River Otter
Lontra canadensis
A sleek freshwater predator that swims, dives, and travels through Florida wetlands with speed and agility.
North American River Otters use rivers, lakes, marshes, swamps, and connected estuaries across Florida. Clean water, healthy fish populations, and vegetated shorelines support their territories.
They are powerful swimmers and often travel overland between water bodies, especially at night or during quiet morning hours.

Safety Information:
Keep a respectful distance and never feed an otter. Bring pets indoors near repeated sightings. Back away slowly if an otter approaches or acts defensively.
Benefits to Property:
Indicates a functioning aquatic food web and helps regulate fish, crayfish, and other prey populations.

May take fish from ornamental ponds, leave scent-marking sites, or shelter beneath quiet shoreline structures. Secure pond stock without trapping the animal.
Fun Fact:
- Otters close their ears and nostrils underwater.
- Dense fur traps insulating air.
- They use both water routes and overland trails.
Wildlife Laws:
