With its horns, long white body and slithery form, it looks like a mythical beast

But this four-metre long horned creature is only too real - as the stench from its decomposing flesh proved.

The mysterious sea creature was washed ashore in Villaricos, Spain - and tests are being done on the carcass to determine what it is.

An unfortunate swimmer stumbled across the head before coming across the rest of the body, the Huffington Post reported.
