Onespot Fringehead

Long, eel-like body with an enormous mouth used aggressively in territorial displays — two males will "jaw wrestle" with mouths wide open. A single ocellus (eyespot) behind the first dorsal fin is the key field mark. Brown with orange and blue markings in the mouth interior. Adults reach 9–12 inches.\n\n

Not a targeted species. More often observed by divers than caught by anglers. Famous for extraordinary territorial aggression despite its small size.
