Etymology: Akheilos: Named for the Greek mythological sea daemon Akheilos, who was a handsome boy until turned into a shark by the goddess Aphrodite as punishment for boasting that he was more beautiful than she (no deep meaning or special relevance to the shark, simply a “cool name” that “just seemed to click”; William T. White, pers. comm.). (See ETYFish); suwartanai: In honor of Atjep Suwartana, first director of the Research and Development Center of Oceanology, Indonesian Institute of Sciences in Ambon (where the second author works). (See ETYFish).

Colouration: pale brown with numerous rusty brown spots, small brown spots forming two indistinct saddles on dorsal surface of predorsal body, broken ocellus-like marking on side behind pectoral fins and under each dorsal fin (Ref. 120897).
Depth of occurrence unknown. Stomach contained several anterior sections of a small snake eel (Ophichthidae) (Ref. 120897).
