The bodies of six dead Basking sharks have been found in Cornwall, including five that washed up in the space of a week.
According to the BBC, the sharks were found at locations including Gerrans Bay, Coverack Bay, Roseland Bay and the Fal Estuary. It's not known how all of the sharks died, but one of the specimens appeared to have drowned after becoming entangled in buoy ropes.
Environmentalists have suggested to the BBC that the fish may have been killed in fishing nets, but fishermen deny this.
Marine Conservation Society representative Joanna Doyle told the BBC: "Five strandings in the space of one week is highly unusual and very worrying.
"It highlights the importance of reporting strandings and entanglements as soon as possible so that we can determine what is going wrong".
"Basking sharks are protected in the UK, but fishermen should understand that they have not committed an offence if they accidentally entangle a shark.
"We urge all sea users to report shark entanglements as soon as possible."
