I'm a little stuck... Click here to teach me more about this clue!

'shrimps etc' is the definition.
I can't tell whether this definition defines the answer.

'saucer cat licked' is the wordplay.
'licked' indicates an anagram (lick can mean to beat or hit).
'saucer'+'cat'='saucercat'
'saucercat' anagrammed gives 'CRUSTACEA'.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for crustacea that I've seen before include "crabby group?" , "Shelled group" , "Prawns and lobster" , "shellfish" , "Collection of hardbacks" .)

I've seen this clue in The Guardian.
