Coelopleurus exquisitus
''Coelopleurus exquisitus'' (exquisite urchin)〔(''Coelopleurus exquisitus'' ) Encyclopedia of Life. Accessed 20 September 2011.〕 is a sea urchin species found off the coast of the island of New Caledonia in the Pacific Ocean. It is an epifaunal deepwater species living at depths between and was only identified and named in 2006.〔(A new species of Coelopleurus (Echinodermata: Echinoidea: Arbaciidae) from New Caledoni ). ''Zootaxa'', Magnolia Press. 7 August 2006. Accessed 20 September 2011.〕
==Colouration==
The colouration and pattern of ''Coelopleurus exquisitus'' is vibrant and distinctive. Examined individuals of the species show that the test is up to in diameter, with long, curved spines. These primary spikes are curved and banded with red and light green. It has large purple interambulacral regions with undulating lavender lines, while the remainder of the epithelium is coloured olive or light brown. This makes it highly sought-after by collectors, which may threaten the species. However, too little is known about the species to confirm their number. The purpose of the pigmentation, which is present in both the skin and skeleton, is also unknown, given the low light conditions of its habitat.〔〔 One presented theory is that the species migrated from shallower waters and has maintained its colouring.〔O'Brien, Helen. (New urchin leaves eBayers all at sea ). ''The Guardian''. 17 August 2006. Accessed 20 September 2011.〕
