Are there six for each snake? (5)
I believe the answer is:
viper
'snake?' is the definition.
(I know that viper is a type of snake)
'are there six for each' is the wordplay.
I cannot quite see how this works, but
'six' could be 'vi' (Roman numerals) and 'vi' is found in the answer.
'each' could be 'per' ('per' can mean for each) and 'per' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for viper that I've seen before include "treacherous type" , "poisonous type" , "Deadly-venomous snake" , "A small poisonous snake" , "crawler" .)
