Little lizard (5)
I believe the answer is:
gecko
'little lizard' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for gecko that I've seen before include "Thick-bodied lizard" , "Small tropical lizard" , "Cold-blooded type" , "Small lizard with adhesive foot-pads" , "Lizard with adhesive toes" .)
