13 Sharks Test Positive for Cocaine Near Brazil
Scientists have detected cocaine in multiple sharks off the coasts of Brazil, according to a new study.

Tiger shark vomits echidna, shocking Australian scientists
A tiger shark has surprised Australian scientists on an ocean research trip by regurgitating a spiky land-loving echidna in front of them. Researchers from James Cook University were tagging marine life on the northeast coast when the three-meter tiger shark they caught vomited a dead echidna—a spiny creature similar to a hedgehog. Nicolas Lubitz said […]
Human Offspring are Not the Only Species That are Expensive!
Did you know that raising a child in the United States can cost more than $30,000 a year? But, humans aren’t alone. Offspring is expensive for every species. For decades, biologists have miscalculated the energy demands of animal reproduction by underestimating the indirect costs. Recent research led by Samuel Ginther of Monash University’s School of […]
‘I’m happy we’re not killing them any more’: Ireland’s last basking shark hunter on the return of the giants
The ambush was simple. A spotter on a hill would scan the sea and when he saw the big black fins approach, he would shout down to the boatmen. They would ready their nets and quickly row out to the kill zone. When a shark got tangled in the mesh, Brian McNeill would wait a […]
Tagging project sheds light on the elusive white shark
Researchers have discovered new white shark behaviors by attaching smart tags and cameras to their fins, revealing never-before-seen details of the lives of the elusive creatures. While the team’s previous research uncovered white sharks hunting for seals in kelp forests, the latest research revealed that the white shark adapts its behavior to suit the specific […]
