The manatees return to Florida from as far away as Boston Harbor to avoid cold water.
Manatees were spotted in the Florida Greenland Waterway in mid August. They on the way back to Florida for the Winter!
Temperatures below 62 degrees are harmful to them so they seek the warmth of the Florida "Springs" which remain 72 degrees -year round.
Blue Springs is one of the largest gatherings and has had over 200 manatees at one time.
