Demospongiae sponge with commensal entoprocta/kamptozoa
Smoking like a volcano on an alien planet, and triggered in some mysterious way by the full moon, a sponge spawns deep on a reef in Indonesia’s Banda Sea. Entoprocts cluster thickly around the vent, combing the sponge’s exhalations of water for microscopic particles of food.
