Aiwha
this was a species of flying cetacean native to the planet Naboo, and also found on the world of Kamino. The aiwha was similar in appearance to a thranta. They used a combination of sonar and radar for their communication, and were equally at home swimming in the ocean or flying through the air. A hollow bone structure and large lungs helped the aiwha remain aloft or afloat, and their flat tail was used as a rudder and paddle. Their small legs were not made for walking, and the aiwha preferred to land in the water rather than on land. A vast network of small, almost vascular vessels permeated the flesh of the aiwha, allowing it to adjust its relative mass by pumping water into the vessels to increase mass. When a decrease in mass was needed, the aiwha could expel excess water through a blowhole on their heads. Additionally, the porous tissues of the aiwha's wings allowed for even more precise control of an individual's mass, since water could be absorbed into the tissues when necessary. The aiwhas of Kamino were omnivorous, filtering krill and plankton from the water with their baleen. Many aiwhas were trained by the Gungan and Kaminoan peoples to accept a saddle and harness, and were used as airborne transports. Aiwhas fed on the small fish which inhabited the surface of the ocean, eating primarily daggerts. While it was generally acknowledged that the Naboo aiwhas were indigenous, many xenobiologists believed that the Kaminoan aiwhas were probably transplanted to Kamino and maintained as genetically-bred clones.
