Blue Spotted Sea Urchin Astropyga radiata occurs in the subtropical tropical Indo-Pacific Ocean from the African coast to Australia and to Hawaii in a depth range from 0 to 60m, usually 10 to 30m, max. test diameter 20cm. \n\nThe species is often found in lagoons and bays where the substrate is sand, shingle or coral rubble. Sometimes many urchins collect together in one locality in dense aggregations. This specimen is transported by an Urchin Crab. \n\nUrchin Crab or Carrier Crab Dorippe frascone occurs in the Indian Ocean along the coasts of East Africa, in the Red and the Arabian Sea, and the Indian subcontinent an in the Western Pacific Ocean in the Philippines, in Indonesia and in northern Australia. The species occurs also in coastal areas of Japan, China and Korea in a depth range from 1 to 100m, max. size of the carapace 5cm. \n\nLembeh Strait, Indonesia\n1°27'13.104 N 125°14'14.634 E at 12m depth

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
