A couple fishing just off the coast of Sanibel Island, Fla., claims to have seen some sort of sea monster in 2013.
They posted their video on LiveLeak (explicit language warning), and stated: "we saw what looked like a bus speeding through the water. At first we thought we were watching manatee swimming which we see all the time but this animal was moving very fast and looked to be attacking something."
The couple says that the creature may have been a 20-foot snake, but its head resembles a sea otter.
Check out the video below and tell us what you think they saw.
