Latest Salmon shark Stories
It's hard to study a creature when you only catch fleeting glimpses of it. Up until recently, that was one of the big stumbling blocks for marine biologists and ecologists, but advances in electronic tracking technology have allowed them to peer farther across, and deeper under, the surface of the oceans than ever before.
Satellite tracking systems and acoustic sensors are giving researchers insights into the behavior and lifestyles of some very elusive animals in the ocean, including the fabled white shark.
A great white shark named Nicole logged more than 12,000 miles swimming from Africa to Australia and back, the first proof of a link between the two continents' shark populations, researchers say. Tracking a shark from Africa to Australia is one of the most significant discoveries about white shark ecology and suggests we might have to rewrite the life history of this powerful fish.
Electronic tags broadcasting from the dorsal fins of salmon sharks reveal that these top predators migrate from the glacial waters of Alaska to the warm seas off Hawaii, according to a new study in the journal Science. The salmon shark's ability to survive such a broad range of thermal conditions is attributed to high levels of specialized proteins that keep its heart muscle cells beating at very low temperatures, say the study's authors.
