This is the terrifying moment a fisherman is chased by a haunting sea creature with glowing eyes.
The unidentifiable creature can be seen repeatedly leaping from the water as it appears to be hunting down the fisherman as he speeds away on a boat.
The 47-second long clip was filmed off the coast of Rio Grande do Sul, Brazil's most southern state, the Daily Star reported.
The anonymous fisherman captioned the footage "wanted to attack me" as he filmed himself desperately trying to escape.
The creature is only just visible in the clip, thanks to two glowing dots which appear to be its eyes.
It jumps out of the water like a dolphin, but appears much more menacing as it almost catches up with the boat.
The creature emerges from the water around 10 times with its eyes glaring at the camera.
Eventually, it is beaten back by the speedboats slipstream.
Some social media users reacted with horror at the clip while others claimed it was "just a seal".
Rafael Santos wrote: “Did you have to change your underwear?
Priscila Lopes said: “What horror! End of days!”
However, others weren’t as impressed and suggested the placing of the caption was intentional to hide the beast's real identity.
Wallace Almeida Barbosa wrote: “It's only a seal lol.”
Gabriel Santiago added: “The guy put the caption right in the middle so we can’t tell what kind of animal it is.”
