Someone with too much time on their hands and too few brains mutilated a manatee in Biscayne National Park the other day. The mammal, also known by the less-than-flattering name "sea cow," is considered endangered under the Endangered Species Act, with a minimum population of 3,200 individuals, as of 2002, according to the Manatee Observation and Education Center.
    Today the population is down by at least one, as a butchered manatee was discovered this past Friday in the park's waters. Rangers say the manatee's throat was slashed and its fins cut off. If the responsible person is found and successfully prosecuted, they could face a year in jail and a $100,000 fine.
