Elasmobranchii (sharks and rays) > Hexanchiformes (Frill and cow sharks) > Chlamydoselachidae (Frilled sharks)
Etymology: Chlamydoselachus:Greek, chlamys, -idos = cloak, cape + Greek, selachos = shark (Ref. 45335); africana:Named africana is in allusion to the Marine and Coastal Management research
vessel “Africana” in recognition of the excellent research surveys this vessel has conducted over the past several decades. It is also the vessel that collected.
