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.

Two headed dragons are a special breed of dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, attacking back and forth. They use their sharp teeth and wings to hunt large animals, and rarely eat plants. It is unknown what would happen if a two headed dragon were to mate with a one headed dragon, since it has never occurred. They only mate within their breed.

Jabba and Wocky are close companions and surprisingly passive for male dragons. They make a good pair when it comes to defending their home though they'd much rather spend their time chasing females and lazing about. Jabba tends to be more reclusive and Wocky and thinks things through more than his other half. Wocky is impulsive but is often balanced by his other head. Together they seem companionable enough though they are prone to their little arguments from time to time which can result in some rather nasty bite marks but nothing fatal. The brothers may knock each other around but they wouldn't kill each other.
