Basking Sharks

The Isle of Man is a global hotspot for basking sharks

Basking sharks are the second largest fish in the world and, although they can grow to over 10 metres long and weigh as much as 7 tonnes, they are gentle giants.  They feed only on tiny animal plankton which they sieve out of the water by swimming through it with their vast mouths wide open.

Between May and August, the Manx coastline welcomes this endangered species to feed on plankton blooms and possibly to mate and give birth in our waters.

Catching a glimpse

Your best chance of spotting a basking shark is on a flat calm, sunny day – look out for their dark dorsal fins, slicing through the water.

They can easily be seen from the shore, especially from spots like Peel Castle (see photo, right), Niarbyl, Port Erin and the Sound.

For an even closer view, you can also take a boat trip; we recommend you choose an experienced skipper who knows how to safely and responsibly drive around marine wildlife.
