About this species

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.
