Re: What's that crackling sound I hear at night under the boat?

snapping shrimp (Alpheidae)
https://en.wikipedia.org/wiki/Alpheidae

several species in the drum family have pharyngeal teeth which they use to pulverize molluscs. They also croak:

parrotfish and sheepshead pick at coral and barnacles:
