Astrosarkus idipi is a species of sea star in the family Oreasteridae. It is the sole species in the genus Astrosarkus.[1] It is sometimes referred to as a "Pumpkin sea star".
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 in diameter for 10 cm 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.[2]
Habitat and repartition
This sea star lives in the sub-reef zone, between 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.[2]
In popular culture
Along with some other deep-sea creatures, this sea star has been used in Japan as a model for a sushi-shaped gachapon toy.[3] There, the species is referred as ryugu sakura hitode, which means "dragon palace cherry blossom sea star".[3]
