It is thought that this these Cyclops Sharks don't live very long in the wild and that is why they are almost never seen.
Adult Dusky Sharks can grow to 4.2 m (14 ft) in length and weight in at 347 kg (765 lbs). They are often caught by fisherman and used it shark fin soup and also for their skin and liver oil. Unfortunately their slow reproductive rate makes them very susceptible to overfishing.
