Well tanned women, fit and robust, trap second shark (6,6)

'shark' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'well tanned women fit and robust trap second' is the wordplay.
I cannot quite understand how this works, but
'well' could be 'hale' (I've seen this in another clue) and 'hale' is found within the answer.
'tanned' could be 'bronze' (I've seen this in another clue) and 'bronze' is found within the answer.
'women' could be 'w' and 'w' is found within the answer.
'trap second' could be 'r' (2nd letter of 'trap') and 'r' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
