(Aug. 23) - An unknown creature caught on video lurking beneath a lagoon in West Palm Beach, Fla., has the city wondering what it could be, WPTV.com reported Sunday.
The mysterious creature was videotaped by the LagoonKeepers.org, a group that patrols the city's waterways in search of debris. "I hollered out ... and said, 'What is that?' We followed it, started taking video," said Greg Reynolds, a member of the group.

Don Serrano, who was with Reynolds, said the creature was "different, very different."
Reynolds said he and Serrano tried to catch up to it, but that every time they would get close to it, "it would just disappear." He named the creature "the elusive muck monster."
Thomas Reinert, a marine biologist who works for the Florida Fish and Wildlife Conservation Commission, studied the video and said the creature appears to be moving in one direction and that it was not breaking the surface.
"Typically dolphins break the surface, sea turtles, manatee, a large school of fish. If it were a shark at that level, you would see a fin," the expert told WPTV.
"I can't definitely say what it is," he added.
