Iconaster longimanus, the icon star or double star, is a species of starfish in the family Goniasteridae. It is found in the west and central Indo-Pacific Ocean. The genus name comes from the Greek eikon, meaning portrait or image and possibly referring to the way the marginal plates frame the disc, and aster, meaning star. The specific name comes from the Latin longus manus and refers to the long, slender arms.[2]
Iconaster longimanus has five thin, tapering, flattened arms. It grows to a diameter of about 30 centimetres (12 in) with a central disc about 10 cm (4 in) across. It has a marginal row of large plates that resemble mosaic tiles and contrast in colour with the disc. The margin is usually tan with symmetrically arranged dark brown bands and the disc is orange-brown.[3][4]
