Researchers recently discovered a new species of pistol shrimp that creates such a violent underwater vibration, by flapping its large claw, that it disables and even kills small fish. The shrimp, anointed with the name Synalpheus pinkfloydi, is characterized by its relatively immense and almost glowing red pincer-like appendage. While not unique in this regard, this crustacean is noteworthy for the way it immobilizes its prey. Using rapid claw movements and closures, Synalpheus pinkfloydi creates high pressure in the water followed by bubbles that burst. The resulting implosion is one of the loudest sounds in the ocean, reaching as high as 210 decibels (dB). The sound is intense enough to stun or even kill a small fish, hence the classification, pistol. As a point of reference, the threshold of pain for humans is 140 decibels. Rock bands typically perform at sound levels of 100-129 dB, with the loudest concerts reaching 139 dB.

According to researcher Sammy De Grave, the Head of Research at the Oxford University Museum of Natural History, “I have been listening to Floyd since The Wall was released in 1979, when I was 14 years old. The description of this new species of pistol shrimp was the perfect opportunity to finally give a nod to my favorite band”.
