VOLUSIA COUNTY, Fla. — A sick manatee pulled from the Indian River near Edgewater was in critical condition Sunday afternoon, SeaWorld says.

The 715-pound male is suffering from cold stress, a SeaWorld spokesperson said.

It was rescued by volunteers and crews from SeaWorld and Volusia County Beach Safety. It was transported to a SeaWorld rehabilitation facility, where it's being monitored around the clock.

Manatees can't tolerate water temperatures below 68 degrees for very long, so during the winter months, they typically move from waters along the coasts to warmer waters, such as springs and power plant discharge canals.

If humans get too close to them in their natural habitat, they can disrupt manatees' normal behavior patterns, which could prompt them to leave warm-water areas, the Florida Fish and Wildlife Conservation Commission says.

Manatees are listed as threatened under the Endangered Species Act and federally protected. If you spot a sick or injured manatee, call the FWC's Wildlife Alert number toll-free at 1-888-404-FWCC, or #FWC or *FWC on a mobile phone. You can also text Tip@MyFWC.com.
