Four identification tools are accessible from the drop-down list below. The first is our well-known multi-access key tailored specifically for UK earthworms. The second is also a multi-access key, but it emphasises different features - zoomable photographs are also accessible from this key. The third - the Circle Pack Key - allows you to explore the distribution of morphological features across different earthworm genera. The fourth - a side by side comparison tool - allows you to directly compare features from two ore more different species of earthworms and also to compare photographs where they exist.
Please note that these tools are designed for use on laptop or PC computers and will not work as well on touchscreen devices.
