Their skeletal structure is extremely flexible, as it is made of cartilaginous material rather than hard bone. This makes their faces rather expressive, and makes their bodies more resistant to damage. Gungans have strong leg muscles for swimming, and are aided by their long fin-like ears. Gungan arms end in four-fingered hands, and their feet have three stubby toes each. There isn't much visible physical difference between female and male Gungans.
Females tend to be slightly smaller, with sleeker faces.
They often tie their long ears back. The long Gungan face has a tough yet flexible bill for burrowing and rooting out food. They have long muscular tongues with which they scoop mollusks and lesser amphibians from the Naboo swamps. Their teeth are large and blunt, capable of cracking through shellfish. Their large nostrils completely seal for underwater travel.
