Features of the cells found in sandbar sharks
I believe the answer is:
bars
'features of the cells' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'in sandbar sharks' is the wordplay.
'in' indicates the answer is hidden within the clue.
'BARS' can be found hidden inside 'sandbar sharks'.
'found' is the link.
Can you help me to learn more?
(Other definitions for bars that I've seen before include "Watering holes - units in musical scores" , "Obstacles" , "Prohibits; sandbanks" , "Excludes; sandbanks" , "Prohibits; pubs" .)
