The rare Slavonian grebe is an attractive diving bird with distinctive, golden ear tufts that give rise to its American name - 'horned grebe'.

These gruesome sounding creatures are actually a type of coral! They get their name as they branch out into lobes as they grow - making them look like fingers on a hand.

Look out for the Daubenton's bat foraging over wetlands across the UK at twilight. Its flight is fast and agile as it skims the water's surface for insect-prey.

This smelly, strange looking fungus is also referred to as octopus stinkhorn or octopus fungus. Its eye-catching red tentacles splay out like a starfish.

The green hairstreak is the UK's only green butterfly. Look out for the vibrant, metallic sheen of the undersides of its wings on grassland and moorland, and along woodland rides.

The silvery dace can be seen gathering in large shoals in lowland rivers and streams. It is a member of the carp family and looks very similar to the chub, but is smaller.

Look out for this tiny crab under rocks and boulders on rocky shores - you'll have to look closely though, they're pretty well camouflaged!
