|Researched by:||Jacqueline Hill and Emily Wilson||Refereed by:||Dr Mattias Sköld|

|Class||Stelleroidea||Starfish, sea stars, cushion stars and brittlestars|
|Recorded distribution in Britain and Ireland||Most British and Irish coasts although records have not been found for the south east of England.|
|Habitat information||Lives buried in the surface of fine muddy sands, mostly at depths greater than 15 m although can be found at extreme low water.|
|Description||A small brittle star, disc up to 10 mm in diameter, with very long arms (10x disc diameter) which lives buried in muddy sand. The dorsal side of the disc is covered with fine scales but the ventral side is naked. It is red-grey in colour. Amphiura filiformis extends its arms vertically 3-4cm into the water current to feed, in contrast with the deposit feeding Amphiura chiajei with which it is often found.|
