"For the second year in a row, over 100 hammerheads have gathered at one of
Australia’s busiest beaches, Burleigh Beach in the Gold Coast.
Why aren’t we alarmed? Because these are small scalloped hammerheads, not the
larger great hammerhead. Even this species is feared far more than it deserves.
Plus, these scalloped hammerheads are juveniles between 40 cm and 1 metre.
Scalloped hammerheads prefer tropical and temperate oceans. But as the oceans
heat up, they’re moving further south – just as we’re seeing in Western
Australia, where these timid sharks are now gathering off Perth.
These remarkable sharks are one of the few social sharks, gathering in large
numbers as juveniles and adults. But this behaviour makes them easy to catch
and kill for their fins or meat. Their numbers have fallen by over 80% over the
last five decades. It’s urgent we find ways to protect them wherever they
school."
