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. In the study, which was published in the journal Science of the Total Environment, researchers set out to analyze the levels of cocaine as well as benzoylecgonine, a metabolite of cocaine, in Brazilian sharpnose sharks (Rhizoprionodon lalandii). The […]
Shark Populations Plummet as Brazilians Feast on Them
In Cananéia, along Brazil’s coastline, lies a trade hidden from casual view. Amidst the colorful fishing boats and tranquil waters of the estuary, an industry thrives on the unassuming wharf.

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 […]
