What is the snapping sound in mangroves?

The snapping sound in mangroves is primarily produced by snapping shrimp, also known as pistol shrimp. These small crustaceans create a loud snapping noise by rapidly closing their claw, which generates a cavitation bubble that collapses with a sharp sound. This behavior is used for communication and to establish territory. In mangrove ecosystems, the sounds contribute to the overall acoustic environment, highlighting the biodiversity of these habitats.
