Males don't eat during periods of sexual activity. Females stop eating 3-4 weeks before giving birth. Female litter sizes have been recorded as high as 126 young, and litter size is often related to female body size. Tiger snakes from small islands produce fewer, larger young. Baby Tiger snakes when born are 215 - 270 mm in length.
Females produce young at best every second year.
There is no maternal care amongst Tiger snakes. Tiger snakes do not become more aggressive during the breeding season, but a male snake tracking a female may well have his mind on other things and may be more easily surprised or be in an unfamiliar environment. He may consequently be more nervous if disturbed. Found in most habitats throughout Tasmania and on may of the offshore islands. Secure, although some Island populations may decline if offshore activities threaten muttonbird colonies.
