Animals found in steamship, possibly (6)
I believe the answer is:
hippos
'animals' is the definition.
The answer is an example.
'in steamship possibly' is the wordplay.
'in' says the answer is hidden in the clue.
'HIPPOS' is hidden in the letters of 'steamship possibly'.
'found' acts as a link.
(Other definitions for hippos that I've seen before include "African natives" , "River horses" .)
