They can reach 1.2 meters in length, and their snouts and muzzles are covered with pores that allow them to search for prey by sensing movement and electricity. Ghost sharks possess three dental plates, those in the lower jaw are good at crushing and those in the upper jaw are sharp and jagged. This shark lives mainly in Australian and New Zealand waters.
