Ecology and distribution. Amphiura filiformis   is a common, predominantly shallow-water species of the north-Eastern Atlantic. It is known to occur from Norway to West Africa and also in the Mediterranean Sea at depths up to 1665 m ( Paterson 1985). This species is often found sympatric with A. chiajei   . Both species live buried in fine muddy sand but, unlike its congener, A. filiformis   feeds in the water current extending its arms vertically 3–4 cm above the sediment surface ( Vopel et al. 2003). In the Gulf of Cadiz A. filiformis   co-occurred with A. chiajei   in Mercator MV ( Fig. 7 View FIGURE 7 B). The highest density of A. filiformis   (72–144 ind.m - 2) occurs in the crater where only one specimen of A. chiajei   was collected; the latter reaches densities of 60 ind.m - 2 on the flank where the density of A. filiformis   drops to 68 ind.m - 2. Amphiura filiformis   has also a much wider distribution and has been recorded in two other mud volcanoes (Al Idrisi and Fíuza) and in association with carbonate chimneys and crusts at two other sites (West of Gibraltar and Pen Duick Escarpment) at depths between 230 and 556 m.
