Standard Common Name
Red Eel Goby
The Red Eel Goby is a very elongate species with long based dorsal and anal fins. It has a large oblique mouth and rudimentary eyes.
The live colouration of this species is vivid pink. Saville-Kent’s (1889) original description of the species stated that the fish was rosy pink in life with a carmine longitudinal stripe and smaller carmine streaks branching from the longitudinal stripe that delineated the outlines of the myotomes. Its fins were yellowish.
Fish in the genus Caragobius can be separated from other gobies by several osteological characters. Other useful features that can be used to distinguish Caragobius are the rounded pectoral and pelvic fins, the dorsoventral symmetry, rudimentary eyes, slightly depressed head, and lack of opercular pouches and fang-like teeth.
The Red Eel Goby grows to at least 10 cm in length.
There are two species in the genus Caragobius. The second is C. urolepis, which is not known from Australian waters. It occurs in India, Thailand, Indonesia, the Philippines, Taiwan, Japan and Fiji.
The species is endemic to Australia, occurring from north-western Western Australia to the Gulf of Carpentaria, Queensland.
