Common woodlouse
If you were to pick up a rock in the garden, you’d hopefully find a few common woodlouse. These hardy minibeasts have in-built armour and like to hide in warm, moist places like compost heaps.
Compass jellyfish
It's easy to see where the compass jellyfish got its name – its brown markings look just like a compass! They may look beautiful – but they give a nasty sting so keep your distance.
Coot
A familiar black bird of our lakes, ponds and rivers, the coot is widespread; look out for its large and untidy-looking nest on the water in spring. The coot can be distinguished from the similar Moorhen by its white beak and 'shield', and its entirely black body.
Coppery click beetle
The Coppery click beetle is a large, coppery-purple beetle with straw-brown wing cases. It can be found on grassland and farmland, and its larvae are known to feed on roots and damage crops.
Corkwing wrasse
One of the most striking and beautiful reef species found in the UK!
Cormorant
The cormorant is an excellent fisher. It is most easily spotted when it is perched, stretching its wings out in the sun to dry after a dive. The UK holds internationally important wintering numbers of cormorant.
Corn bunting
Like many of our farmland birds, the corn bunting has declined in number in recent years. Spot this streaky brown, thick-billed bird singing from a wire or post - it sounds just like a set of jangling keys!
Cornflower
Once considered a weed of cornfields, the cornflower was nearly wiped out by intensive agricultural practices. Today, it can be found in deliberately seeded areas, and on roadside verges and waste ground.
Cotoneaster
Cotoneaster was introduced to the UK in 1879 from Eastern Asia as an ornamental plant. It is now an invasive non-native species which is taking over valuable habitats including limestone grasslands.
Cow parsley
The umbrella-like clusters of white, frothy flowers of cow parsley are a familiar sight along roadsides, hedgerows and woodland edges.
Cowslip
One of our most familiar spring flowers, the cowslip brightens up ancient meadows and woodlands with its egg-yolk-yellow, nodding blooms.
Crab apple
The Crab apple is familiar as a small tree that produces yellow-green, rounded fruit that is used for making jellies and wines. It can be found in woods and hedges, as well as in cultivated orchards.
