Bull sharks spend longer in Sydney waters due to warming seas
Sydney’s Taurus shark season expanded due to ocean waters in a trend that could bring to a permanent proximity with swimmers and surfers from the largest city of Australia, one of the most dangerous sharks in the world.
The new analysis has proven that sharks delayed their migration to the north, and now compared to 2009, it is now spending 15 days more in Sydney port and its environs every year.

Sharks abandoned Sydney in April or May to spend their winters in the warmer seas of Queensland, to work Dr. James Cook University. Nicolas Lubitz. They’re coming back in November.
“When temperatures begin to fall slightly below 20 degrees, a clue for the bullies to start migrating to North NSW and Queensland, and sometimes to Cape York,” Lubitz said.
“Our analysis shows that these temperatures are now less occurred during their time in Taurus Sharks Sydney. Basically, they cannot get that clue.”
In the analysis, the average ocean temperatures in Sydney in the last 40 years have increased by 0.67 degrees.
Lubitz said that shepherd bull sharks were more south in the south and were more than enough to solve the migration regimes.
“A central climate change on the southern coast of NSW has been considered a warm point. It has one of the fastest heating rates from any sea region in the world.”
