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-Finned Blunas are a very social breed of dragon, living in packs of dragons called "pods." Blunas are very curious and playful creatures and several dragons in a pod will often "play" with one other, chasing each other around, tossing seaweed back and forth, and riding ocean swells. They are occasionally seen swimming alongside whales and dolphins.

Bella was the first Bluna in the Storm Crow Clan and for a time the lack of a pod depressed her. She would sit sadly on the beach and throw seaweed into the air in the hope that someone might catch it. No one ever did. However after a time she developed an unlikely friendship with Prometheus, a Magma Dragon, and together they would draw lines in the sand and play noughts and crosses. Bella never won but really didn't mind so long as she was not alone. On days when Prometheus was busy Bella would sometimes paddle out into the deep ocean to meet Thaleia the Deep Sea Dragon, but Thaleia never had time for Bella's playful ways and would remain on the sea bed being mystical. Since the birth of her son Lysander, Bella has been a little happier, but as she says, 'A pod needs more than two!' Bella's favourite colour is orange, her favourite foods are bananas and anchovies and her greatest hope is that there will soon be many more Blunas in the Storm Crow Clan to catch the seaweed with her.
