Henry the First, an English King, is said to have died from a surfeit of Eels. He'd been travelling through the Fenlands of East Anglia, during Eel season. That particular Eel includes a visit to the Sargasso Sea in its life cycle, a distance of something like four thousand miles.
The ancestors of Eel that sent Henry the First to his grave, are currently
environmentally challenged. They require the assistance of Eel
enthusiasts, fishermen and bird watchers to maintain their presence as a
species upon our planet. In my own tiny world I am struggling with a surfeit of
Tomato. Which means canning. If I eat one more of them, I'll likely drown.
