Short Description
A large seven-gilled cowshark [536] with a wide head, short and blunt snout, and fusiform body. Dorsal fin small, origin may vary from over insertion of pelvic fins to over free rear tips of pelvic fins. Anal fin smaller than dorsal fin. Tooth count 15-16/13. Reddish-brown to silvery-grey or olive-brown with numerous small black spots on body and fins; cream below [536].
Diet: southeast Tasmania (data base 178 specimens): Teleosts were the main prey at the Derwent Estuary, occurring in 49.0% of stomachs analysed, followed by batoids (30.6%) and sharks (28.6%), while mammals (mainly seals) occurred in 12.2% of stomachs (Table 2). At a species level, southern shortfin eel Anguilla australis occurred most frequently (14.3%), followed by white-spotted spurdog Squalus acanthias (12.2%), Australian sardine Sardinops neo pilchardus (12.2%) and gummy shark Mustelus antarcticus (10.2%). Australian fur seal Arctocephalus pusillus doriferus (8.2%), southern eagle ray Myliobatis australis, banded stingaree Urolophus cruciatus and elephantfish Callorhinchus milii were also important (8.2% occurrence in each case). In Norfolk Bay, sharks were the most important prey (38.6%), followed by batoids and teleosts (27.6% in both cases), and mammals occurred in 23.6% the stomachs containing food (Table 2). At a species level, gummy shark was the most important prey (25.2% occurrence), followed by Australian fur seal (14.2%), Melbourne skate Spiniraja whitleyi (10.2%), spurdog (8.7%) and southern eagle ray (7.9%) [14363]
