This striking duck was introduced to the UK and is now established as a breeding bird in England.

This bumpy shell lives up to its name and lives partly buried in the seabed along the west coast of Great Britain.

Found in compost heaps and under stones in gardens, the flat-backed millipede is a common minibeast. It is an important recycler of nutrients, feeding on decaying matter.

The lesser-black backed gull can be spotted around the coast in summer, with the biggest colony on Walney Island, Cumbria. Look for it over fields, landfill sites and reservoirs during winter.
