The
American manatee occurs in waters that have a salinity ranging
from saltwater to freshwater and that have sufficient depth
(1.5 m (5') to usually less than 6 m (20')). It may be found
in canals, rivers, estuarine habitats, offshore cayes, coastal
lagoons and saltwater bays. Individual manatees on occasion
have been observed as much as 6 km (3.7 mi) off the Florida
Gulf coast and up to 15 km (9.3 mi) off the Guyana coast.
The American manatee also seems to prefer water temperatures
above about 20 deg C. Although they can endure water as
cold as 13.5 deg C.
