Man picked up She's Electric, maybe? (3)
I believe the answer is:
eel
'man' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for eel that I've seen before include "Proverbially slippery fish" , "Wriggly fish" , "Slippery type" , "Evasive type" , "Serpentine fish" .)
