Alex Mustard describes the motivation and technique behind his image of a spider crab aggregation. (via DivePhotoGuide.)

“Some photographs happen by chance, others after months of planning. This spider crab image has had a long gestation, which I guess makes it all the more satisfying now it is sitting on my hard drive.”

Monterey Bay Aquarium’s white shark summer Photo

Monterey Bay Aquarium’s white shark summer

Monterey Bay Aquarium’s Sea Notes reports that this summer, as well as tagging great whites accidentally caught in commercial fisheries, the aquarium will use a different technology to try to prove if sharks seen and caught on both sides of the border are in fact part of the same population. They plan to use special acoustic tags, as used in tracking salmon, that each have a unique signal that is recorded by a receiving station as tagged animals pass it. Six sharks are to be fitted with these tags this summer.

The recent confirmation, achieved by DNA sampling, that the Californian great white has a unique genetic identity different to other great whites reinforces how crucial it is to understand these apex predator’s behavior and movements.

Scientific American on today’s sharks

Scientific American has published an article titled: Today’s Sharks: Smart, Tagged and in short supply. It highlights the race that scientists face with studying the shark before it is fished out of existence. The article also contrasts the high-tech research methods currently employed, including satellite tracking, genetic analysis and HD cameras, with the available technology in 1987 when Discovery first launched their Shark Week series. Amongst the results is a growing realization that sharks are very intelligent:

“Many sharks have good learning capacity, which is one way we measure intelligence,” says Samuel Gruber, a marine biologist at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS), who discovered in 1975 that lemon sharks could learn a classical conditioning task 80 times faster than a cat or rabbit. “I was shocked to find that they could learn so rapidly,” he says. Gruber’s National Science Foundation–supported Bimini Biological Field Station in the Bahamas, known as Sharklab, is now planning to start a doctoral research program on shark cognition.
