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 {{cvt|30|cm}} in diameter for {{cvt|10|cm|0}} 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.Christopher L.

Habitat and repartition

This sea star lives in the sub-reef zone, between {{cvt|67|and|200|m}} 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.
