Cornwall Marine Life

Encounter wildlife 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 marine ecosystem, formed by many factors that supports a huge array of wildlife. The foremost major factors are…

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 we have Cape Cornwall that marks the area where three major bodies of water come together. The Irish sea and the English channel, fed by the north sea, slam into the Atlantic. Each hosting its own respective set of nutrients.

Our Long summer days give our photo plankton the opportunity to bloom on a massive scale and our winter storm pumps our waters’ full of oxygen. Then add some of the world’s biggest tides and deep topography to stir the soup pot of biomass.

BOOM! You have conditions needed to support this incredibly diverse ecosystem that really is world class.

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

We are fortunate to encounter a wide array of marine creatures on our trips. 

Different species of dolphins not only come to socialise with us but also forage on the bait fish in dramatic feeding frenzies. We often see various whale species during their migratory passages, taking time to feed in our rich waters, now and then gracing us with their presence. 

The harbour porpoise, one of the smallest marine mammals, is found in large numbers here—a blessing considering their challenging past. The UK is home to 75% of the worlds grey seals. One of the rarest seal species in the world, with our waters serving as a stronghold for them. Additionally, the rare bluefin tuna is making a remarkable comeback from worldwide overfishing. 

Our waters are also home to a large number of the Earth’s shark species, including the basking shark, the second-largest shark, which visits to feed from early spring until the end of summer before disappearing back into the depths of the ocean—its mysterious life yet to be fully understood. Furthermore, sunfish can grow to become the world’s largest bony fish, and these fascinating creatures can reach extraordinary sizes.

The British Isles can proudly claim to be one of the world’s strongholds for pelagic seabirds. Cornwall is home to numerous species that not only forage in our waters but also use our coastline to breed and nest.

The diversity of marine life here is incredible. The wildlife mentioned represents just a fraction of the animals we regularly encounter, merely scratching the surface of what this vibrant ecosystem has to offer.
