Scientists discover new hammerhead shark species — and it’s already at risk
A new-to-science hammerhead species, the shovelhead shark, has been hiding in plain sight for three centuries due to its close resemblance to a long-lost relative, the bonnethead shark.

Tiger Sharks Off the Coast of Brazil Found Ingesting Rare Earth Elements from Modern Technology
Recent research has revealed that tiger sharks off the southern coast of Brazil are ingesting contaminants commonly found in modern technology, including rare earth elements (REEs) used in cellphones and electric cars. These metals, crucial for various high-tech devices, have been detected in alarming amounts within the tissues of these apex predators. Scientists, led by […]
Watch what looks like a Jaws remake as 14-foot great white shark follows kayakers

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.
