Is the pistol shrimp useful or harmful to humans?

The pistol shrimp is generally not harmful to humans; in fact, it plays a beneficial role in marine ecosystems by aerating the seabed and creating habitats for other species. Its powerful claw can produce a loud snapping sound that stuns prey, but it poses no direct threat to humans. However, in some cases, its noise can interfere with underwater communication for marine activities. Overall, the pistol shrimp is considered more useful than harmful.
