Araeosoma is a genus of deep-sea sea urchins in the family Echinothuriidae.

Description and characteristics

Species in this genus are distinguished from other Echinothuriidae by their lack of ophicephalous pedicellariae (despite presence of dactylous ones), and the presence of prominent membranous gaps along horizontal sutures in interambulacral zones of both oral and aboral surfaces.
