The Grey Nurse Shark (Carcharias Taurus) is large and fearsome looking but is actually a fish-eater. During certain seasons it occurs in schools (nurseries), in gutters and on coastal reefs. It has a conical snout and two large dorsal fins that are about equal in size. The first dorsal fin is closer to the pelvic than pectoral fins. The teeth are long, slender and slightly curved with a single pair of basal cusps (appearing as ‘snaggle-toothed’). These teeth are perfectly shaped for feeding on schooling fish and are not adapted for attacking and ripping large animals (including humans). They grow to around 3.2 metres.
During the 1950’s and 60’s they were considered responsible for attacks on Humans and were subsequently culled. They are now protected throughout Queensland waters although their recovery will be slow given the severe initial culling and their low breeding rate (fecundity), and they are still high on the list of threatened and endangered marine species.
