Deflatersaur

The deflatersaur replaced its ancestor the kelpiesaur. With so many other predators in the area it had to try a new strategy of hunting. It has adapted to take to the air. It shrank to half its ancestors size and evolved light bones for flight. Its swimming membranes were perfect for wings. Its fingers and tail spikes also grew membranes to help it fly. It still swim but is awkward on land. The fins down its back have almost completely disappeared. Its ears have improved so it can listen for struggling prey in the water from miles away. Sadly it cannot hear as well underwater. The deflatersaur's lungs and heart have also improved. This helps it not only hold it breath when submerged but help it with stamina when flying. The deflatersaur are less social than their ancestors and hunt for prey alone. They only meet during mating season. Male and female deflatersaurs will mate for life and will find each other each mating season. Females will tend to the egg while the male gets the female food. Once hatched the male will leave and the female will tend to the chicks until they they learn to fly. After that they are on their own. They build burrows in the mud at the edge of the water where they can escape easily. Durng extreme drought they will hibernate in their burrows until the rain returns. Due to other predators eating so much of the other prey it has exploited prey that it can get to better such as flying prey like the phlyers or prey that needs to come up for air like the finworms.
