An autopsy on a Leatherback Turtle found on a Cornish beach has found it's plastic in it's stomach.
The 1.8 metre sea creature was found washed up on Marazion Beach on Sunday (12 August).
Scientists say the plastic did not kill the turtle but say it is found in "almost all" turtles examined and it shows further proof of widespread pollution in our seas.
The University of Exeter team who carried out the examination believe the creature was killed by a boat propeller.
Researchers at the Penryn campus are asking people who use boats to be more careful as more Leatherback Turtles are likely to be in Cornish waters this time of year.
It's thought this particular turtle came all the way from the Caribbean attracted to the number of jellyfish our seas right now.
