa and Madagascar (Alva & Vadon 1989). The taxonomy of this species is currently being investigated (S. Stöhr, per comm.). It is likely that this presumed cosmopolitan species will turn out to be a complex of cryptic species and that there will need to be a revision of its geographic distribution.
This species can switch from deposit feeding by collecting particles within its tube feet to suspension feeding via trapping detritus in mucus. In the Gulf of Cadiz it was the most common ophiuroid, recorded from 10 mud volcanoes and at three other sites in association to carbonate chimneys and crusts as well as cold-water corals (Fig. 7 D). Young, intermediate and adult stages were found together at the same localities. This species was found at depths from 350 to 1379 m which is its deepest known record.
