Of course they’re similar in many ways; they’re all supplying similar information to the same humanoids, give or take a wrinkly nose and/or other latex foibles ^^’.
Even if they weren’t directly human, if they used similar sensory schema at similar frequencies (highly unlikely as that is in reality) their info/control systems would probably be quite recognizable to us, especially if their manipulative appendage(s) are at all comprehensible.
