Warty amphibians (5)
I believe the answer is:
toads
'warty amphibians' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for toads that I've seen before include "Loathsome types" , "Froglike amphibians" , "Leaping amphibians" , "Frog-like land animals" , "Tailless amphibians" .)
