  • Common Toad Bufo bufo Length 5-9cm A widespread toad; the only common species in Britain. Skin is covered in toxin-containing warts. Spawn is laid in double-rowed spawn strings. Gait consists of short hops. Adult is olive-brown to greenish buff (hue is influenced by ambient light). Has red iris and webbed hind feet. Female is larger than male. Juvenile recalls a tiny, large-headed adult. Courting male utters croaking calls in spring. More terrestrial than most other amphibians and adults spend much of their lives on land:  woodland, scrub, grassland and moors are favoured. Must return to water to breed and most are found within 2km or so of suitable ponds. Not deterred by fish: tadpole’ toxic skin acts as deterrent to predation. Observation tips Courting is easy to watch in suitable ponds in spring (February-March are typical months). Sometimes found hibernating under logs in winter.

  • Salmon - Salmo salar Length to 150cm. Large and distinctive fish. Found in open seas for much of life, but migrates into freshwater to spawn. Adult has streamlined, powerfully muscular body. At sea, silver-grey above, silvery-white below, with dark spots on back and flanks; spawning individuals become duller and more yellow. Widespread and locally, and seasonally, fairly common, least so in E and SE.

  • Common Frog Rana temporaria Length 6-10cm Widespread amphibian. Adult male has smooth, moist skin. Usually olive-yellow or greyish brown with variable dark blotching and spots. Darker red animals occur in uplands. Eye has yellow iris with dark, oval pupil. Dark mask runs from eye to eardrum. Underparts are greyish white with faint darker marbling. Hind feet have five webbed toes. In breeding season, acquires bluish throat and swollen nuptial pads on innermost digit of front feet, used for gripping female when mating. Adult female is similar but larger with white granulations on the flanks. Juvenile, when newly metamorphosed resembles miniature adult but with large head. Male utters low-pitched croaking calls when courting. Found in a wide range of habitats if still water is present for breeding. Easy to see in early spring when courting.

  • Midwife Toad Alytes obstetricans Length 4-5cm Short-legged, squat amphibian. Unusually for amphibians, mating takes place on land and the male carries the eggs until it is time for the tadpoles to hatch, at which point he seeks out water. A native of mainland Europe; several long-established colonies are present in Britain.

  • Salmon Salmo salar Length to 150cm<br />
Large and distinctive fish. Found in open seas for much of life, but migrates into freshwater to spawn. Adult has streamlined, powerfully muscular body. At sea, silver-grey above, silvery-white below, with dark spots on back and flanks; spawning individuals become duller and more yellow. Widespread and locally, and seasonally, fairly common, least so in E and SE.

  • River Lamprey Lampetra fluviatilis Length to 30cm<br />
A migratory species, adults moving upstream from the sea in winter and spring to spawn on gravel beds in rivers. After spawning, the adults die and the larvae that hatch from the eggs live for several years buried in river silt; following metamorphosis to the adult stage, they move to sea until maturity and the cycle is then repeated. Adult River Lampreys attach to other fish using the sucker and feed on blood; they also feed on carrion.

  • Brown Trout Salmo trutta Length 30-50cm <br />
This familiar sport fish is known in two forms: the Brown Trout, which spends its entire life in freshwater; and the so-called Sea Trout, which only ventures up rivers to breed. Both forms spawn in gravel beds in shallow water. An adult Brown Trout has an orange-brown body adorned with red and black spots; a Sea Trout is pale and silvery with a few dark spots. Brown Trout are widespread and often common in fast-flowing unpolluted rivers and streams. Sea Trout are scarce and declining, found mainly in the W and NW of Britain.

  • Brook Lamprey Lampetra planeri (L 15cm) Elongated fish, resident in unpolluted streams and rivers. It spends most of its 3-5 year lifespan as a larva living buried in silt; here it filters organic matter. Following metamorphosis, adults are sometimes seen spawning in Apilr-May in shallow gravel beds; the sucker is used to move stones to create an egg-laying site. Adults die after spawning.

  • Common Eel Anguilla anguilla Length 0.5-1m<br />
The Common Eel spawns in the Sargasso Sea, on the other side of the Atlantic Ocean, and young larvae drift across in the Gulf Stream for 3 years or so. On reaching our shores, so-called elvers swim up rivers and after several years become familiar yellow-bodied, snake-like Eels; on reaching maturity they turn silvery, migrate down the sea and are presumed to attempt their oceanic journey in reverse. During the time in Britain, Common Eels live among silt and debris at the bottom of ponds, rivers and canals.
