A strange arrangement of ichthyosaurus bones suggests that a giant (and hypothetical) Triassic-era sea monster might have enjoyed playing with its food, artfully rearranging the bones of the sharks it ate, according to a Boston-based paleontologist. Perhaps it was making a self-portrait. Or maybe it was lonely and wanted to create an imaginary kraken pal.
Sea creatures like octopus, squid and cuttlefish are among nature’s best camouflage artists, changing color to blend into their environments. This is partly because cephalopod skins have some primitive optical abilities — their skin has the same light-sensing proteins found in eyes — that allow them to “see” through their skin. And the Department of Defense would like to know their secrets.
We're not endorsing any big bets, of course, but a pair of London mathematicians say they're confident Spain will win the World Cup final Sunday. It's not just a prediction -- it's science.
Queen Mary, University of London professors -- and soccer fans -- Javier López Peña and Hugo Touchette collected ball-passing data from each World Cup team and used graph theory to analyze each team's style of play. Their results reveal "gaping holes" in England's strategy against Germany, which they say explains team England's loss. The results also show that Spain's propensity for passing might help them beat the Dutch this weekend.
An underwater photographer was peacefully cruising along a reef when this speedy octopus snaked out an arm and grabbed his Lumix away. The cephalopod then proceeded to jet away at top speed, while filming the whole thing -- unfortunately, with more than a couple of its thumbs covering the lens.
Marine biologists discover octopuses that engage in unexpectedly complex mating rituals
By Gregory MonePosted 04.03.2008 at 9:42 am 1 Comment
UC Berkeley scientists have found a species of octopus whose members flirt, hold "hands", and ward off rival suitors as part of a complex mating ritual. Previously, researchers thought octopuses were fairly boring on the dating front, and didn't engage in complex behavior (which would be kind of a bummer, given that both male and female die not too long after mating). But the new work, published in Marine Biology, reveals that these slinky creatures have got their own moves.
Roger Hanlon's cephalopod research hits the mainstream in a popular YouTube video

You likely don't know Roger Hanlon by name, but you may very well have been forwarded the video clip above in the past year--which means you know his research. Dr. Hanlon studies cephalopod camouflage. In addition to controlled experiments in his lab, he has been on thousands of dives following cuttlefish, squid and octopuses through their natural habitats. Using underwater digital video cameras, he and his team are able to capture the intricate physical patterns these animals display across their bodies when they want to go unseen.
