A worldwide community photographing and learning about wildlife

The formidable American Signal Crayfish poses a massive threat to native species in rivers, lakes and ponds. Although on the surface everything might appear normal, beneath the waterline the crayfish is waging war on anything that stands in its path. The six-inch-long killing machine has already annihilated the smaller native White Claw crayfish from most of the waterways in the south of England.

Thank you :) it's the perfect mission I was waiting for! I'll keep my eye out for more
Hannah thanks so much for adding a spotting to my mission, you're the first one (apart from me, haha!). This is a good one, the American crayfish is pretty destructive to UK aquatic wildlife. I'll give you the scientific name in an ID suggestion :) Great spot!
