“They are way smarter than you think,” Ms. Hillemacher said. Now, in a study published in the journal PLOS One on Wednesday, Ms. Hillemacher and her colleagues say they have found evidence that roosters can recognize themselves in mirrors. The mirror test is a common, but contested, test of self-awareness. The mirror test has since been used to assess self-recognition in many other species. But different cognitive processes are active in different situations, and there’s no reason to think that the mirror test is accurate for animals with vastly different sensory abilities and social systems than what chimps have.

Because Carbrook in Queensland boasted a membership unlike any other golf club on the planet: six resident bull sharks. A new corridor was opened and – sometime during those three temporary windows – six bull sharks glided into uncharted waters. Carbrook Golf Club Shark in the LakeMedia interest boomed, and the club embraced its toothy tenants with vigor. Their extended residence, he argued, sheds new light on just how adaptable bull sharks are. A stay of at least 17 years in low-salinity waters — more than half a bull shark’s lifespan — was unprecedented.

For nearly two decades, the Carbrook Golf Club near Brisbane, Australia, had the ultimate water hazard: a lake teeming with bull sharks. It all started in 1996 when raging floods swept six young bull sharks from a nearby river into a 51-acre lake near the golf course’s 14th hole. When the floodwaters receded, the sharks found themselves stuck, surrounded by grassy hills and curious golfers. The sharks, according to a new study, are more than just a fluke along the fairway. In research published last month in the journal Marine and Fisheries Science, Peter Gausmann, a shark scientist and lecturer at Ruhr University Bochum in Germany, said that the cartilaginous club members of Carbrook bull sharks demonstrate that bull sharks can live indefinitely in low-salinity aquatic environments.
