Summary:
A sandy to whitish pufferfish with small brown spots over most of the back and upper sides, and brown bars and blotches usually on lower sides. Inhabits shallow estuaries, and often lies buried in sand with only the eyes exposed.
Pufferfishes (toadfish) are very poisonous and this species should not be eaten - or fed to pets.

Common Toadfish, Tetractenos hamiltoni (Gray & Richardson 1843)

More Info


Distribution

Recorded in Australia from northern Queensland to Flinders Island, Tasmania, and at Lord Howe Island; also in New Zealand. Occurs in a range of habitats including bays, sandy coastal areas, and the mouths of estuaries to less saline upstream parts of rivers.

Feeding

Carnivore - feeds on crustaceans, molluscs, polychaete worms and echinoderms.

Biology

Spawns in winter. 

Remarks

Common Toadfish possess occlusable yellow corneas - the species can vary the amount of pigment in its cornea by expanding chromatophores. The cornea becomes yellowish under bright light.

Similar Species

Differs from the Smooth Toadfish, Tetractenos glaber, in skin texture and colouration. The Smooth Toadfish has larger spots and blotches, and minute spines embedded in the skin giving it a smooth feel, hence the common name. The Common Toadfish is covered in small prickles.
