Etymology: Brachiopsilus: Name from Latin 'brachium' (arm) and Greek 'psilos' (bare or smooth), referring to the smooth surfaces of their body and arm-like pectoral fins.; ziebelli: Named in honour of Alan Ziebell, a professional diver, who hand collected some of the first
specimens near the Actaeon Islands (D’Entrecasteaux Channel) when fishing for abalone. These specimens were initially displayed in a marine aquarium at his home a. More on authors: Last & Gledhill.
