When to see
January to DecemberAbout
Harbour porpoise can be easily spotted close to shore in shallow water, either alone or in small groups. They are shy and will avoid boats and jet skis. If you do manage to get close enough you may hear their loud “chuff” noise as they come to the surface for air, this gives them their nickname “puffing pig”! Harbour porpoise give birth to a small calf every 1-2 years.How to identify
Look out for a small, triangular dorsal fin breaking the surface. Harbour porpoise are small and stocky, with a dark grey back and lighter underbelly. Their faces are rounded and have no beak.In our area
Scilly's seas abound with wildlife, including a variety of cetacean species including harbour porpoises, common dolphins, minke whales and even bigger species like humpback and fin whales. One of the best ways to see marine mammals is to watch from Scilly's many headlands (like Peninnis or Deep Point on St Mary's, Wingletang on St Agnes, Shipman Head Down on Bryher, Castle Down on Tresco or from the Daymark on St Martin's) or to head out on a WiSE accredited boat operator offshore. Cetaceans don't generally come between the islands, so a trip to the Western Rocks, Eastern Isles or beyond will give you the best opportunities to see them. You can also spot plentiful wildlife on the Scillonian III crossing from Penzance with Isles of Scilly Travel.
Harbour porpoises are very shy compared to their dolphin cousins, so you'll be lucky to see more than a dark fin and a bit of the back breaking the surface once or twice before they disappear. Look beneath diving gannets and big flocks of gulls for a chance to spot fins breaking the surface beneath - both birds and cetaceans will make the most of big shoals of fish or bait balls.
