Coming back from Spain in September, on P&O Britannia, we were very lucky to have a calm crossing of the Bay of Biscay and the opportunity to see dolphins and basking sharks.
For part of the day the ship was sailing due East before turning North to its next destination in Guernsey. This is when I spotted these sharks at the side of the ship.
All these pictures were shot with a Canon 5D Mark III using a 100-400 mm zoom lens at ISO 200
