Animal Species:Common Toadfish, Tetractenos hamiltoni (Gray & Richardson, 1843)
The Common Toadfish is found in shallow coastal waters and estuaries along the eastern Australian coastline. Like most toadfishes, the species is very toxic and should not be eaten.
The Common Toadfish is a sandy to whitish colour. It has small brown spots over most of the back and upper sides. The lower sides often have brown bars and blotches.
The species has small gill slits located just in front of the pectoral fin bases and a distinct skin fold running along the lower sides. Its teeth are fused and form a beak-like structure with a median groove. The family name Tetraodontidae means "four teeth".
The species looks similar to the Smooth Toadfish. They can be separated by skin texture and colouration. The Smooth Toadfish has larger spots and blotches. It has minute spines embedded in the skin which give it a smooth texture, hence the common name. The Common Toadfish is covered with small prickles.
It grows to 13 cm in length.
The Common Toadfish is found in shallow coastal waters and estuaries along the eastern Australian coastline from northern Queensland to southern New South Wales.
