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