Page "Manatee" Paragraph 18

The West Indian manatee migrates into Florida rivers, such as the Crystal, the Homosassa, and the Chassahowitzka Rivers.

The headsprings of these rivers maintain a 22 ° C ( 72 ° F ) temperature year round.

During November to March, approximately 400 West Indian manatees ( according to the National Wildlife Refuge ) congregate in the rivers in Citrus County, Florida.
