Common starfish
A most familiar seashore inhabitant, the common starfish truly lives up to its name in UK seas and rockpools!
Common sunstar
This large starfish looks just like the sun, with 10-12 arms spreading outwards like rays.
Common tern
During the breeding season, the common tern can be seen around our coasts and also inland at gravel pits, reservoirs and lakes. It nests in noisy colonies and can be spotted plunge-diving for fish.
Common toad
Despite its warts and ancient associations with witches, the common toad is a gardener's friend, sucking up slugs and snails. It is famous for migrating en masse to its breeding ponds.
Common toadflax
Look for common toadflax on waste ground and grassland, and along roadside verges and hedgerows. Its yellow-and-orange flowers are tightly packed on a tall spike and have distinctive 'spurs'.
Common twayblade
An easily overlooked orchid, the Common twayblade is yellow-green and less showy than other UK orchids. Look for it in woodlands and grasslands on chalky soils, in particular.
Common vetch
A scrambling plant, Common vetch has pink flowers. It is a member of the pea family and can be seen on grassland, farmland and waste ground, as well as at the coast.
Common walnut
The Common walnut tree produces a large, brown nut that is familiar to so many of us. It is an introduced species in the UK, and can be seen in towns, gardens and parks.
Common wasp
Wasps are well-known, and unfortunately not very well-loved! But give these black and yellow guys a chance, as they are important pollinators and pest controllers.
Common water-crowfoot
A member of the buttercup family, Common water-crowfoot displays white, buttercup-like flowers with yellow centres. It can form mats in ponds, ditches and streams during spring and summer.
Common water-measurer
Found in ponds and marshes, the fragile look of the Common water-measurer belies its fierce nature. A predator of small insects, it uses the vibrations of the water's surface to locate its prey.
Common whitebeam
Common whitebeam is not a common tree, despite its name. It can be found growing wild in a variety of habitats, but is also planted in towns and gardens. Look for shiny, oval leaves with white undersides.
