Opheodesoma spectabilis is a synaptid sea cucumber in the Indo-Pacific that can be locally very abundant.

[1][2] With their flexible, wormlike bodies and mouth surrounded by tentacles[3] Opheodesoma spectabilis varies in color.

[5] As sea cucumbers most commonly do, the Opheodesoma are invertebrates that start their life cycle as Planktotrophic larvae.

[6] Opheodesoma spectabilis is located in subtropical and tropical areas such as New Caledonia, Hawaii, the Indo-Pacific,[7] East Africa, and Guam.

[8] Generally found at the bottom of the ocean floor within the sand, crumble, shells,[5] and brown algae called Sargassum.
