Manatees have nostrils, not blowholes like other aquatic mammals, which close when underwater to keep water out and open when above water to breathe. [14] Although manatees can remain under water for extended periods, surfacing for air about every five minutes is common. [15] [16] The longest documented submergence of an Amazonian manatee in ...
Manatees (/ ˈ m æ n ə t iː z /, family Trichechidae, genus Trichechus) are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows.There are three accepted living species of Trichechidae, representing three of the four living species in the order Sirenia: the Amazonian manatee (Trichechus inunguis), the West Indian manatee (Trichechus manatus), and the West ...
Manatees can also inhale these brevotoxins from the surface of the water as they come up for air, leading to respiratory symptoms and even drowning. [75] Manatee die-offs from exposure to red tide toxins were recorded by the Florida Fish and Wildlife Conservation Commission in southwest Florida in 2002, 2003, 2005, 2007, and 2013.
The range-wide minimum known population is estimated to be at least 13,000 manatees, with more than 6,300 in Florida. When aerial surveys began in 1991, there were only an estimated 1,267 manatees in Florida, meaning that the last 25 years has seen a 400 percent increase in the species population in that state.

There is so much to see and learn at this Florida-based laboratory and aquarium. To start, you can see a whole host of magical marine creatures up close and personal, thanks to its 135,000-gallon ...
[11] [25] Consequently, Florida manatees seek out warm-water refuges during the winter, concentrated primarily along the Florida peninsula. [26] Many of these refuges are artificial, created by the runoff from nearby power plants. [4] In contrast, the Antillean manatee is less susceptible to cold-induced stress due to the warmer waters across ...
Prolonged exposure to water below 20 °C (68 °F) can cause "cold stress syndrome" and death." and >>> "Florida manatees can move freely between fresh water and salt water." Burgersprouts 19:09, 27 December 2022 (UTC) I don't think that's right.
