Fair. I think it’s safe to assume that most intelligent species are quite similar to us due to convergent evolution. They likely have at least two limbs for manipulating objects (arms with joints or tentacles), an ability to see objects up close, and some form of hearing.

It might be less likely for their hearing to be as sensitive as ours, or at least the same way as ours. They might have better low frequency hearing to recognize threats if they communicate non verbally.
