Group of seals (3)
I believe the answer is:
pod
'group of seals' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pod that I've seen before include "A long seed-vessel" , "Seed vessel" , "Seed case of peas" , "Elongated seed case" , "Seed case; whale herd" .)
