A scary jellyfish-eating creature has been spotted in UK waters, as locals have described the animal having a giant swimming head which looks huge, flat and circular.
Several locals have spotted ocean sunfish swimming in the inlet of Plymouth Sounds on Friday, after a hoard were spotted in the sea last week.
A local who was out fishing for mackerel shared pictures of the strange jellyfish-eating creature.
The images depict the sunfish almost at the surface of the water.
As temperatures rise and more jellyfish take over the waters, it is said that sunfish are more likely to be spotted by locals who are going for a swim or take part in any water activities.
Last week swimmers across Plymouth saw jellyfish in Millbay Docks and Plymouth Sound.
According to Wildlife Trusts website, the ocean sunfish is the second largest bony fish on the planet and visits UK seas during the summer months to feast on jellyfish.
Sunfish are often spotted resting on their sides at the surface of the sea, supposedly basking in the sunshine - which is where the English name of sunfish comes from.
Wildlife Trusts say: "The fin at the surface can easily be mistaken for a shark, but once up close they are unmistakable.
"Sunfish feed on jellyfish and salps (as such they are known as jellivores!), as well as a wide range of other animals.
"Smaller sunfish have the most varied diet - when they're under one metre in length, around half of their diet is jellyfish and the other half is a mix of species that live on the seafloor, like crustaceans, molluscs, and even some fish."
How to identify a sunfish
The Wildlife Trusts website states: "A giant grey fish that looks a lot like a swimming head. They are round, reasonably flat and have no noticeably tail - simply a frill of skin (the clavus).
"They have 2 long fins - the dorsal fin and the anal fin which they use like paddles to steer and wings to swim. These fins can sometimes be seen flapping at the surface."
