SARASOTA, Fla. -- Back in 1902, a scientist examining the smooth, grapefruit-size brain of a manatee remarked that the organ's unwrinkled surface resembled that of the brain of an idiot. Ever since then, manatees have generally been considered incapable of doing anything more complicated than chewing sea grass. But Hugh, a manatee in a tank at a Florida marine laboratory, doesn't seem like a dimwit. When a buzzer sounds, the speed bump-shaped mammal slowly flips his 1,300 pounds and aims a...

NEW YORK (Reuters) - New Yorkers are known to head south to vacation, but at least one Floridian had an urge to come north to see the big city. Marine preservationists said a manatee had swam up the Hudson River past Manhattan's Chelsea neighborhood and then 100 miles upstate. It was the first confirmed sighting of the mammal in New York in 10 years. The manatee was filmed by boaters late last month in New Jersey and Delaware and has since been spotted by at least five different...

ORANGE CITY, Fla. -- Sweet Gum was fatally injured by a racing boater. Her calf, Rachel, was also killed by a boat near Lake Monroe, and so was her granddaughter, Ruby. This year has been a hard one for the state's endangered manatee population. Despite educational programs and campaigns targeting boaters, the number of confirmed manatee deaths in Florida jumped 30 percent during the first 11 months of 2005, according to state officials. The Florida Fish and Wildlife Commission estimated 366...

GAINESVILLE, Fla. - For Florida manatees, the eyes may have it, say University of Florida researchers studying whether the mammals' unusually thick tear film helps protect against disease and could be used to gauge the endangered sea cows' ability to fight stress from cold water temperatures. Manatees depend on both natural and artificial warm water refuges like those found near coal-burning power plants to survive cold winters. As older coal-burning power plants are phased out in the next...

GAINESVILLE, Fla. (AP) -- Despite their huge size, the bones of manatees are as brittle as fine porcelain, making them extremely vulnerable to being broken when struck by a boat, a University of Florida researchers said Thursday. The surprising findings could ultimately change public policy for the management of Florida's waterways, said Roger Reep, a professor of the UF College of Veterinary Medicine's physiological sciences department. "When you pick up a manatee rib, it's much denser...

The West Indian Manatee, Trichechus manatus, is the largest surviving member of the aquatic mammal order Sirenia. It is found along the coastal waters of the West Indies, generally in shallow areas. However, it is known to withstand large changes in water salinity, and so have also been found in shallow rivers and estuaries. These animals are limited to the tropics and subtropics due to an extremely low metabolic rate and lack of thick insulating body fat. Although in the summer they can be...
