Cornwall Marine Life

Encounter wild sealife in their natural environment

Cornwall has an extremely rich ecosystem that supports a huge array of wildlife.

The ocean is not a zoo and we can’t guarantee what you will see. However, we can guarantee you will see a lot! As a non-invasive boat trip, all the wildlife is undisturbed in their natural environment. This approach gives an unforgettable experience that you can truly feel privileged to encounter.

About Cornwall's Ecosystem

Cornwall has an extremely rich ecosystem that supports a huge array of wildlife. The ocean conveyor brings the cold waters from the north and the warmer waters carried from the Caribbean Sea together, right off our coast. This change in water temperature creates columns of extremely nutrient-rich waters. Then add some of the world’s biggest tides, stirring the soup pot of biomass. And boom! You have conditions needed to support this incredibly diverse ecosystem.

38% of the globally endangered grey seals live in UK waters.

The peregrine falcon is the fastest animal on earth, reaching speeds of 240mph!

The basting shark is the second biggest fish in the world way up to 5.5 Tons.

Cornwall's waters - a haven for wildlife

All kinds of dolphins, taking time out of their day to come and socialise with us . Different whales species on their passing migrations, gracing us with their presence. We have the harbour porpoise, one of the smallest Marine mammals. The rare bluefin tuna that is making an incredible comeback from worldwide overfishing. The UK waters hold a large number of the earth’s shark species. The second biggest shark, being the basking shark, comes to feed in our waters from early spring to the end of our summer. They then disappear once again to its mysterious life, that science is yet to track. Then there are sunfish. As the world’s biggest bony fish, these bizarre creatures can grow to an extraordinary size.
