Found walking along a footpath in Denham Country park 100m from the river Misbourne. Not just able to walk out of water but able to live out of water for up to three months. The Red swamp Crayfish is another invasive to add to the signal crayfish, Mycid shrimp and every other invasive we already have. I posted about it on our local river Frays Facebook page. Others recognised and then posted photos of them walking across a park in Uxbridge and a car boot field. Not sure if signal crayfish or Red Swamp crayfish will dominate but we will soon see.
