Creature/Ecology

The following is an analysis on how creatures behave in the story of Duel Masters.

Lifespan
Creature lifespan tends to vary between individuals, some such as Living Dead from the ancient Darkness Civilization tend to be very short in lifespan, spanning their life in less than a few months to years only to be resurrected again, while others such as Aquan, Gyuujinmaru, Legendary Identity and Prin had been living on for tens of thousands of years with their appearance barely changing. Others such as Dragonoids and Humans share the same lifespan as regular earth Humans.

Society Structure
Most creatures do have a society structure, most notably the Civilizations shared between the creatures themselves. Early creatures tend to live in millitary advanced societies such as in the case of the Ancient Light Civilization, and the Ancient Fire Civilization, or primitive tribal societies such as Nature Civilization. Later on creatures that base their society on advanced Monarchy existed, in the case of the Aliens and the Dragon Saga Dragons. Others such as Oracles and Outrages, run earth human-like advanced societies that are based on a various value. Various races, such as Human Baku are known to have human world-like structures such as Education and Marriage.
