Notes: "Touch-me-not sponge." In the Bahamas it occurs as thick encrustation to tall masses with scattered wide and deep atria, maroon to orange-brown; oscules inside atria are directed diagonally upwards. In other Caribbean areas it consists of large vases/tubes, single or in groups, while in the Bahama it appears as if these vases had laterally fused. It produces strong itching when handled.
