Manatees are adorable giants with a gentle demeanor and an endearing curiosity. Most of the day, you can catch these large, fully aquatic, herbivorous mammals either sleeping or eating. Sadly, issues such as habitat loss and run-ins with boats have endangered them. In fact, it’s estimated that only about 7,634 to 10,434 West Indian manatees exist. The Amazonian manatee population count is not available, but scientists believe their numbers are not large either. It’s sad that such an incredible creature is in danger of going extinct. On this list, we are going to bring awareness to this incredible animal. These are 25 manatee facts that show how fascinating they are.

In what may seem somewhat counter-intuitive, power plant effluents play a critical role in manatee protection. Manatees use the plant effluents as winter warm water refugia which protect manatees during cold spells.

A population for manatees world wide is difficult to acquire. However, estimates state that there are between 7,634 and 10,434 West Indian manatees. No population estimate for the Amazonian manatee is available.

Female manatees usually only have one calf every two to five years, and it's estimated that manatees can live to about 60 years. However, research by the Florida Fish and Wildlife Conservation Commission revealed that few manatees were living past the age of 30, well below their estimated life expectancy.

Manatees can hold their breath for up to 20 minutes, and when they do take a breath, 90 percent of the air in their lungs is replaced. (To compare, a human replaces about 10 percent of air when he/she breathes.)

In spite of their appearance, manatees have minimal fat protection which makes them susceptible to cold temperatures. In 2010, Florida saw the death of around 246 manatees due to cold stress from the abnormally cold winter.

Manatees are herbivores and eat about 10 to 15 percent of their body weight every day. With some manatees weighing around 800 to 1,200 pounds, that’s a lot of veggies in a day.
