Crossword Genius

They may be shocking swimmers (4)


I believe the answer is:


I believe this is a double definition.

'they may be shocking' is the first definition.
(I've seen this in another clue)

'swimmers' is the second definition.
(eel is a kind of aquatic vertebrate)

(Other definitions for eels that I've seen before include "Else (anag.)" , "They have long bodies and very small fins" , "Smooth fishes" , "Slender fishes" , "Food for Cockney" .)

I've seen this clue in The Globe and Mail.
