A strange piece of footage from China appears to show some kind of large creature emerging from the water of a reservoir to the astonishment of onlookers.

The odd video was filmed in the Chinese city of Jiujiang at the Mount Lu Xihai Resort which is situated next to a Zhelin Reservoir.

In the footage, a dark object can be seen surfacing from the water as witnesses react with what seems to be genuine excitement.

According to those on the scene, the 'creature' appeared to be somewhere between 16 and 19 feet long!

The video has created a firestorm of interest on Chinese social media where it has garnered a whopping 5 million views and counting.

As to what the creature may be, government officials have suggested that it is simply a full-grown sturgeon that managed to escape a nearby fish farm and make it into the reservoir.

While that may seem like somewhat of a fantastic suggestion, it's no less believable than the idea that there is an ancient 'lost' sea creature lurking in the reservoir.
