At 20:10 last night on the way out from Amsterdam, a Thresher shark breached twice off the starboard bow of the ship. It was absolutely amazing and luckily 6 passengers were there to witness it. They are very easy to identify as they have very long pectoral fins and whiplike tail. Unfortunately the appearance was so brief that I wasn’t able to get a photograph.
The Common Thresher Shark is found globally, even in cold waters. This species is especially vulnerable to fisheries exploitation because it prefers to live close to the surface (within 200 metres or so). Thresher sharks are solitary creatures which keep to themselves and their numbers have decline rapidly in recent years. A really great sight from the King Seaways!
