Genus: Alpheus. [10] It corresponds to a peak pressure level of 218decibels relative to one micropascal (dB re 1Pa), equivalent to a zero to peak source level of 190dB re 1Pam. Au and Banks measured peak to peak source levels between 185 and 190dB re 1Pam, depending on the size of the claw. We knew the bubbles were there, but we didnt know what they looked like. So his team sought to unravel the mystery by simulating what happens after the shrimp shuts its claw at different speeds.

We have capitalized on this evolutionary cacophony by utilizing the power of bubble collapse dynamics for military defense. [4] Webster, M. and A. McEwen.

At a volume of about 200 decibels louder than a .22 calibre rifle shot these pops are some of the loudest in the ocean, second only to sperm whale clicks. Luckily for snorkelers and divers, the striking distance is only about three millimeters from the tip of the snapping claw to the imploding bubble.
