[1] It is a regular, five-armed sea star, with a large and flattened central disc (as most species in this family).

The body is covered by short and stout spines, and characterized by big, fly-trap like pedicellariae.

When alive, the central disc is swollen, forming five radial bumps.

[2][4] This species remained unknown to science until 2014,[5] but since its description it was observed many times in its environment by deep-sea research missions, such as Okeanos Explorer 2015, off Hawaii.

[3] This species lives in the depths of Pacific Ocean, and has been recorded in Hawaii, New Caledonia and New Zealand,[1] between 425 and 1500 meters deep.
