“The Komodo dragon, as befits any creature evoking a mythological beast, has many names. It is also the Komodo monitor, being a member of the monitor lizard family, Varanidae, which today has one genus, Varanus. Residents of the island of Komodo call it the ora. Among some on Komodo and the islands of Rinca and Flores, it is buaya darat (land crocodile), a name that is descriptive but inaccurate; monitors are not crocodilians. Others call it biawak raksasa (giant monitor), which is quite correct; it ranks as the largest of the monitor lizards, a necessary logical consequence of its standing as the largest lizard of any kind now living on the earth…. Within the scientific community, the dragon is Varanus komodoensis. And most everyone calls it simply the Komodo.” Claudio CiofiThe giant lizard Komodo dragon
The Komodo dragon is an ancient species whose ancestors date back over 100 million years. The varanid genus originated between 25 and 40 million years ago in Asia. The Komodo descended from this species and evolved to its present form over four million years ago.
The Komodo is long lived (as are most of the larger reptilian species) with an estimated life expectancy of over 50 years in the wild. In keeping with its longevity, the Komodo matures late in life, becoming sexually viable at five to seven years, and achieving maximum body density in fifteen years. Komodos are sexually dimorphous, which means males are bigger than females. The largest recorded specimen was 3.13 meters in length and was undoubtedly a male. Females rarely exceed 2.5 meters in length. What is perhaps more important, is that the characteristic bulk is achieved by older dominant males in clearly delineated territorial areas. As an adult Komodo can consume up to 80% of its body weight in one gorging, weight is a highly variable factor, and is largely dependent on the most recent feeding. A typical weight for an adult Komodo in the wild is 70 kilograms.
