Eel - Pond

"Too," I said, "if even a slave's most secret thoughts harbor the least hint of recalcitrance, such an absurdity being inevitably revealed in subtle bodily clues and such, they might be summarily given to leech plants, cast to pond eels, thrown to sleen, such things."

I had also had it confirmed that the snakelike visitants that had so frightened and discomfited me in my tenure in the mostly submerged cage were not water snakes, which tend to favor still water, but eels, in all probability Vosk eels, a form of river eel. Such eels, as other eels, are omnivorous, but, free swimming, are accustomed to feed on small fish and plants. They are unlikely to attack human beings, unlike pool eels, unless their nests are threatened. They are found in fresh water, but return, through the delta of the Vosk, to the salt water of vast, turbulent Thassa to spawn.
