Tetractenos glaber (Smooth Toadfish)

From Fishes of Australia: Differs from the Common Toadfish (Tetractenos hamiltoni) 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.

Note also the yellow-red colouration of tail (not seen in T. hamiltoni)
