The last thing you’d expect this extraordinary creature to be is a fish!

A recent colonist to south east England, the metallic-green willow emerald damselfly spends much of its time in the willow and alder trees that overhang ponds, lakes and canals.

A pretty and distinctive little waterbird, the mandarin duck was introduced from the Far East as its name suggests. Oddly for a duck, it nests in trees, sometimes high above the water.

The thresher shark is a migratory species and passes through UK waters in the summer months. If you’re lucky, you might see this magnificent shark jump high out of the water in to the air.

Look out for a common lizard basking in the warm sun as you wander around heathlands, moorlands and grasslands. You might even be lucky enough to spot one in your garden, too!

If you happen to be near rocky places such as sea cliffs, shingle coastlines or even gravel paths during the summer months you will most likely come across sea campion.

Largely confined to the north of the UK, the rare pine marten is mostly nocturnal and very hard to spot. Reintroductions are helping it make a comeback.
