Signal crayfish (Pacifastacus leniusculus) moving underwater over stones. Filmed in Surrey, England, UK. The signal crayfish is native to North America, but was introduced to Europe in the 1960s, and to the UK in 1976. It has spread rapidly since then thanks to its greater resistance to crayfish plague, and it is now classified as an invasive species.
