The barbastelle is a scarce bat that lives in woodland and forages over a wide area. It has a distinctive 'pug-like' appearance because of its upturned nose.

The candlesnuff fungus is very common. It has an erect, stick-like or forked fruiting body with a black base and white, powdery tip. It grows on dead and rotting wood.

The extensive, golden-brown reedbeds that are formed by stands of Common reed are a familiar sight in our wetlands. They provide an important home for many species, including the rare Bittern.

The Natterer's bat can found across the UK, although it is a scarce species. It prefers to forage low down among trees, often taking prey directly from the foliage.

The river lamprey is a primitive, jawless fish, with a round, sucker-mouth which it uses to attach to other fish to feed from them. Adults live in the sea and return to freshwater to spawn.

The grey long-eared bat certainly lives up to its name - its ears are nearly as long as its body! It mainly forages over grassland and meadows, but is very rare in the UK.
