Pincushion Sea Star Culcita novaeguineae is a sea star from the Class Asteroidea, of phylum Echinodermata. The very short arms morph very gradually into the central disc. \nThe species is found in coral reefs all over the tropical Indo-Pacific feeding live coral. It is a bottom dweller feeding on sessile prey as its a slow mover, even slow for an Asteroid, due to its very short arms. While Culcita novaeguineae is not as infamous as the crown-of-thorns starfish (Acanthaster planci), it can have similar effects on coral reef ecosystems if its numbers are not kept in check. \n\nCommensal Shrimps Periclimenes and Zenopontonia sp. often have a similar color to the host. \nSeveral species are found in association with a starfish, usually on the undersurface. The shrimps feed on mucus secreted by the starfish and benefit from the protection from predation provided by its carnivorous host. \n\nLembeh Strait, Indonesia\n1°27'38.166 N 125°13'34.284 E at 18m depth
