Habitat: This species lives buried in muddy sand and extends its arms across the surface of the substratum, feeding on deposited material.

Distribution: Reported from all round the British Isles mostly below 10 metres but there is some doubt over records from the south.

Similar Species: Other Amphiura species are similar. Mixed populations of this species and Amphiura filiformis are common.
