Both types strike by rapidly unfolding and swinging their raptorial claws at the prey, and are capable of inflicting serious damage on victims significantly greater in size than themselves. In smashers, these two weapons are employed with blinding quickness, with an acceleration of 10,400 g and speeds of 23 m/s from a standing start [6], about the acceleration of a .22 calibre bullet [7][8]. Because they strike so rapidly, they generate cavitation bubbles between the appendage and the striking surface [6]. The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newton that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike; first by the claw and then by the collapsing cavitation bubbles that immediately follow [9]. Even if the initial strike misses the prey, the resulting shock wave can be enough to kill or stun the prey.

The snap can also produce sonoluminescence from the collapsing bubble. This will produce a very small amount of light and high temperatures in the range of several thousand kelvin within the collapsing bubble, although both the light and high temperatures are too weak and short-lived to be detected without advanced scientific equipment. The light emission and temperature increase probably have no biological significance but are rather side-effects of the rapid snapping motion. Pistol shrimp produce this effect in a very similar manner.

The snapping shrimp competes with much larger animals, like the Sperm Whale and Beluga Whale, for the title of ‘loudest animal in the sea’. The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. The pressure is strong enough to kill small fish and shatter glass.[7] It corresponds to a zero to peak pressure level of 218 decibels relative to one micropascal (dB re 1 ?Pa), equivalent to a zero to peak source level of 190 dB re 1 ?Pa at the standard reference distance of 1 m. Au and Banks measured peak to peak source levels between 185 and 190 dB re 1 ?Pa at 1 m, depending on the size of the claw.[8] Similar values are reported by Ferguson and Cleary.[9] The duration of the click is less than 1 millisecond.

The snap can also produce sonoluminescence from the collapsing cavitation bubble. As it collapses, the cavitation bubble reaches temperatures of over 5,000 K (4,726.85 degrees Celsius).[10] In comparison, the surface temperature of the sun is estimated to be around 5,778 K. The light is of lower intensity than the light produced by typical sonoluminescence and is not visible to the naked eye. It is most likely a by-product of the shock wave with no biological significance. However, it was the first known instance of an animal producing light by this effect. It has subsequently been discovered that another group of crustaceans, the mantis shrimp, contains species whose club-like forelimbs can strike so quickly and with such force as to induce sonoluminescent cavitation bubbles upon impact.[11]

:wow:

Yeah…those lil fuckers got the seiken AND futae no kiwami.

We only see less than one percent of the electromagnetic spectrum, therefore over 99 percent of the Universe is invisible to us.
