There are still a few thousand individuals in each manatee species, but their population estimates are often hindered by scant data, and even the best-case scenarios don't provide much buffer from the threats they face. Outside the United States, manatee population and abundance estimates are less certain. Manatees can become confused by multiple boats, sometimes swimming away from one and into the path of another. Increases in manatee populations and improvements in their habitats led the U.S. Manatees cannot rely on blubber to stay warm during winter like other sea mammals. Watercraft collisions are the main threat to Florida manatees, but they're also a risk for manatees everywhere. Manatees are still vulnerable to extinction throughout their range, and despite some recent conservation success in Florida, they aren't well-suited for quick recoveries due to their low reproductive rate. Your help will be especially valuable if you remove discarded fishing line, plastic bags, or other items that pose a danger for manatees. Development also raises the demand for groundwater supplies, threatening the warm springs where cold-intolerant manatees seek refuge in winter. 10 Amazing but Endangered Shark Species: How Many Do You Know?
