Locations losing last English mollusc (5)
I believe the answer is:
venus
'mollusc' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for venus that I've seen before include "Heavenly body" , "One of the planets" , "Brightest planet" , "Roman counterpart of Aphrodite" , "Second nearest planet to the sun" .)
