Soil-dwelling invertebrate (9)
I believe the answer is:
earthworm
'soil-dwelling invertebrate' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for earthworm that I've seen before include "Soil-dwelling invertebrate" , "Creepy-crawly" , "that's throwing up on the lawn" , "Tunneller" , "Garden burrower" .)
