Hardbacks from Sweden in accurate translation (9)
I believe the answer is:
crustacea
'hardbacks' is the definition.
(animals with hard backs)
'sweden in accurate translation' is the wordplay.
'sweden' becomes 's'.
'in' indicates putting letters inside.
'translation' is an anagram indicator.
'accurate' is an anagram of 'crutacea'.
's' inserted within 'crutacea' is 'CRUSTACEA'.
'from' is the link.
(Other definitions for crustacea that I've seen before include "Shelled group" , "crabby group?" , "class of seafood" , "Collection of hardbacks" , "shellfish" .)
