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.
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.
