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 eel is famous for both its slippery nature and its mammoth migration from its freshwater home to the Sargasso Sea where it breeds. It has suffered dramatic declines and is a protected species…
