Crambionella

Crambionella is a genus of Cnidarians belonging to the family Catostylidae. The genus is distinguishable from other Castostylid species by a terminal club on each oral arm without filaments and a canal system featuring a narrow, wide-meshed intra-circular network of interconnected vessels. These vessels solely communicate with the ring canal and not with the radial canals. Four species belong to the genus Crambionella (Stiasny, 1921): C. annandalei (Rao, 1931), C. helmbiru (Nishikawa, Mulyadi & Ohtsuka, 2014), C. orsini (Vanhöffen, 1888) and C. stuhlmanni (Chun, 1896). C. orsini is the type species for the genus.

Species of Crambionella can be found throughout the Indian Ocean ranging from South Africa to Java. All 4 species can be found during the summer and winter in their respective habitats. Many nations bordering the Indian Ocean harvest Crambionella species for food, with Japan, the Philippines, Vietnam, Malaysia, Thailand, Indonesia, Singapore, and Myanmar being significant consumers.
