An excerpt from the article 13 facts about Komodo dragon

Females lay eggs in September. They can be monogamous and form bonds with chosen individuals, which is an unusual trait among lizards.

Hatches typically consist of 20 eggs and the incubation lasts for seven to eight months. Young spend most of their first years of life on the trees, where they are protected from both predators and older Komodo dragons (young specimens make up for 10 percent of their diet).

They mature within eight to nine years, and their life expectancy is about 30 years in the wild.
