You've met the front of Tiktaalik roseae , the fish-like creature that fills an important gap between fish and four-legged, land-based animals. Now, the hindquarters of the 375-million-year-old fossil are having their close-up moment, and they're showing a pelvis that marks it farther along the evolutionary track from fin to limb. Discovered in the Canadian Arctic in 2004, and introduced to the scientific world two years later, Tiktaalik roseae demonstrates the predictive power of Darwin's theory of evolution -- a transitional creature found on the timeline precisely where the theory assumed it ought to be. Tiktaalik, an Inuit word for “large, freshwater fish,” had a skeletal structure that likely allowed it to support itself with its front and back fins, and “walk” with them, at least in shallow waters, according to a study published Monday in the journal Proceedings of the National Academy of Sciences.

Scientists have discovered more than 180 species of biofluorescent fish that glow in neon shades of blue, red, orange and green -- most of them hiding out in tropical coral reefs. Some of the fish glow just around their eyes. Others have intricate fluorescent patterns on their bellies or backs. And some of the fish glow all the way through their bodies. If you slice a false moray eel like a salami and shine a blue light on it, the entire cross-section would illuminate. And it turns out that reef fish that are the most mottled and brown and difficult to see are the ones that tend to fluoresce the most.

A school of carnivorous fish attacked hundreds of Argentines cooling off in a river near the city of Rosario, sending at least 70 to local clinics and emergency rooms for treatment. The attack by palometas, a type of piranha, occurred as city dwellers attempted to escape the 100-degree heat of Christmas Day in the Southern Hemisphere's summer season. "There were some people that the fish literally had torn bits of flesh from," a medical official at the scene, Gustavo Centurion, was quoted as saying by the Latin Times newspaper.

There is life after basketball, and Ben Howland has found it. There were the two weeks of fly-fishing in Montana and Wyoming this summer, with some spectacular success, unless you were a rainbow, cutthroat, brook or brown. "Oh, man," Howland says. "I never had time for that before. I'll send you some pictures. " And he does. There has been the kind of family time that a UCLA basketball coach just doesn't get. This year's Christmas card shows family among the swaying palm trees of Maui, with grandson Little Ben stealing the photo.

Re "The lessons of Bell," Editorial, Dec. 11 Where's the justice? Former Bell administrators Angela Spaccia and Robert Rizzo were found guilty of enriching themselves at taxpayer expense and face jail time, as they should. But what about the Wall Street moguls who did much worse and brought the entire U.S. economy to the edge of collapse, costing billions upon billions of dollars? For the most part, they got off with some fines - that represented a few weeks of revenue - and are walking around free.

Ocean acidification could alter the behavior of fish and make them more anxious, a new study says. The finding came in an experiment by researchers interested in the neurological effects of the shift in the chemistry of seawater that is happening as the ocean takes up carbon dioxide that has built up in the Earth's atmosphere from human activity. In a laboratory, scientists put one group of young rockfish , a common species along the California coast, in normal seawater and put another group of the fish in water with the lower pH the ocean is predicted to reach in about 100 years.

All it took to reach a more realistic estimate of how much fish is being harvested from the sea was one scientist with an Internet connection and an inquisitive mind. Researchers at the University of British Columbia used satellite imagery from Google Earth to discover that large fish traps in the Persian Gulf could be netting nearly six times more fish than official statistics report. The study began with a PhD student messing around on the Internet. ”I was just playing around with Google Earth, doing what most people do when they first get on, which is try to find their house,” said Dalal Al-Abdulrazzak, a doctoral student at the university's Fisheries Center and lead author of the study.

JOHANNESBURG, South Africa -- Nations whose fleets fish for bluefin tuna and sharks ended a meeting in South Africa without reaching agreement on action to protect critically endangered species, environmentalist groups said. A proposal to ban fishing of the critically endangered porbeagle shark was blocked at the eight-day meeting in Cape Town of the International Commission for the Conservation of Atlantic Tunas (ICCAT), a body consisting of major Atlantic tuna and shark fishing nations, as well as other Atlantic coast nations, according to environmentalists who observed the meeting.
