The latest video posted by YouTube user Lea K, appears to show a large shape with what looks like a fin travelling through the water.
Just last week YouTube user Penn Plate, uploaded a fascinating clip which appeared to show a large creature moving through London’s River Thames, right in front of the auspicious millennium dome.
Hundreds of excited comments have been posted under the videos, with a number of likely (and somewhat unlikely) explanations being given as to what the creature was.
A Russian submarine, a turtle, a basking shark, aliens and even David Cameron escaping in a submarine have all been suggested as alternative explanations.
Nessie was first spotted in Loch Ness in 1933. Has she decided that, after 83 years in one home, she is due a holiday?
