Like other known megatooth sharks, the fossils of O. angustidens indicate that it was considerably larger than the extant great white shark, with the largest individuals possibly measuring up to 11–12 metres (36–39 ft) long. [7] [8] A well preserved specimen from New Zealand is estimated at 9.3 m (31 ft) in length. [5]
Great white sharks can swim at speeds of 25 km/h (16 mph) [9] for short bursts and to depths of 1,200 m (3,900 ft). [10] The great white shark is arguably the world's largest-known extant macropredatory fish, and is one of the primary predators of marine mammals, such as pinnipeds and dolphins.
As of 2022, more than 426 miles (686 km) of passageways had been surveyed, [4] [5] over 1.5 times longer than the second-longest cave system, Mexico's Sac Actun underwater cave.

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. The name of the family is formed from the Greek word lamna , which means "fish of prey", and was derived from the Greek legendary creature , the Lamia .
The reality is that humans are a bigger threat to sharks than they are to us. Sharks are apex predators that keep biodiversity balanced by maintaining the species below them in the food chain.
