Caught with such as skate and another aquatic creature, lobster (8)
I believe the answer is:
crayfish
'lobster' is the definition.
(I know that crayfish is a type of lobster)
'caught with such as skate and another aquatic creature' is the wordplay.
I cannot really see how this works, but
'caught' could be 'c' (cricket abbreviation) and 'c' is present in the answer.
'skate' could be 'ray' (I've seen this in another clue) and 'ray' is found within the answer.
'creature' could be 'fish' (fish is a kind of animal) and 'fish' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for crayfish that I've seen before include "Lobster-like crustacean" , "Edible crustacean" , "Catch" , "little nipper" , "Lobster-like creature" .)
