The pistol shrimp emits a sound that is louder than a gunshot.
The snap reaches 210 decibels. An actual gunshot usually only reaches between 165-175 decibels. Pistol Shrimps rank among Sperm Whales and Baleen Whales for the loudest creatures in the ocean. Sperm Whale clicks reach around 230 decibels, while the calls of Baleen Whales reach around 188 decibels. Shrimps live in large colonies, so the snapping of hundreds of shrimps create significant noise in the ocean.
