The West Indian manatee, often referred to as a “sea cow,” is a large, gentle marine mammal known for its slow movements. These creatures frequently inhabit shallow rivers, estuaries, and coastal waters where they graze on submerged vegetation. Manatees are federally protected due to their vulnerability to human-related threats. It is strictly prohibited by law to approach, harass, or touch a manatee in the wild to safeguard its health, behavior, and long-term survival.
Legal Protections for Manatees
Manatees are protected under multiple layers of legislation, making harassment illegal at both the state and federal levels. The primary federal laws are the Marine Mammal Protection Act (MMPA) of 1972 and the Endangered Species Act (ESA) of 1973, which protect the manatee as a marine mammal and a threatened species. These acts define harassment as any act of pursuit, torment, or annoyance that could injure a marine mammal or disrupt its behavioral patterns, such as migration, breeding, and feeding. This definition covers direct physical contact, but also includes actions like chasing a manatee with a vessel or trying to separate a mother and calf.
The state of Florida provides additional safeguards through the Florida Manatee Sanctuary Act of 1978, which designates the entire state as a refuge. This state legislation reinforces the prohibition against annoying, molesting, or disturbing manatees within Florida’s waters.
How Human Contact Harms Manatee Behavior and Health
Touching a manatee directly threatens its survival by altering its natural behaviors, a process known as habituation. When manatees become accustomed to human contact or feeding, they lose their natural wariness of people and boats. This lack of caution dramatically increases their risk of injury or death from collisions with boat propellers, which are the leading human-related cause of manatee fatalities.
Physical contact and close proximity interrupt life functions, such as resting, foraging, or nursing. Manatees need undisturbed time to rest and conserve energy, especially during the winter months when they congregate in warm-water refuges to avoid cold stress syndrome. Repeated disturbances force them to move repeatedly, causing them to expend energy reserves.
Direct contact also creates stress, which can suppress the manatee’s immune system, making it more susceptible to disease. Harassment can also lead to the separation of a mother and her dependent calf, which relies on its mother for up to two years to learn essential survival skills. Physical interaction introduces the potential for disease transmission between humans and manatees.
Penalties for Breaking Manatee Interaction Laws
Violating manatee protection laws can result in severe legal consequences. Enforcement is handled by federal agencies like the U.S. Fish and Wildlife Service and state agencies such as the Florida Fish and Wildlife Conservation Commission. Any activity that disrupts a manatee’s normal behavior is considered a violation.
Under federal protection acts, harassment can lead to civil penalties, criminal prosecution, and substantial fines. Violations of federal laws, such as the Endangered Species Act or the Marine Mammal Protection Act, are punishable by fines up to $100,000 and a maximum of one year in federal prison. Violating state laws, like the Florida Manatee Sanctuary Act, can result in a fine up to $500 and up to 60 days of imprisonment.
Safe and Ethical Manatee Viewing
The best way to appreciate manatees is through passive observation from a respectful distance. This approach allows the manatees to continue their natural behaviors without disturbance. When operating a vessel, wear polarized sunglasses to help spot manatees underwater and look for circular wave patterns, known as “footprints,” that a swimming manatee creates on the surface.
If a manatee approaches you in the water, the correct response is to remain still and allow the animal to pass on its own terms. You should never pursue, chase, or attempt to surround a manatee, whether swimming, snorkeling, or paddling a kayak. Maintain a distance of at least two kayak lengths or 50 feet whenever possible, and move away if the animal reacts to your presence. It is also illegal and harmful to offer manatees food or water, as this reinforces habituation to humans. If you encounter an injured, entangled, or harassed manatee, immediately report the incident to wildlife authorities.
