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 their legs and 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.

BlueDeepWater Dragon lives in a river... quite unusual, as this breed seems to occupy lakes most of all. But he likes it there. Especially that he does not live far from the sea, so when he is bored with the riverside, he takes short trips to the salt water. There he can really enjoy the Deep Blue Water! Unfortunately there is a multitude of jellyfish in the sea and he really hates that. Therefore, eventually he comes back to his favorite spot in the river. There is a huge building nearby and he enjoys watching the people going in and out of it day by day he sometimes wonders what they do inside, because they look really tired when they leave. But, as he cannot live outside the water, this is to remain a mystery
