Summary:
A pale grey to olive-green speckled pufferfish becoming white below, with a dark stripe along the side from above the pectoral-fin base to the caudal-fin base, that continues on the head below the eye onto the prominent chin (stripe sometimes very faint or indistinct on the head), and no vertical lines or stripes on the cheek.

Scalytail Toadfish, Torquigener squamicauda (Ogilby 1910)

More Info


Distribution

Endemic to eastern Australia from about Bowen, Queensland, to south of Jervis Bay, New South Wales. Usually inhabits sandy areas in clear sheltered bays, estuaries and coastal waters, in depths to about 10 m. Individuals often lie partly buried in sand, and sometimes aggregate in large numbers.

Features

Dorsal fin 9-10; Anal fin 7-8; Pectoral fin 13-17; Caudal fin 11; Vertebrae 7 + 11,8 + 10,8 + 11. 
Upper and lower lateral lines associated with strongly developed double rows of flattened spine-enveloping papillae, extending from posterior margin of main spinous covering to caudal fin base; dense array of spines on the back and cheek, and overlapping the whole length of the prebranchial margin.

Colour

Pale grey to olive-green, with many small, irregularly scattered greenish to brown flecks, giving a very speckled appearance; greenish-brown tinge continued on cheeks, grading to white ventrally; sometimes faintly discernable darker bands cross the top of the head between eyes and dorsal fin, and through the dorsal-fin base; dark stripe along sides from above pectoral fin insert to middle of caudal fin base; yellowish to silvery-grey along sides between lateral stripe and ventrolateral skin fold; band of small greyish specks around chin; belly white; pectoral, dorsal and anal fins pale, caudal fin with a yellowish-brown tinge along middle rays.

Fisheries

Occasionally taken as by-catch in prawn trawl fisheries.

Similar Species

Differs from the Yelloweye Toadfish, Torquigener parcupsinus, which also possesses well-developed papillae associated with the upper lateral line on the caudal peduncle, in having much more densely arranged spines on the back that project from wider papillae, and a dense overlay of spines on the prebranchial margin. T. parcuspinus also lacks a dark stripe along the side.
Although similar to the Weeping Toadfish, Torquigener pleurogramma, the Scalytail Toadfish lacks vertical ("tear-like") lines on the cheek.
