Not only had they spotted a pair of rare Southern Right Whales - one of them was an albino whale.
The completely white calf was closely following its mum as they swam around the shores of the Chile, which is unusual as the creatures are normally found near Argentina hundreds of miles away.

For the surfers enjoying the waves off the coast of Chile, this sighting was a double whammy!
