Eponymy: Ryan Daly is a South African zoologist and oceanographer who is Research Director (2017– present) at ‘Save Our Oceans’ D’Arros Research Centre. [...] (Ref. 128868), visit book page.

Ραχιαίες άκανθες (συνολικά) : 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 8; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 7. This species is distinguished by the following characters: cephalic sensory-canal pore system lacking only an IT pore (Pattern 2); dorsal/anal fin-ray formula 8/7; pointed pectoral-fin when depressed, branched rays 15; fifth pelvic-fin ray is present and about 20% of fourth; absence of dark markings on head; long, white anterior narial tubes; bright red-and-white markings on head and orange and yellow bars crossing the translucent body (Ref. 120586).
