Cobbler Fish: Overview
Cnidoglanis macrocephalus is a catfish species commonly known as the cobbler, estuary cobbler, or Swan River catfish. Cobblers have venomous spines on their fins that can cause painful wounds. They complete their lifecycles in marine or estuarine waters.
Cobbler Fish: Habitat and Characteristics
The South Australian cobbler, often called cobbler or soldier, is a brown coloured fish living in Australian estuaries. It grows to around 22 cm. Most venomous fish injuries occur when the fish are handled.
Cobbler Fish: Behavior and Reproduction
The estuary cobbler lives in shallow bays and sandy inlets near river mouths, over sand, rocks and weeds. By day, it stays in holes and on banks. At night it feeds on molluscs, crustaceans, worms, algae and debris. Juveniles eat more crustaceans while adults feed on molluscs and worms. Estuary cobblers fall prey to birds.
Female cobblers lay 500 to 3,500 eggs. Shallow vegetation and fallen trees provide suitable habitat. With poor eyesight, they use barbels to search for food.
Cobbler Fish: Spines and Predators
Cobbler fish have sharp dorsal and pectoral fin spines. The fins’ poison can cause inflamed lesions. The male cobbler makes a tunnel for the female to lay her eggs in. Cobbler meat is nutritious but spines must be removed before eating. Main predators include sharks, larger fish, and marine birds.
