Amphiura est un genre d'ophiures (animaux marins ressemblant à des étoiles de mer souples) de la famille des Amphiuridae.
Description et caractéristiques








Ce sont des ophiures grêles, au disque central réduit mais aux bras très allongés. Elles vivent enterrées dans le sédiment, d'où elles ne laissent dépasser que leurs bras couverts d'épines articulées, qui leur servent à capturer le plancton dont elles se nourrissent. On en trouve dans toutes les mers ouvertes du monde (sauf la mer Noire), des pôles aux tropiques et des plages aux abysses.
