Baby Manatee Rescued From Florida Inlet Dies (VIDEO)

A baby manatee rescued from Sebastian Inlet at Melbourne Beach in Florida has died, according to Central Florida News 13.

The young female calf had been responding well to treatment at SeaWorld Orlando on Wednesday, The Orlando Sentinel reported. Officials believed the manatee was orphaned, but were unsure of exactly why.

"Although she appeared to be stable upon arrival, oftentimes there are underlying factors masking the real problem affecting the animal," a senior communications manager for SeaWorld Parks and Entertainment told CFNews13.

The 3 to 6-month-old calf, which was about 4 feet long, was brought to the facility in a joint effort between SeaWorld's animal rescue team and the Florida Fish and Wildlife Conservation Commission, according to UPI.

SeaWorld has recently been the target of a number of animal rights activists who have accused the parks of enslaving whales and other marine life. PETA has been outspoken on the issue, even enlisting the help of Bob Barker to condemn SeaWorld and discourage potential visitors.
