Shells erode farm view from the sound (7)
I believe the answer is:
nautili
'shells' is the definition.
The answer and definition can be both animals as well as being plural nouns.
Maybe they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nautili that I've seen before include "marine life" , "creatures in the sea" , "Cephalopod molluscs" .)
