Sea lion pulls off shark impression for paddle boarders

This is the moment a cheeky sea lion tried its best to scare some paddle-boarders by pulling off a fairly convincing shark impression.

The marine mammal swims towards the camera with just its pectoral fin slicing through the water, making it look like the fin of a large shark is approaching.

Soon, though, the family of water sports enthusiasts are giggling with relief as the aquatic impressionist reveals its true identity and jumps up on to the rear of a yacht parked in the harbour.
