Baltimore seafood specialty
I believe the answer is:
crab
'baltimore seafood specialty' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for crab that I've seen before include "Nautical nipper" , "Edible crustacean" , "one is a fiddler" , "Fiddler, perhaps" , "Seafood (that can be caught by a rower?)" .)
