In the United States, the West Indian manatee is federally listed as Threatened, not Endangered. The U.S. Fish and Wildlife Service (USFWS) proposed in January 2025 to list Florida manatees as Threatened and Antillean manatees as Endangered separately, but its proposal remains a proposed rule in the records reviewed. Florida and Antillean manatees face different ranges and threats, and both remain in need of protection.
Manatee conservation status at a glance
“Endangered” can mean a legal category or be used informally to describe an animal at risk. This article focuses on the U.S. federal status established by USFWS; it does not establish current global or IUCN classifications.

| Subspecies | Range | Current U.S. federal status | 2025 USFWS proposal | Key concerns |
|---|---|---|---|---|
| Florida manatee (Trichechus manatus latirostris) | Florida and nearby coastal waters, with seasonal range changes | Included in the West Indian manatee’s species-level listing as Threatened | Threatened, with proposed Section 4(d) protections | Boat collisions, forage and warm-water habitat loss, harmful algal blooms, cold stress, entanglement, and water-control structures |
| Antillean manatee (Trichechus manatus manatus) | Caribbean and Central America, extending toward northeastern Brazil | Included in the West Indian manatee’s species-level listing as Threatened | Endangered | Habitat loss, collisions, harassment, poaching, fishing gear and marine debris; available information indicates declines across much of its range |
USFWS’s species profile identifies the West Indian manatee as federally protected under the Endangered Species Act (ESA) and the Marine Mammal Protection Act (MMPA). The proposed split should not be described as a finalized legal change. See the USFWS species profile and proposed rule.
What do “Threatened” and “Endangered” mean under U.S. law?
Under the ESA, an Endangered species is in danger of extinction throughout all or a significant portion of its range. A Threatened species is likely to become Endangered within the foreseeable future. These legal categories are not the same as a global scientific assessment or everyday descriptions of an animal’s condition.
#1 Best Overall
A Threatened listing does not mean a species is secure. USFWS describes the current West Indian manatee listing as Threatened while proposing different classifications for its two subspecies. Consult the USFWS FAQ for its explanation of the proposed distinction.
What is the current status of Florida manatees?
Florida manatees are the subspecies most commonly meant by “manatee” in the United States. They occupy the northern edge of the West Indian manatee’s range and depend on warm-water habitat during winter.
Why the 2017 downlisting did not mean recovery was complete
In 2017, USFWS changed the West Indian manatee’s federal classification from Endangered to Threatened. The change reflected progress in conservation and population conditions, but it did not remove ESA protection or mean that serious threats had ended.
What the 2025 proposal would change
USFWS proposed replacing the species-level listing with separate subspecies classifications:

- Antillean manatee: Endangered.
The proposal reflects differences in the subspecies’ ranges, habitat needs, and threats. USFWS’s proposal page still identifies the action as proposed. The latest regulatory agenda record reviewed describes the final determination as a long-term action with the next action to be determined; this does not rule out later docket activity. Recheck the official listing and docket before publication. See the proposed rule and regulatory agenda record.
How many Florida manatees are there?
The Florida Fish and Wildlife Conservation Commission (FWC) estimate cited by USFWS is 8,350–11,730 Florida manatees. USFWS’s FAQ identifies it as an FWC 2023 estimate. It is a range, not an exact head count.
Population estimates should be interpreted in context. Florida’s population has increased from historic low estimates, but abundance alone does not remove ongoing risks or establish the condition of every part of the range. The estimate is not directly comparable to a rough range-wide figure for the Antillean subspecies. See the USFWS FAQ.
Why the Antillean manatee is a particular concern
Antillean manatees occur across the Caribbean and Central America and toward northeastern Brazil. Their populations are spread across a broad range, and available information indicates abundance is declining in most of it.

The agency profile does not state a publication year for that figure, so it should not be treated as a dated census or a precise count. USFWS also identifies low genetic diversity among the concerns. See the USFWS Antillean manatee profile.
What are the main threats to manatees?
Boat collisions
Watercraft collisions can injure or kill manatees. Boaters can reduce risk by watching for animals, slowing down, and obeying posted manatee zones, especially in shallow water and near docks.
Rank #3
Loss of food and habitat
Loss or degradation of seagrass and other forage can leave manatees with less food. Coastal development, poor water quality, and harmful algal blooms also threaten habitat. The Florida starvation event associated with seagrass loss illustrates how habitat problems can affect manatees even without a collision.
Loss of warm-water refuges and cold stress
Florida manatees are cold-intolerant and use natural springs, power-plant outfalls, and passive thermal basins in cooler months. USFWS says they cannot tolerate temperatures below 68°F for extended periods. Reduced spring flow or loss of artificial warm-water sites can increase risk. This Florida-specific winter refuge concern should not be assumed to apply equally to Antillean manatees.
Fishing gear, water-control structures, and harassment
Entanglement in or ingestion of fishing gear and marine debris can harm manatees. Locks and other water-control structures can also cause injury or death. Harassment, including pursuing or feeding animals, can alter their behavior and expose them to additional danger.
Poaching and other pressures on Antillean manatees
USFWS identifies poaching, habitat alteration or loss, collisions, harassment, fishing gear, and marine debris as concerns for Antillean manatees. The relative importance of threats differs across their range, and information is incomplete in some areas.
Harmful algal blooms and climate change
Harmful algal blooms can harm or kill manatees. USFWS also identifies climate change among the threats to Florida manatees. These pressures can compound habitat and food problems; their effects vary by place and conditions.
What conservation is doing
USFWS recovery plans aim to reduce mortality and injury, protect habitat, and monitor manatee populations and habitat. The agency identifies the Florida Manatee Recovery Plan, Third Revision (2001), the Puerto Rican Population of the Antillean Manatee Recovery Plan (1986), and the South Florida Multi-Species Recovery Plan (1999). These are plan publication dates, not evidence that every action remains current.
Recommended Free Tools
Conservation priorities include protecting habitat, reducing collisions and entanglement, maintaining access to suitable warm-water refuges for Florida manatees, and improving population and habitat monitoring. Rescue and rehabilitation can help individual animals, but preventing the threats remains important.
How can the public help manatees?
If you operate a boat
- Look for manatees before starting the motor.
- Obey posted slow-speed, no-wake, and manatee-warning signs.
- Use extra caution in shallow water and around docks.
- Keep your distance; do not pursue or harass manatees.
- Polarized sunglasses can reduce glare and may help you see animals below the surface, but they do not guarantee detection.
- Report injured or distressed animals to the relevant state wildlife agency.
If you swim, paddle, or watch wildlife
- Observe from a distance and leave resting animals undisturbed.
- Do not touch, chase, corner, or play with a manatee.
- Never feed a manatee or give it fresh water; this can teach it to approach people and dangerous places such as docks.
- Follow local wildlife-viewing rules and report an animal in trouble.
If you fish
Keep fishing line, hooks, nets, and other debris out of the water. If you see an entangled manatee, report it to wildlife authorities rather than trying to restrain or free it yourself.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should I do if I see an injured or distressed manatee?
Contact the relevant state wildlife agency and provide the location and a brief description of the animal and its condition. Do not touch, feed, capture, or attempt to free it. In Florida, follow FWC reporting instructions.
Are manatees recovering?
Florida manatees have increased from historic low estimates, and conservation work has helped improve their outlook. However, collisions, habitat and forage loss, harmful algal blooms, cold stress, and vulnerable warm-water sites remain concerns. The Florida estimate cited by USFWS is useful context, not proof that manatees are safe.
For Antillean manatees, USFWS says abundance is declining in most of the range and provides only a rough wild-population estimate. The most accurate conclusion is that the West Indian manatee remains federally Threatened in the United States, while USFWS has proposed a separate Threatened listing for Florida manatees and Endangered listing for Antillean manatees.
FAQ
Are manatees endangered in the United States?
The current USFWS species profile identifies the West Indian manatee as federally Threatened, not Endangered. The agency proposed separate classifications for Florida and Antillean manatees in 2025, but the proposal should not be treated as final.
What is the difference between the Florida and Antillean manatee?
They are subspecies of the West Indian manatee with different ranges and conservation pressures. Florida manatees live in Florida and nearby coastal waters and rely on warm-water habitat in winter; Antillean manatees range across the Caribbean and Central America toward northeastern Brazil.
How many Florida manatees are there?
USFWS cites an FWC 2023 estimate of 8,350–11,730 Florida manatees. It is a range rather than an exact count.
Does feeding a manatee help it?
No. Feeding or giving a manatee fresh water can teach it to approach people and dangerous places such as docks. Observe from a distance and report an injured or distressed animal to wildlife authorities.
How can the public support manatee conservation?
Look before starting a boat, obey posted speed zones, use caution in shallow water, keep fishing gear out of the water, and never feed or harass manatees. Report injured, orphaned, entangled, distressed, or dead animals to the relevant state wildlife agency.
