 Ubirr's proximity to the East Alligator River and Nadab floodplains means that food would have been abundant and this is reflected in much of the rock art here.Animals depicted in the main gallery include [[barramundi]], [[catfish]], [[Mullet (fish)|mullet]], [[goanna]], [[Chelodina|snake-necked turtle]], [[pig-nosed turtle]], [[rock-haunting ringtail possum]], and [[wallaby]] and [[thylacine]] ([[Tasmanian tiger]]).There are also images of the [[Rainbow Serpent]] said to have created much of the landscape as well as mischievous Mimi spirits and the story of the Namarrgarn Sisters.
