Spotting

Description:

This little guy I only spotted because he moved. He is really well camouflaged. I couldn't even tell if he had 6 or 8 legs. So spider or crab?! He also seemed to have small antenna sticking out. The body was quite uneven so looked more like he has placed vegetation on himself rather than that is his natural body shape. A bit like a decorator crab, but on land...??
