Cookiecutter Shark
Luckily the cookiecutter typically resides offshore and rarely encounters people. Despite the small size, this fierce shark is notorious for its clean, deep bites. Several attacks have been recorded. Reports from shipwreck survivors have described their small but deep bites from nighttime. At least they lived to tell the tale!
Port Jackson Shark
This nocturnal bullhead shark dwells off of southern Australia, including right off of Port Jackson, hence its name. Back in 2011, there was a shark attack reported near Melbourne from a Port Jackson shark. Luckily, the man swam away even though the shark was still attached to his calf.
