Something less like a lobster, more like a shrimp (5)
I believe the answer is:
prawn
'shrimp' is the definition.
(I know that shrimp can be written as prawn)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for prawn that I've seen before include "Small, edible crustacean" , "basis for cocktail" , "Bit of seafood" , "Large shrimp" , "Marine crustacean" .)
