A manatee, a large aquatic mammal, has been spotted several times in the Hudson River. It was seen off the coast of lower Manhattan and as far north as Westchester.
Manatees, which are classified as an endangered species, usually eat plants, so they pose no threats to swimmers, boaters, or fishermen.
Still, given the manatee's enormous size, I wonder if it's spooking the fish in the Hudson River.
