One other mystery is what prompted the female snake to give birth this way.

'This female has given birth to sexually produced babies in the past, and only in years that she was housed with males has she produced offspring,' Dr Booth explains.

'It appears that some interaction with a male is required.

'However, why she does not utilise his sperm is at present unknown.'
