This is the rare moment a group of 12 endangered manatees interacted with a canoeist in Florida.<br /><br />The clip, which was filmed off the coast of St Petersburg on June 23rd, shows the marine mammals surrounding the see-through canoe, swimming beneath it and bobbing up to take a closer look.<br /><br />"One of the most unique things about this group of manatees is that they perfectly represented the various shades of light grey to dark brown that a manatees skin can be," said the filmer. <br /><br />"The group of manatees (properly called an aggregation) stopped for about 15 minutes to look the transparent canoe over before going on about their business," he added.<br /><br />Manatees are large, fully aquatic, mostly herbivorous marine mammals sometimes known as sea cows.
