World Manatee Day, celebrated on September 7, honors the gentle, slow-moving sea cows that graze the seagrass meadows of warm coastal waters. Manatees are large, rounded, and utterly peaceable herbivores, more closely related to elephants than to any dolphin or seal, and their unhurried lives leave them vulnerable to the busy world we have built along their shores.

Meet the sea cow

Manatees can weigh over a thousand pounds yet survive entirely on plants, munching their way through huge quantities of seagrass and freshwater vegetation each day. They surface every few minutes to breathe, drift through shallow rivers and estuaries, and gather in warm-water springs when temperatures drop. Their placid nature is part of their charm and part of their peril: they simply do not move fast enough to dodge trouble.

Watch your wake in their waters

Collisions with boats are one of the greatest dangers manatees face, and nearly every wild manatee carries the scars of a propeller strike. If you boat in manatee country, obey posted slow-speed and no-wake zones, wear polarized sunglasses to spot the telltale swirl of a surfacing animal, and stay in marked channels where the water is deep enough. Slowing down costs you a few minutes and can save an animal’s life.

Look but do not disturb

Manatees are protected, and the rules exist because our attention can harm them. Never chase, feed, or give water to a wild manatee, since doing so lures them toward the docks and boats that hurt them. Watch quietly from a distance and let any animal approach on its own terms. If you paddle a kayak or paddleboard through their habitat, you get a front-row seat without an engine to endanger them.

Protect the seagrass

Manatees live or die by the health of the seagrass beds they graze, and those meadows suffer when pollution and runoff cloud the water. Cutting fertilizer use near waterways, supporting clean-water efforts, and keeping trash and fishing line out of the shallows all protect the buffet manatees depend on. Report any injured or entangled manatee to your local wildlife hotline rather than intervening yourself.

Manatees reward a slower, gentler way of sharing the water. Ease off the throttle, keep your distance, and help protect the seagrass — small courtesies that let these gentle giants keep grazing the warm shallows in peace.

How to celebrate

  1. 1
    Meet the sea cow

    Learn that manatees are plant-eating relatives of elephants that graze seagrass and surface every few minutes to breathe. Their placid pace is both their charm and their peril. It is an easy animal to admire.

  2. 2
    Watch your wake

    If you boat in manatee country, obey slow-speed and no-wake zones and stay in marked channels. Wear polarized sunglasses to spot a surfacing animal's swirl. Slowing down can save a life.

  3. 3
    Look but never feed

    Never chase, feed, or give water to a wild manatee, since it lures them toward dangerous docks and boats. Watch quietly from a distance and let them approach. A kayak lets you share their water without an engine.

  4. 4
    Protect the seagrass

    Cut fertilizer use near waterways and support clean-water efforts to keep seagrass meadows healthy. Keep trash and fishing line out of the shallows. Report any injured manatee to a wildlife hotline instead of intervening.
