Watch this video of hundreds of manatees lounging at Three Sisters Springs

In the meantime, Three Sisters Springs will be a safe, and warm haven, for the manatees.

A new video shows hundreds of manatees seeking shelter in Florida’s Three Sisters Springs.

Ivan Vicente, a visitor services specialist with the Fish and Wildlife Service told CNN that the mammals sleep “for over a whole day”.

Manatees can’t tolerate water less than 68 degrees for a prolonged period of time.

The area was reopened Tuesday but is expected to close to water access when the high tide comes again, according to Time.

One of the main reasons that this refuge is so important is because cold water stress can be fatal for manatees, and even those that are at the Three Sisters Springs can lose a considerable amount of weight.

Crystal River National Wildlife Refuge Complex posted on Facebook Monday that the large concentration of manatees would cause the spring to close, as not to disturb the animals.

Three Sisters Springs is a natural body of warm water that provides refuge for the endangered Florida manatee.

We knew it was Florida the minute we heard ‘300 manatees close a national landmark, ‘ but we didn’t know the story was going to be this sweet.
