The Blue Linckia inhabits intertidal reef areas throughout the Indo- West Pacific region. It attains a large size (arm radius 180mm.), is brightly colored, and is usually found lying unconcealed on or near coral clumps in the reef flat. It can be found also on the reef crest, lying either exposed on the algal rim or partially hidden under coral boulders in the rubble zone. There is very little color variation within this species on the Great Barrier Reef. The most frequent number of arms is five although this ranges from three to seven, but the extremes are rare.
