Central North Atlantic Nursery Used By Young Blue Sharks

PLOS Blue sharks may use the central North Atlantic as a nursery prior to males and females moving through the ocean basin in distinctly different patterns, according to a study published August 13, 2014 in the open-access journal PLOS ONE by Frederic Vandeperre from University of the Azores, Portugal, and colleagues. Shark populations typically organize by location and separate by sex and size, but these patterns remain poorly understood, particularly for exploited oceanic species...

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...

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. "Sharks are declining globally, yet the movements and...

The blue shark, Prionace glauca is a carcharhinid shark which is found in the deep waters of the world's temperate and tropical oceans. They prefer cooler waters and are not found, for example, in the Gulf of Mexico, the Adriatic or Red Sea. Blue sharks are known to migrate long distances, from New England to South America for example. Although generally lethargic, they are capable of moving very quickly if the need arises. Blue sharks are viviparous and are noted for their large litters of...
