Ecology of Amphiura filiformis

Main Ref.	Garmendia, J.M., J.M. Parada and J. Mora, 2003
Remarks	Commonly found at depth >30 m, in fine sand sediments (Ref. 96521). Free-living (Ref. 3123). A mobile suspension feeder (Refs. 95752, 96501). When feeding, its disc is buried 4 to 8 cm below the sediment surface, while its two arms are extended into the column (Ref. 113568).
