A picture of a mystery sea creature taken off the coast of Broome has the internet buzzing – because no one seems to know what the HECK it is.

The creature was spotted on the shore of Eco Beach, in WA’s Kimberley region.

Let us know if you have any ideas, but if sharks and crocs are now breeding, not gonna lie, I’m out.
