    What you are hearing is a sound similar to what Alpheus randalli makes.  As you can hear it is definitely not a quiet creature at all! 

  • When listening to the noise of the Pistol Shrimp, the snapping sound is similar to burning a bunch of dry sticks or frying fat. (Johnson, et. al. 1947)

  • The first Alpheus randalli was collected with a Hawaiian spear, which distorted the anterior part of the body for observation (Banner and Banner 1980).

  • The Pistol Shrimp was featured as the number one loudmouth on Animal Planet's show, The Most Extreme.  Click here to see the clip!

  • The species of goby that Alpheus randalli, Amblyeleotris sp., was first discovered living with was also a newly discovered species (Banner and Banner 1980).

  • Snapping sounds from the shrimp increase for a short time just after sunset and just before sunrise (Johnson, et al. 1947).

  • The force of the snap of the claw is powerful enough to kill small organisms like small fish, crabs and shrimp, at close range (Masterson 2008).

  • Color is an important element to consider when identifying species in the Alpheus genus (Spence and Knowlton 2008).

  • It is believed that the orbital hoods that protect the eyes from combat evolved before the snapping claws in the Alpheidae family (Anker 2006).

  • Scientists often use paint brushes to tickle the shrimp to trigger the snap (BBC News 2000).
