Going to the beach in Australia can be a potentially deadly affair. Stonefish, pufferfish, box jellyfish, stingrays — and cute octopuses that delight oblivious tourists (and contain enough neurotoxin to kill 26 adults).
But there’s one thing you can worry less about at Australian beaches: sharks.
Researchers at Australia’s Southern Cross University (SCU) National Marine Science Centre, alongside the New South Wales Department of Primary Industries, have used two years’ worth of drone footage to study the prevalence of sharks at Australian beaches. They found that, despite attention-grabbing headlines about shark attacks (and the ensuing fear among some members of the public), shark sightings at beaches are actually rarer than we think.
“Our extensive data suggests it is up to 135 times more likely to be a dolphin than a shark,” said Professor Brendan Kelaher, who led the SCU study.
Over a total of 216 drone flights, the team identified 4388 individual large marine animals, according to the research published in the scientific journal Marine and Freshwater Research. In that sample size, the team found a huge variety of marine life, but also discovered their findings didn’t necessarily match public perception.
“Over the last three years, we have routinely captured footage of fevers of rays exceeding 100 animals, whales feeding on bait balls in the shallows and incredible chases between sharks, rays and dolphins,” said Kelaher.
“We do see potentially dangerous sharks in the shallows, but our data show they are much less common than people would have you believe.”
The video compiled by SCU is a sight to behold — particularly the “fever” of rays (add that to your collective noun list) huddled together in the clear waters as a defence against predation.
But ultimately, if the sight of sharks has you alarmed (not to mention all the species we listed in the top of this article that you may have never known about) Kelaher has some helpful advice.
“If you are concerned, it’s best to get out of the water,” he said.
