On my office floor in a cardboard box is nearly half a metre of fresh eel, found dead near to our fish pond. The mystery of our guests’ presence here has caused quite a stir today- both staff and visitors peering down in curiosity at the leathery corpse. Its dull grey appearance catching the light is anything but ordinary as we dwell on how it would twist its way through the cold water, occasionally moving over land in wet weather- preferring to migrate on moonless stormy nights.
Eels had factored very little on my biodiversity radar until today when I decided it would be worth doing some research into their biology and habitat. It didn’t take long until I had pinned this particular individual to a species – ‘Anguilla anguilla’ or the European common eel. Don’t be fooled; this fellow is anything but common, especially gnawed in half and discarded next to a lake in mid-Wales. In fact these eels are now in steady decline and appear as critically endangered on the IUCN Red List, the reasons for which remain unclear- although it is speculated that damage to habitat, overfishing and global warming might be contributing factors.
