What has science done?

I saw an article about that little guy a few days ago....I love jumping spiders....soooo cute!

...plus the fact they developed to eat mostly plant matter is extremely interesting.

 

I guess that one should NOT guard the backdoor into Mordor.

Wikipedia to the rescue!

 

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 shrimp 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. It corresponds to a zero to peak pressure level of 218 decibels relative to one micropascal (dB re 1 μPa), equivalent to a zero to peak source level of 190 dB re 1 μPa at the standard reference distance of 1 m. Au and Banks measured peak to peak source levels between 185 and 190 dB re 1 μPa at 1 m, depending on the size of the claw. Similar values are reported by Ferguson and Cleary. 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). 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.
