Forget Flipper and think more of Jaws – dolphins, the giggling, smiley-faced cutie pies – are in fact psychopathic killers, it seems.
This is the moment two porpoises were attacked and killed a pair of dolphins.
The corpses of the two porpoises washed up soon after, both with horrific injuries to their heads.
Experts at the Scottish Marine Animal Strandings Scheme said that the dolphins were probably just playing.
In a post on its Facebook page, the Scottish Marine Animal Strandings Scheme, said: "Flipper is not as sweet and innocent as he seems.
"Bottlenose dolphins regularly do this, a bit like a cat plays with a mouse.
Maybe think twice before getting that cutesy dolphin tattoo.
