Description and characteristics
It is a big sea star with a subpentagonal and very plump body. It is quite recognizable because of its bright orange color, and globally displays the color, texture and size of a pumpkin. It is thus a very big star, measuring approximately 30 cm (12 in) in diameter for 10 cm (4 in) high. The lower face is white dirtied with orange, and crossed by 5 ambulacral grooves. Inside the body, the skeleton is strikingly reduced: the main part of the mass of the star is muscular.[3]
Habitat and repartition
This sea star lives in the sub-reef zone, between 67 and 200 m (220 and 656 ft) deep, and seems rather widely distributed in the Indo-pacific, From Reunion island to Samoa. However, it is still poorly known, and only 6 specimens have been collected to this day.[3]
