How to spot the Manatee when scuba diving
Trichechus
Southeastern US (Florida, migrating north seasonally), Gulf of Mexico coast, Caribbean islands, Central America, and northern South America (down to Brazil). Divided into Florida and Antillean subspecies.
Best time in Florida is winter (November-March) when colder ocean temperatures drive them to aggregate in warmer freshwater springs and power plant outflows. Can be seen year-round in some areas, but concentrations are highest in winter.
Prefer warm water; cannot tolerate temps below ~20°C (68°F) for extended periods. Seek warm water refuges in winter.
Shallow coastal waters, rivers, estuaries, canals, and especially freshwater springs (Florida – e.g., Crystal River, Homosassa Springs). Encounters are primarily via snorkeling or kayaking. Regulations mandate passive observation (no touching, chasing, feeding, diving down onto them). Follow operator guidelines and mandatory briefings (like FWC video in Florida).
