Astronaut I like keeps marine molluscs (7)

I believe the answer is:

nautili

'marine molluscs' is the definition.

'astronaut i like keeps' is the wordplay.
'keeps' indicates the answer is hidden within the clue.
'NAUTILI' is hidden within 'astronaut i like'.

(Other definitions for nautili that I've seen before include "creatures in the sea" , "marine life" , "Cephalopod molluscs" .)

I've seen this clue in The Independent.
