Far far away in the Sargasso Sea... Eirian travels nearly 5000km to reach our shores, then swims upstream to live. Twenty years later, she swims all the way back as a huge silver eel! Join Eirian, a European eel, on her life journey as she hitches a ride on the Gulf Stream. Find out why she is now critically endangered and what we can and are doing to help her complete her lifecycle. Become hooked by 'The Eel Question'! Artwork and poetry by textile artist Rachel Harris.
