Linckia guildingi, also called the common comet star, Guilding's sea star or the green Linckia, is a species of sea star found in the shallow waters of the tropical Pacific Ocean, Indian Ocean, Atlantic Ocean and the Caribbean Sea.^[1]. ^[2]

Taxonomy

Recent studies have indicated that Linckia guildingi may represent several cryptic species. Examination of the mtDNA showed that there are two clades within L. guildingi. The divergence between these implies that they separated over a million years ago.^[3]

Description

L. guildingi has a small disc and usually 5 (occasionally 4 or 6) long cylindrical arms. The upper surface appears smooth but is in fact rough to the touch with low, firm nodules. Though this starfish is often green, it comes in a range of colours including various shades of brown, blue and dull red.^[4]
