Afrivoluta pringlei (Tomlin, 1947) Emblem of the Conchological Society of Southern Africa


Class: Gastropoda

Order: Neogastropoda

Family: Marginellidae


First described in 1947 by J.R le Brockton Tomlin, this unique shell was probably the first shell to be described from material taken by a South African Trawler. Tomlin referred the first specimens, discovered by Dr. John A Pringle, past director of the Natal Museum, to the family Volutidae. Subsequent study of the anatomy has shown it to be a primitive Marginellid, the biggest species from Southern African waters.


The shells are found in deep water (140-500m) from the Agulhas Bank and its slopes, from off Port Alfred to Jeffreys Bay.


The Marginellidae is a large family of tropical and subtropical gastropods. Most species burrow shallowly in sand or gravel. They are active predators, (although carrion is also eaten), feeding mainly on small gastropods and bivalves. A poison gland, opening into the buccal cavity, is evidently used to immobilize the prey, but, curiously, many species lack a radula. Interesting enough, Afrivoluta pringlei has a very broad comb-like radula.
