Mail on Sunday 36A small soft-bodied crustaceans living in the gill cavities of certain shellfish O?S?E?/??A?S I’ve seen this answered as Oyster Grass but I’m thinking it’s Oyster Crabs as in crustaceans any help would be much appreciated,thanks in anticipation.
I'm with LiK on this one.
The 'only' definition I can find for oyster grass is 'kelp, sea lettuce', whereas the link provided contains almost the same wording as the clue.
I appreciate that but the reference to lives in the gills of Oysters/Clams (shellfish)is what is mentioned in the clue,I’ve looked up Oyster Grass and couldn’t find reference to this
