Description Diadema-sp and D. savignyi share Y-shaped blue lines of iridophores along the interambulacrals, but individuals of Diadema-sp typically exhibited a conspicuous white streak at the fork of the Y-shaped blue iridophore lines, while this feature is absent in D. savignyi. Also, the central axis of the Y-shaped blue lines of iridophores are approximately twice as long as the V-component in D. savignyi whereas it was of similar length in Diadema-sp. Two parallel lines were observed to constitute the central axis of the Y-shaped blue lines in both species, but these are considerably narrower in Diadema-sp. [details]
