Creepy crawly creature, but no insect (7)
I believe the answer is:
reptile
This could be a double definition.
'creepy crawly creature' is the first definition.
'reptile' can be an answer for 'creature' (reptile is a kind of creature). I am not certain of the 'creepy crawly' bit.
'no insect' is the second definition.
'reptile' can be an answer for 'insect' (thesaurus). I'm unsure of the 'no' bit.
'but' acts as a link.
Can you help me to learn more?
(Other definitions for reptile that I've seen before include "Cold-blooded creature" , "Unpleasant character" , "Malignant creature" , "Eg, snake, lizard, etc" , "Cold-blooded vertebrate" .)
