BEHAVIOUR
LIVING TOGETHER: Many species, spend their entire lives (or part of it) in close relationships with other species. For example, killer dolphins often hunt and will sometimes mate with shark dolphins. Dilophodragons will flock with red headed dragons. Hybrids are sterile
FIRE BREATHERS AND WATER SPITERS: Those dragons have an extra lung behind the heart called "mini lung". It is small in size when empty but can expand. During digestion, a gas is produced in the stomach. This gas is stored in the mini lung. When the dragon wants to breathe fire, it actually breathes out this gas that ignites when it contacts air. The water-spitters are amphibians and drink a lot of water. During digestion, some of that water is absorbed to maintain the body. The rest is stored in the mini lung where it boils. When the dragon spits it, it comes out hot in great pressure
The mini lung
REPRODUCTION: The dragon's reproductive system is rather amazing. They look like reptiles yet they are warm blooded (they are actually related to birds). The gestation period lasts 10 months. The animal male's penis are hidden away (like lizards). The anthro's genitals though look like human's. Female anthros have breasts from where they suckle their young. Males don't have nipples. Anthros have both the ability to lay eggs or give birth to live young. They just keep the egg inside their body until it hatches, and then give birth to the hatchling. The first birth though is recommended to be egg laying. This is possible with a wild plant that wild pregnant dragons eat when the time to lay their eggs have come and yet there is danger, or the food is rare. This plant stops the birth progress thus keeping the egg inside the female's body. (thanks to Eric for the help) Female anthros have their period one week every month.
Closed eyes. Maybe purring: relaxed and trusting
Arched back (if feathered:) standing up, (if wars) drawn flat back: Afraid, defensive
