Scott Waring of UFO Sighting Daily thinks it could be a sea monster.
“This looks like The Kraken. I used Google ruler and it says this is 30 meters (100 feet) from head to end, but the end looks just like the mid area of a giant squid which means it could be 60+ meters long with tentacles. That sounds like a Kraken to me," he wrote.
A kraken is a mythical tenticled monster, known in tales of the sea for drowning people and ships.
The picture was taken near Deception Island in the South Shetlands and appears to show a `fin`.
Some think it could be the Loch Ness Monster, but others think it could be an underwater UFO.
Some have a more rational explanation for the strange object.
We share our planet with some huge sea creatures - but not krakens - so it is probably more plausible that this image is of a blue whale or a similarly large animal.
This won`t stop conspiracy theorists saying it is definitely a UFO full of aliens coming to eat us all.
Because we have better quality photography equipment, and don`t have to rely on word-of-mouth from scared sailors, sightings of krakens and other sea monsters have gone down.
However, grainy satellite images often still show images which the more paranoid of minds can mistake for ships or monsters from outer space.
Do you think we have found a kraken? See for yourself.
