What animals make literally no sound?


there many invertebrates not make sound. however, considered untrue if in different context. crab doesn't make vocal sounds, scuttling across rocks or leaves, can quite noisy. owl makes no noise while flying, can make vocal sounds. depends on context.

i don't want stupid answers turtles or snakes or bunnies (which make hissing or screaming noises semi-rarely) mean besides fish, other animals literally incapable of making noise? don't want answers sponges either because not breathing animals.
