The great white shark is one of the most commonly found in the waters of New Zealand. [216] As of April 2007, great white sharks were fully protected within 370 km (230 mi) of New Zealand and additionally from fishing by New Zealand-flagged boats outside this range. The maximum penalty is a $250,000 fine and up to six months in prison. [217]
The Lamnidae are the family of mackerel sharks known as white sharks. [2] They are large, fast-swimming predatory fish found in oceans worldwide, though they prefer environments with colder water.

Otodus chubutensis was a large lamniform shark, with the largest individuals reaching a body length of 13.5 metres (44 ft). [10] Relatively large individuals reached body lengths of 9–11 metres (30–36 ft). [11] Smaller individuals were still about the size of the modern great white shark, reaching body lengths of 4.6–6.3 metres (15–21 ft).
Great whites possess large, dagger-like teeth; basking shark teeth are much smaller 5–6 mm (0.20–0.24 in) and hooked; only the first three or four rows of the upper jaw and six or seven rows of the lower jaw function. In behaviour, the great white is an active predator of large animals, not a filter feeder.
