Manatees usually cruise at about 3 to 5 miles per hour (5 to 8 km/h), and often move even slower while feeding. When startled, they can sprint at up to roughly 15 miles per hour (about 25 km/h) for short distances. They swim by moving their broad, paddle-shaped tail up and down and steer with their flippers.

Watch one grazing on a grass flat or resting in a spring run and you could easily believe it never moves faster than a drifting log. But a manatee that is startled, chased or in a hurry can surprise you. That big, round tail is a powerful engine, and for a short distance a manatee can move fast enough to leave a swimmer far behind. Here is what we know about manatee speed, how they swim, and why their slow everyday pace makes them so vulnerable to boats. Cruising speed: slow by design Most of the time a manatee moves at walking pace or slower. A manatee travelling from one place to another usually cruises at around 3 to 5 miles per hour, or 5 to 8 kilometres per hour. That is about the speed of a person walking briskly. While feeding, a manatee may move only a body length or two at a time as it grazes along a bed of seagrass, and while resting it may barely move at all, drifting with the current or lying on the bottom. That slow pace isn't laziness. It reflects the way manatees live. They are plant eaters with an unusually low metabolic rate for a mammal of their size. Plants are low in energy, so a manatee needs to eat a great deal of them, and it can't afford to burn energy swimming fast when it doesn't need to. Our page on the [manatee diet](/manatee-diet/) explains how much they eat. They also have almost no natural predators as adults, as we describe on our [manatee predators](/manatee-predators/) page, so they have had little evolutionary pressure to be fast. A slow, steady, energy-saving lifestyle has served them well for millions of years. ![Manatee driving forward with its paddle tail, showing how fast a manatee can swim in a burst](https://thesea.org/wp-content/uploads/how-fast-can-a-manatee-swim-1-thesea-org-by-blane-perun.webp)Manatee driving forward with its paddle tail, showing how fast a manatee can swim in a burst Burst speed: faster than you'd think Short sprints of up to about 15 mph. When a manatee is startled, by a boat, a sudden noise or a swimmer getting too close, it can accelerate quickly. In short bursts, manatees are generally reported to reach speeds of up to about 15 miles per hour (roughly 25 km/h), and some sources quote figures up to 20 mph. Sprints like this last only seconds or a short distance; they are an escape response, not a way of travelling. Over weeks, though, slow cruising adds up, and tagged manatees have covered hundreds of miles, as our page on [manatee tracking](/manatee-tracking/) shows. You can sometimes see this in the wild. A manatee resting near the surface that is disturbed will often dive with a powerful tail stroke that leaves a big swirl, or “footprint”, on the surface, and be gone in a moment. Males in a mating herd chasing a female can also move surprisingly fast and churn the water, as our page on [manatee mating](/manatee-mating/) describes. Playful manatees, especially younger ones, sometimes do barrel rolls and quick turns as well. 3–5 mphNormal cruising speed ~15 mphShort burst speed when startled 0 mphMuch of the day: resting on the bottom How manatees swim A paddle tail for power, flippers for control. The manatee's power comes from its tail. Unlike a fish, which sweeps its tail from side to side, a manatee moves its tail up and down, the same way whales and dolphins do. The tail itself is broad, flat and rounded, shaped like a paddle or a beaver's tail. That shape is one of the easiest ways to tell a manatee from its close relative, the dugong, which has a notched, whale-like tail. Our guide to [dugongs vs manatees](/dugong-vs-manatee/) explains the difference. A paddle tail is good for slow, controlled movement and for quick acceleration from a standstill, which suits life in shallow, cluttered water; a fluke-shaped tail is better for efficient cruising in open water. The front flippers are used mainly for steering, stabilising and fine control rather than for power. Manatees also use their flippers to “walk” along the bottom, to push off, to hold food and even to hug each other. Each flipper contains the bones of a hand and fingers, and West Indian and African manatees have three or four small fingernails at the tip, a reminder of their land-mammal ancestry, which we cover on our [manatee skeleton](/manatee-skeleton/) page. Buoyancy matters too. With heavy, dense bones as ballast and long lungs that run along the back, a manatee can adjust how high or low it sits in the water just by changing how much air it holds. That means it can rise, sink and hover without spending energy on swimming, which helps explain why so much of a manatee's movement looks effortless. | Animal | Typical cruising speed | Short burst speed | Tail action | | ------ | ---------------------- | ----------------- | ----------- | | Manatee | 3–5 mph (5–8 km/h) | Up to ~15 mph (~25 km/h) | Up and down, round paddle | | Dugong | Slow, similar to manatees | Faster in bursts | Up and down, notched fluke | | Bottlenose dolphin | Several mph | Over 20 mph | Up and down, fluke | | Elite human swimmer | — | About 5 mph over 50 m | Arms and legs | Long-distance travel Slow, but they cover a lot of ground. Slow doesn't mean stay-at-home. Florida manatees make seasonal migrations, moving into warm-water refuges in winter and spreading out along the coast in summer. Over a season, some individuals travel hundreds of miles. Manatees from Florida's Atlantic coast regularly travel north into Georgia and the Carolinas in summer, and on the Gulf side some move west along the Panhandle and beyond. The most famous long-distance traveller was a male manatee nicknamed Chessie, first found in Chesapeake Bay in the 1990s. Researchers fitted him with a satellite tag, and in later summers he was tracked travelling up the Atlantic coast, at one point reaching as far north as Rhode Island, before returning to Florida for the winter. Journeys like that show that even at a few miles an hour, a manatee that keeps moving can cover a remarkable distance. Our page on [manatee habitat](/manatee-habitat/) covers the range and seasonal movements in more detail. ![Manatee back surfacing as a fast boat passes, why how fast a manatee can swim matters](https://thesea.org/wp-content/uploads/how-fast-can-a-manatee-swim-2-thesea-org-by-blane-perun.webp)Manatee back surfacing as a fast boat passes, why how fast a manatee can swim matters Why speed matters: manatees and boats A slow animal near the surface can't get out of the way. The biggest practical consequence of the manatee's slow pace is its vulnerability to boats. A manatee resting or feeding near the surface, or rising to breathe, may not hear a fast-approaching boat in time, and even when it does, it may not be able to dive or move away quickly enough. Studies of manatee hearing suggest that they hear higher-frequency sounds better than the low hum of a slow-moving engine, and boat noise is easily masked in shallow, noisy water. A powerboat travelling at speed covers ground many times faster than a manatee can swim, even at its best burst speed. That is why so many of Florida's waterways have posted manatee protection zones, where boats must travel at slow speed or idle speed, especially in shallow areas, canals and near warm-water sites. Collisions with watercraft are the largest single human-caused cause of manatee deaths in Florida, and most adult manatees carry scars from propellers or hulls. When boats slow down, manatees have time to react, and when they are struck, the injuries are less likely to be fatal. What I keep in mind around manatees Slow animals need everyone else to slow down. I live in Southwest Florida, where manatees share the canals, rivers and bays with a lot of boats, and in my view the speed question is really a boating question. Knowing that a manatee normally moves at walking pace changes how you think about a no-wake zone. If you are in a boat, the manatee isn't going to get out of your way in time; you have to give it the chance. I'd wear polarized sunglasses on the water, keep a lookout in the shallows, and treat every posted slow zone as non-negotiable, even when I can't see any manatees. The same logic applies to swimmers, snorkelers and paddlers. A manatee that is approached too fast or too closely may bolt, and a startled manatee can turn hard with a single tail stroke that rocks a kayak or bumps a swimmer. Let the animal set the pace. If you'd like to see manatees from the water, our guides to [kayaking with manatees](/kayaking-with-manatees/) and [snorkeling with manatees in Crystal River](/crystal-river-manatee-snorkeling/) explain how to do it responsibly. Spot a moving manatee Look for a smooth, round “footprint” on calm water, a line of bubbles, or a snout breaking the surface. A swirl that suddenly appears often marks a manatee that has just dived with a strong tail stroke. Learn more in [What Is a Manatee?](/what-is-a-manatee/) Are some manatees faster than others? Size, age and species all play a part. There is little hard data comparing speeds between individuals or species, but some patterns make sense. Calves are smaller and less powerful, and they have to keep up with their mothers, so mothers tend to travel at a pace the calf can manage. Large adults have more power but also more mass to move. The three living manatee species, the West Indian, Amazonian and African manatees, all share the same basic body plan and paddle tail, so their speeds are thought to be broadly similar. The Amazonian manatee, which lives entirely in fresh water and is the smallest, has to contend with river currents and seasonal floods; you can read more about it on our [Amazonian manatee](/amazonian-manatee/) page. The bottom line is that manatees are built for efficiency, not speed. They spend most of their lives moving slowly, saving energy and avoiding effort, and they keep a burst of speed in reserve for emergencies. In a world without powerboats, that strategy worked perfectly. Today, it means that the animals rely on us to slow down for them. ![Manatee mother and calf cruising slowly, the usual pace of how fast a manatee can swim](https://thesea.org/wp-content/uploads/how-fast-can-a-manatee-swim-3-thesea-org-by-blane-perun.webp)Manatee mother and calf cruising slowly, the usual pace of how fast a manatee can swim Frequently asked questions How fast does a manatee swim in mph? Usually about 3 to 5 mph, with brief bursts of up to around 15 mph when startled. How fast can a manatee swim in km/h? About 5 to 8 km/h when cruising, and up to roughly 25 km/h in short sprints. Can a person outswim a manatee? At cruising speed, a strong swimmer might keep up briefly, but no human can match a manatee's burst speed. Why are manatees so slow? They eat low-energy plants, have a low metabolic rate and face few natural predators, so they save energy by moving slowly. How do manatees swim? They move their paddle-shaped tail up and down for power and use their flippers to steer. How far can a manatee travel? Hundreds of miles in a season. One tagged manatee, Chessie, travelled from Florida as far north as Rhode Island. Why can't manatees avoid boats? They move slowly, rest near the surface and may not hear a fast boat in time, so boats must slow down in manatee zones.
