Bursas were large predators in the swamps and savannas of Naboo. They killed pikobises, motts, falumpasets, ikopies (similar to Earth's okapies) and many other Naboo species. They sometimes competed with Tusk Cats (similar to Earth's extinct Thylascomilus) as they preyed on the same grazing animals. The bursas were also kept by royalties in different parts of Naboo. The favourite prey of the Bursa was the Shaak which species meat were quite juicy and slow moving. Bursas also preyed upon the Gungans. The only natural enemy of the Bursa is other Bursas, Tusk Cats and bigger herbivorous creatures.
