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 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.
