My sci-fi story is told from an alien wild animal's perspective. The story is immersive, so the reader directly follows the thoughts and reflexes of the alien. I enjoy writing this way, because the immersion allows me to slowly reveal things the alien thinks are irrelevant (for example, the alien calls humans "outsiders" when interacting with them, so revealing to the reader through implication that they are actually humans makes a cool plot twist).
The problem lies in describing what the animal is. While a short description wouldn't be difficult in a more traditional writing style, since I am directly translating the thoughts of the animal, I am having a hard time coming up with a scenario when the animal would contemplate its own appearance and abilities. For example, people don't often think, "Wow, I am a land-based mammal with two arms, two legs, and a head with eyes and a mouth" in their daily routine (speaking for myself at least).
I've considered leaving the description out and leaving hints throughout the story (example: the creature frequently mentions using its claws, showing the reader it has some kind of claws) and leaving the rest to the reader's imagination. However, for an immersive story, I see this quickly becoming frustrating for the reader, as the events of the plot directly depend on the animal's design and abilities.
Would it be better to add another perspective that offers more description between chapters/segments (Ender's Game does this in a sense) or is there a better way to create a clear image of this creature in the mind of the reader from its own thoughts?
