- average length of 2.6 m and an average weight of 40-70 kg.
- harp, curved claws and around 60 curved, serrated teeth with 4-5 replacement teeth at each position

Courtship and Mating
- occurs between May and August
- sexual maturity for both males and females is 5-7 years
- dominant males fight by rising up on hind legs, using theirs tails as support, and grabbing at the other male with their fore legs
- courtship is very brief
- females often attack males during the early phases of courtship
- sex ratio in wild is 3 males:1 female
- females lay an average of 18 eggs in a burrow in the ground over several days in September
- females clutch once a year
- eggs have soft, leathery shell and incubate for 2.5-8 months
- hatchlings appear in April or May and weigh about 80 g
- no evidence of parental care
- not many young survive to adulthood, and they often fall victim to many predators
- if they survive until 5 years old, they can reach up to 2.5 m long and weigh 25 kg
- they live up to 25 years in captivity; Auffenberg estimates a lifespan of 50 years in the wild
- offspring resulting from parthenogenesis are all male
- use the ZW sex-determination system in which males are ZZ and females are ZW
- the female provides her progeny with a haploid set of chromosomes (and only one sex chromosome: Z or W)
- the haploid set is replicated and eggs that receive a Z chromosome become ZZ (male) and develop. Eggs that receive W become WW and fail to develop
