The giant fish in the middle of the desert makes 0 sense to me. If this is a supposed remnant of ancient Tatooine’s oceans it’s absurd that it would remain intact as a skeleton , let alone fresh meat!
I would assume it is somekind of a flying creature that actually lives in space. Maybe it died near Tatooine’s orbit and its corpse crashed in the desert?
Digression: In Star Trek that kind of thing - creatures living in space - is not uncommon.
