My Hermit crabs are incredibly noisy for no reason

[HermoCrabbo]

I got 3 PPs a couple weeks ago from a store that didn't nearly have the right conditions for them, and so I've been trying to graduate them into perfect conditions to prevent extreme PPS. They essentially have everything except multiple shells (which should be coming soon), and they seem pretty active and happy. The only problem is the largest (and most friendly) one has been chirping loudly at night all the time for seemingly no reason. Everytime I got and check, there are no issues but I'm still worried something is going wrong. What's happening? What should I do?

You *might* just have crabbies that like to talk.

Sometimes they can just be more vocal than others. I wouldnt worry too much

Interestingly, there seem to (probably) be three different methods of noise production in crabs.

One has been presumed by sciency-folk and assorted crabbers over the years as the bumpy bits on their claws (a raspy bit on their chelipeds) that they rub, sort of lIke crickets stridulating. Not all land Hermie species have this, but PPs do.

The second has been reported by crabbers & is a mouth-bits noise. (I don't think I've heard this, but I'd like to).


The third involes the actual shell... and many new crabs come in older, crab-modified shells, where the center of the snail shell (which has a piller called a collumela), has become worn down by the crab (or many crabs) over time.

Sciency dudes discovered (indos? Was it indos? I'm too lazy to look it up) some crabs
using the hard bits at the very tip of their abdomens (called the telson) to rasp the columela, creating a chirping noise.

I think I have heard this... I had a PP that made CRAZY loud cricket noises every night until she changed into a new, un-crab-modified shell... then barely a peep from her ever again.

Oh that is so interesting!!! The only sound I've ever heard my pps make is a clicky noise and a weird noise that sorta sounds like a bendy straw.
