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.

To adhere to the Christian's needs, Clint, a Green dragon, has dug out a large pool in the back of the cave.  It's not like what a human would think of as a pool, with chlorine and whatnot, but more of a large pit filled with water.  This generosity on the Green dragon's part has created a bond between the two, other than the fact that they were the first two males in this particular cave.

Christian has a more distant relationship with his daughter, Studebaker, than with his son, Goodbye, who has been enchanted to remain a hatchling.  He can be gruff at times, and rather non-social, and he tends to avoid hatchlings and young adult dragons because he doesn't like talking to them.
