Sand eels are a hugely important part of our marine ecosystem. In fact, the fledgling success of our breeding seabirds entirely depends on them.

The stinging nettle is a familiar and common plant, often firmly rooted in our memories after our first, hands-on experience - a prickling irritation that's not forgotten easily!

The wild rock dove is the ancestor to what is probably our most familiar bird - the feral pigeon, which is often found in large numbers in our towns and cities.

Bell heather is our most familiar heather. In summer, it carpets our heaths, woods and coasts with purple-pink flowers that attract all kinds of nectar-loving insects.

It's easy to see where this stunning bivalve got its name from - the bright orange tentacles emerging from the shell really do look like flames!

The tiny, grey-brown house mouse is one of our most successful mammals. It thrives around buildings but is less likely to be found in our houses these days due to better construction.

Yarrow can be found in many grasslands, from lawns to meadows, its flat-topped clusters of flower heads appearing from June. Cultivated varieties are garden favourites.
