Not vocalizations, but each species has unique dentition that makes them easy to identify due to their constantly gnashing teeth.

Now I really don't feel better!😨

well, atleast their teeth are in the normal place for teeth to be, and they're being used for normal teeth things. mouth-teeth gnashing is a fairly standard, very earthy, non-alien thing that perhaps you could think of as a soft reminder that spiders are just tiny animals. crabs on the other hand

I appreciate hearing your perspective 🕷️🕸️
