Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.

Dragons don’t communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.

When Water dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

Suichuu Ikijigoku guards the lake where the clan drinks water from. She is jealous of the land and air dragons. She wishes he could live on the land again like when she was a hatchling. Unfortunately she can't. She has to stay in the lake because her weak little legs could not support her own weight on land. If she ever went to go on land she would immediately fall to the ground and be unable to move, crushed by her own weight, stuck there until she died of dehydration. So she lives in the lake. That makes it difficult for her to mate, since she has to convince potential mates to go for a swim with her. Sometimes she succeeds, but more often then not she fails, which makes her one cranky female dragon. Be careful if you go near her lake, she tries to splash anyone she can. And don't fall in. Her preferred method of saving drowners is to bash them with her tail to knock them flying out of the water onto dry ground.
