Today, we show some love to the ocean's chillest stars. Forget dolphins doing flips or sharks stealing headlines—manatees win hearts by doing, well, almost nothing. And that's the charm. They are found in the warm coastal waters of the Caribbean Sea, the Gulf of Mexico, the Amazon Basin and West Africa. They can weigh about 550 kilograms, yet their diet is strictly vegetarian. These whiskered mammals are slow swimmers in a fast-paced world. They cruise at around 8 kilometres per hour—great for relaxing, not so great when speedboats come charging through. That's why 'no-wake zones,' or sections of waterways with a strict speed limit, are there to keep manatees safe.

Despite the 'sea cow' nickname, these marine animals are closer genetically to elephants than cattle. And like elephants, they're gentle giants with no interest in picking fights. Their biggest battles are against human-made threats: pollution, habitat loss and boat collisions. So, what can you do? Support conservation, spread the word and if you're boating in their waters, channel your inner manatee and take it slow.
