Medico bravely hides snake (5)
I believe the answer is:
cobra
'snake' is the definition.
(I know that cobra is a type of elapid)
'medico bravely hides' is the wordplay.
'hides' indicates the answer is hidden within the clue.
'COBRA' is hidden in the letters of 'medico bravely'.
(Other definitions for cobra that I've seen before include "government emergency committee?" , "Highly venomous hooded reptile" , "Poisoner" , "Type of snake" , "Sinuous creature" .)
