13,800-year-old Haida site found underwater off British Columbia

A new archaeological study has discovered a Haida site dating back 13,800 years off British Columbia’s Juan Perez Sound. Led by archaeologist Quentin Mackie of the University of Victoria, the team discovered the site near the Haida Gwaii Archipelago and is believed to feature a fishing weir, a man-made channel used to corral fish.

Great Barrier Reef potato cod at risk from own friendliness

Potato cod in Queensland are at risk and their placid and curious nature appears to be playing a major part. The Great Barrier Reef Marine Park Authority (GBRMPA) is investigating reports that illegal fishing and fish 'framing' are responsible for declining potato cod numbers at the Cod Hole, a popular dive site off Lizard Island.

New research reveals life history of salmon sharks

As the saying goes, you are what you eat. Researchers at Stanford University's Hopkins Marine Station are using this adage to better understand the life history of the salmon shark. An important apex predator and cousin of the great white, this far-ranging species roams the entire North Pacific Ocean, from Alaska to the warm sub-tropics of Hawaii and the Baja Peninsula

Humpbacks make 'tick-tock' sounds to flush out hiding fish

Scientists have known that humpback whales have a trick or two when it comes to finding prey at the bottom of the ocean, but how they locate a meal at night with little or no light has remained a mystery.

A new study has analyzed the importance of specific auditory cues that the creatures emit as they search the deep ocean for prey. 'Humpback whales are known to cooperate with others to corral prey near the surface,' said Professor Susan Parks of Syracuse University. “Recent studies suggest they may cooperate [with each other], when feeding on bottom prey, as well”, she added.
