Common sandpiper
The common sandpiper breeds along rivers, and by lakes, reservoirs and lochs in upland Scotland, Northern England and Wales. It can be spotted as a passage migrant at many inland wetlands across the UK.
Common scoter
The common scoter has suffered large declines in the UK, threatening its survival here. Look out for this duck feeding at sea in winter when its numbers are bolstered by migrating birds.
Common sea-lavender
Common sea-lavender can be found around our coasts on mudflats, creek banks and saltmarshes. Despite its name, its not a lavender at all, so doesn’t smell like one.
Common seal
The smaller of our two UK seal species, common seals are also known as harbour seals. Despite being called "Common", they are actually less common than grey seals!
Common sexton beetle
The Common sexton beetle is one of several burying beetle species in the UK. An undertaker of the animal world, it buries dead animals like mice and birds, and feeds and breeds on the corpses.
Common shrew
The diminutive common shrew has a distinctively pointy nose and tiny eyes. It lives life in the fast lane, eating every 2-3 hours to survive, and only living for a year or so. Look out for it in the garden.
Common skate
Despite its name, the "common" skate is not so common anymore. In fact, they are Critically Endangered.
Common sorrel
Common sorrel is a common plant of grasslands, woodland edges, roadside verges and gardens. It is also known as 'sour ducks' because its leaves taste tart.
Common spangle gall wasp
The common spangle gall wasp produces a small, disc-shaped growth, or 'gall', on the undersides of oak leaves. Inside the gall, the larvae of the wasp feed on the host tissues, but cause little damage.
Common spike-rush
Forming mats of straight, bright green stems, Common spike-rush does, indeed, look like lots of tightly clustered 'spikes' near the water's edge of our wetland habitats.
Common spotted-orchid
The common spotted-orchid is the easiest of all our orchids to see: sometimes, so many flowers appear together that they create a pale pink carpet in our woodlands, old quarries, dunes and marshes.
Common squid
The common squid is a weird and wonderful predator found all around our coasts.
