Amphibian (Earth-2356)

"I heard the admiral amphibian!"

- Han Solo, commenting on Gial Ackbar

Amphibians are species that can breathe both air and water, and are equally at home in either. Examples of sentient amphibious species include the Mon Calamari, the Chagrians, the Gungans, the Nautolans, the Aqualish, the Ishi Tib, and the Karkarodon. The planet of Dagobah is home to a number of quite common amphibian creatures.
