		The sevengill sharks (the Broadnose sevengill, Notorynchus cepedianus and the Sharpnose sevengill, Heptranchias perlo) are distinctive and rare sharks that have seven gills (most sharks have five).
		The broadnose sevengill grows to be up to 10 ft (3 m) long, is speckled and silvery; this shark has small eyes, and a wide head.
		This part of the shark's digestive tract enables the shark to efficiently digest its food in a small area, since the surface area of the intestines (where nutrient absorption takes place) is very large within the spiral.

	Case studies of the management of elasmobranch fisheries
		The single stock hypothesis for school shark is supported by evidence from scientific sampling that pupping areas of school shark tend to be in the eastern region of southern Australia and that pregnant school sharks tend to aggregate in the Great Australia Bight before August along with documented long-distance tag movements.
		Because sharks are landed headed and gutted, during 1975–77 the lengths were revised to partial lengths (fifth gill-slit to base of caudal fin) of 40cm (equivalent to 71cm total length) for school shark and 45cm (equivalent to 75cm total length) for gummy shark.
		During 1993 the landing of shark was limited to five carcasses during November in the area west of the South Australia-Victoria border and during December in the area east of this border.

		In Australia, the target species in some shark fisheries are adequately managed but there has been little management of non-target shark species and there is little information on the biology of their local populations.
		Among this group of non-target species, the broadnose sevengill shark and the piked spurdog are of special interest.
		Therefore, the main purpose of this research is to gain knowledge of the basic biology of these two species and to provide essential data for their management, sustainable use and conservation.

		Unfortunately, the shark skeleton is cartilaginous and rarely fossilized, so previous studies were limited in scope.
		The first phase of this project is focused on sharks because these are widely regarded as primitive gnathostomes (jawed vertebrates) and have often been compared with extinct forms such as placoderms (Paleozoic armored fishes) and acanthodians.
		Current projects include the braincase of the modern broadnose sevengill shark Notorynchus and studies of several extinct chondrichthyan braincases including Pucapampella (Lower Devonian of Bolivia and South Africa), Cladodoides wildungensis (Upper Devonian of Germany), Tamiobatis (Upper Devonian and Mississippian of North America), Cobelodus (Pennsylvanian of North America), and Cretaceous hybodont sharks.

	IUCN Red List of Threatened Species: Notorynchus cepedianus
		Although wide-ranging and moderately common (where not heavily exploited), this shark is restricted to a limited inshore depth range in heavily fished temperate waters and is exposed to intensive inshore fisheries over most of its range.
		The central California stock in the San Francisco Bay area is thought to have been depleted in the early 1980s, but lack of fisheries data elsewhere make it impossible to determine whether this pattern of depletion occurs throughout its range.
		A powerful predator with indiscriminate feeding habits, this shark is generally regarded as potentially dangerous to humans in open waters, particularly when provoked.
