The happy little family was spotted at Florida's Homosassa Springs -- where swimming and snorkeling with the endangered, enormous, vegetarian creatures is legal (though advocacy group Save the Manatees advises obeying anti-harassment guidelines).
The person who took this video July 11 and posted it to Facebook is Gene Parker, who has a job title that also makes us swoon: manatee tour guide.
Parker said in his Facebook post that he's "been doing this for almost 15 years everyday and never seen a new born twins in the wild."
“It was almost like she was showing off her newborns," Parker told Bay News 9 of the twins' mother.
