The Independent reports on the reality of animals alien to the British ecosystems.
As well as introduced animals, several species of pond plants which have escaped from gardens and parks are also on the list of non-native flora and fauna posing a threat to the country’s rivers and lakes.
The worst offender, according to the Environment Agency, is the killer shrimp which, despite being just 3cm long and, so far, restricted in its range, has a voracious appetite and kills a huge variety of native species such as shrimp and young fish, altering the make-up of habitats it invades.
