Awesome footage of a group of "friendly" manatees examining a transparent canoe in the Weeki Wachee River in Florida, USA.

The footage, filmed on a cold winter's day, shows the animals seemingly getting some entertainment out of the canoe as they try and keep warm in the spring water.

"It was a cold winter day today in south Florida and on cold winter days the manatees gather in many of the springs throughout Florida," the filmer wrote online.

"The See Through Canoe seemed to provide them some entertainment as they stayed warm in the clear spring water."
