Say It With Sea Otters is a blog where adorable cartoon animals deliver difficult messages. Here are some examples: 1, 2, 3, 4 and 5. While the sea otter has a well deserved reputation for extreme cuteness, these aquatic weasels engage in behavior that to humans seems truly reprehensible. Of course, we humans haven't exactly treated them well throughout history. Indeed, the first scientist to describe them, George Wilhelm Steller, emphasized their valuable fur in his description of them.
Microworlds is the blog of biology student Daniel Stoupin, and he also has a photography website as well. His chosen subject is microphotography, especially of living things. Perhaps the best place to start is his latest post, where he uses fluorescent dyes to take pictures of a rotting flea embryo. Other favorites are shells of microscopic crustaceans, colorful plant seed fluorescence and mosquito larva in polarized light. He has also made a video, and explains the process here.
The BBC has captured footage of golden eagles hunting reindeer calves in northern Finland, confirming Sami reports. For more about the Sami, you can watch this series of videos, which cover a wide range of subjects, among them the language, arts and crafts, religion and music. And here is more about Sami reindeer folklore.
"With most animals, males duke it out and the winner gets the girls," says Holekamp. "But with hyenas, females have 100 percent say." They decide when and under what conditions they will tolerate deferential sperm donors. At age 2 or 3 a male leaves his natal clan and wanders off to beg acceptance into another clan. After vicious rejections, he eventually succeeds and reaps his reward: brutal harassment as the clan's nadir, one of the last in line for food and sex. This probation, which biologists call "endurance rivalry," is a test, Holekamp explains: "The guy who can stick it out the longest wins." The trial lasts about two years, after which some females may grant him access. "You do not want to be a male hyena," Holekamp says.-From an article in Smithsonian Magazine, Who's Laughing Now? Professor Holekamp's hyena site. Also, hyena pictures and The Hyena Pages, a fine site about this fascinating animal.
Like squid? What about the good ol' octopus? The cuttlefish and nautilus? If you answered yes to these questions Dr. James B. Wood's Cephalopod Page is your go-to site, with information on and pictures of 25+ species of cephalopods including the aptly named (I'm sure) vampire squid from hell. The site also hosts many articles. Not sure where you stand on the coolness of cephalopods? Why don't you start by watching this video of an octopus squeezing through a one inch hole (previously on MetaFilter).
The Nature of Normal Human Variety A talk with Dr. Armand Leroi (his website). "Almost uniquely among modern scientific problems [the problem of normal human variety] is a problem that we can apprehend as we walk down the street. We live in an age now where the deepest scientific problems are buried away from our immediate perception. They concern the origin of the universe. They concern the relationships of subatomic particles. They concern the nature and structure of the human genome. Nobody can see these things without large bits of expensive equipment. But when I consider the problem of human variety I feel as Aristotle must have felt when he first walked down to the shore at Lesvos for the first time. The world is new again."
