An unusual fish has been photographed in the Solent.

The Ocean Sunfish, known scientifically as Mola mola, was snapped in Gurnard Bay, off the coast of the Isle of Wight, on Thursday by reader Amy Ferrier.

In the UK, sunfish may be seen between June and September and are most often spotted off south west England.

They can grow to an average length of around 6ft and have no tail, but can grow up to 11ft long and weigh up to 2.5 tonnes.

The species is also harmless to the public.

Its identity was confirmed by marine expert, Tim Ferrero, of the Hampshire and Isle of Wight Wildlife Trust.

He said: "Almost certainly Mola mola, the ocean sunfish, which is not an uncommon summer visitor, as they live in both tropical and temperate waters."

The sunfish may have been following jellyfish, which is one of its primary foods.

"They do eat jellyfish — and they also tend to turn up in our waters in numbers in the summer," added Tim.

"I believe there are also records of sunfish eating eelgrass (a type of seagrass). The north of the Island has some very important, protected meadows."

Amy said: "It's not every day you find a sunfish in The Solent. It was off Gurnard when we sailed past it."

Although there is no definitive evidence to suggest the sunfish sighting is linked to climate change and a rise in sea temperatures, research has shown the warming of the oceans is clear.

As a result, sunfish sightings in British waters may increase in the coming decades.
