Araeosoma is a genus of deep-sea sea urchins in the family Echinothuriidae.
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. [2]
The World Echinoidea Database recognises these species: [1]
Coelopleurus is an extant genus of echinoids with fossil records dating back to the Eocene, with remains found in Europe and North America.
The Echinothurioida are an order of sea urchins in the class Echinoidea. Echinothurioids are distinguished from other sea urchins by the combination of a flexible test and hollow spines. The membrane around the mouth contains only simple plates, in contrast to the more complex mouth parts of their close relatives, the Diadematoida. They are nearly all deepsea dwellers.
Aphanopora echinobrissoides is a species of sea urchin of the family Neolampadidae. Their armour is covered with spines. It is placed in the genus Aphanopora and lives in the sea. Aphanopora echinobrissoides was first scientifically described in 1903 by de Meijere.
Araeosoma alternatum is a species of sea urchin of the family Echinothuriidae. Their armour is covered with spines. It is placed in the genus Araeosoma and lives in the sea. Araeosoma alternatum was first scientifically described in 1934 by Ole Theodor Jensen Mortensen, a Danish zoologist.
Araeosoma belli is a species of sea urchin of the family Echinothuriidae. Their armour is covered with spines.

Chaetodiadema is a genus of sea urchins of the Family Diadematidae. Their armour is covered with spines.
The Echinothuriidae are a family of sea urchins in the order Echinothurioida. Due to their soft skeletons, most are called "leather urchins", but species in the genus Asthenosoma are also known as "fire urchins" due to their bright colors and painful, venomous sting.
