Most of these are canals or boat basins where warmer water temperatures persist as temperatures in adjacent bays and rivers decline. During mild winter periods, manatees move to nearby grassbeds to feed. As water temperatures rise in spring, manatees disperse from winter aggregation areas. While some remain near their winter refuges, others undertake extensive travels along the coast and far up rivers and canals. They usually occur alone or in pairs, although interacting groups of five to ten animals are not unusual.
Shallow grass beds with ready access to deep channels are preferred feeding areas.
In estuarine and brackish areas, natural and artificial fresh water sources are sought by manatees. Continue on to Trophic Relationships.
