In this answer to Are the humans in the Star Wars Galaxy really humans? , it is established that Star Wars

humans are not related to us at all, though they are anatomically identical

And we clearly have encountered dozens of alien animals of various sorts.

Are there any canonically established animals or insects in the Star Wars galaxy which are "anatomically identical" (as far as we can tell) to Earth animals?

Fine print: For the purpose of this question, I'm going to assume that a random background extra probably doesn't count unless there's a substantial reason to believe its appearance was intentional. It would have to be referred to by an Earth name (like "human") and also look identical to an Earth animal, as far as we can reasonably tell. In the case of an offhand mention of an animal without depiction, I would assume it might be an alien analog.


The Ewok Adventure (later released with the subtitle Caravan of Courage) has the caravan traveling with pack horses.

And they are identified by name.

As the second clip shows, there are evidently also ferrets on Endor, but I don't think anyone ever says the word "ferret."

    Playing fast and loose with the words "canonically established", I see...

    @Valorum: Well, you played fast and loose with "based on description they are essentially identical". Oct 25 '19 at 21:35

    Save your complaints for the Christmas special. These movies are more canonical then the 'first three'. If you enjoyed 'those movies' I don't see how you would not like these. They're (one of them at least) actually pretty good and kinda 'dark' for kids movies.

Ducks exist in the (canon) Star Wars universe. They appear to be essentially identical to Earth ducks based on the descriptions

They receive a mention in The Phantom Menace

Captain Panaka If we can't get the shield generator fixed, we'll be sitting ducks.

and again in Star Wars: Ahsoka.

Ahsoka had met the Fardi clan at the shipyards when she’d arrived on the planet. They ran most of the shipping from there, legal and otherwise. Ahsoka would have avoided them entirely, except the younger ones followed her about like ducklings and she hadn’t worked up the bile to discourage them yet.

They also receive a mention in the (formerly canon) A New Hope novelisation

Suddenly the boyish twinkle returned to those piercing eyes along with the old man’s natural humor. “I understand you’re quite a pilot yourself. Piloting and navigation aren’t hereditary, but a number of the things that can combine to make a good small-ship pilot are. Those you may have inherited. Still, even a duck has to be taught to swim.”
“What’s a duck?” Luke asked curiously.

and the Complete Star Wars Encyclopedia (Updated Edition) describes them thusly.

Duck: A common waterfowl native to Naboo and elsewhere.

    Ah, okay. I'm less happy with idiomatic usages like "sitting ducks" since that's an English idiom that would be translated differently even into a different Earth language, and I always assume that all speech in a movie like SW is run through a translation into English that would substitute appropriate English expressions for obscure alien idioms...

    Yes, I agree that "sitting ducks" doesn't bolster the answer. Oct 25 '19 at 17:05

    While, I admit this is the best answer so far, I can't accept it. Even in the original question, I noted "In the case of an offhand mention of an animal without depiction, I would assume it might be an alien analog." Without better evidence that a duck is a duck, we don't know a Star Wars duck is a duck. Here we have three different cases of a narrator or a character using an idiom. What is the evidence that a duck looks like a duck?? You just claimed it out of no where. Oct 25 '19 at 21:34
