Cnidoglanis macrocephalus is a speciesofcatfish (order Siluriformes) of the familyPlotosidae, and is the only species of the genusCnidoglanis.[1] It is commonly known as the cobbler, estuary cobbler, deteira, estuary catfish, South Australian catfish, or Swan River catfish.[2][3]
Like other eeltail catfish, the cobbler resembles a catfish in front, but an eel behind. It can grow up to 91.0 centimetres (35.6 in) SL, 2,500 grams (5.5 lb). They may live up to 13 years.[2] The dorsal and pectoral fins have sharp, venomous spines that can inflict painful wounds.[2]
Treatment
Treatment of injuries by submersion of the wound in hot water is suggested though the role of heat in denaturation of toxins is debated.[4]
However, despite this study, hot water immersion is still the recommended first aid treatment for envenomation.

Ecology
The estuary cobbler is an inshore marine species which lives in shallow bays and sandy inlets near river mouths. It is found most frequently over sand, rocks and weeds in clear to turbid waters. By day, the estuary cobbler are most often found in holes and on ledges in banks.[2] Estuary cobblers stay in holes and under ledges during the day, then come out at night to feed. They are opportunistic feeders, primarily feed on molluscs (bivalves and gastropods), crustaceans (prawns and amphipods), polychaete worms, algae, and organic debris. Juveniles eat more crustaceans, often from among drifting macrophytic algae, while adults feed mainly on molluscs and polychaetes.[2] They are prey to birds such as cormorants and pelicans.[2]
