Amphibians seen around during most Februaries (4)
I believe the answer is:
efts
'amphibians' is the definition.
(eft is a kind of amphibian)
'around during most februaries' is the wordplay.
'around' says the letters should be written in reverse.
'during' indicates the answer is hidden within the clue.
'stfe' can be found hidden inside 'most februaries'.
'stfe' written backwards gives 'EFTS'.
'seen' is the link.
(Other definitions for efts that I've seen before include "Kind of newts" , "Baby newts" , "Old lizards" , "Amphibians" .)
