It is well accepted that light from the moon is a result of biolumonence; probably fungus or bacteria. There are times however when the moon is brighter than normal. The brightness at these times most likely coincides with the feeding/breeding times of lunar crestation-like life. However, they use a light generating tenique known as sonoluminescence, much like the Alpheidae Shrimp here on earth.
Now, you can't hear them because of the vaccum seperating the two bodies. Being that these shrimp eat the fungas/bacteria, their light generating has evolved to kill the local biolumoncent life. The light created from sonoluminescence is the most likely cause of the plant killing effects of the moon that Ichi proved. It's so effective at close range on the moon that the combined force of all these creatures is what kill earth-plants.
These shrimp-like creatures, presumably, migrate across the surface of the moon as the local fungas/bacteria is in bloom. This, combined, accounts for the moons waxing and waining.

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. As it extends out from the claw, the bubble reaches speeds of 60 miles per hour (97 km/h) and releases a sound reaching 218 decibels.[8] The pressure is strong enough to kill small fish.[9] 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.[10] Similar values are reported by Ferguson and Cleary.[11] 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 (4,700 °C).[12] In comparison, the surface temperature of the sun is estimated to be around 5,800 K (5,500 °C).
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.[13]
The snapping is used for hunting (hence the alternative name "pistol shrimp"), as well as for communication. When feeding, the shrimp usually lies in an obscured spot, such as a burrow. The shrimp then extends its antennae outwards to determine if any fish are passing by. Once it feels movement, the shrimp inches out of its hiding place, pulls back its claw, and releases a "shot" which stuns the prey; the shrimp then pulls it to the burrow and feeds.
and you need bubbles for sonoluminesence, and normally achieved in water or a liquid.
Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. This cavity may take the form of a pre-existing bubble, or may be generated through a process known as cavitation. Sonoluminescence in the laboratory can be made to be stable, so that a single bubble will expand and collapse over and over again in a periodic fashion, emitting a burst of light each time it collapses. For this to occur, a standing acoustic wave is set up within a liquid, and the bubble will sit at a pressure anti-node of the standing wave. The frequencies of resonance depend on the shape and size of the container in which the bubble is contained.
Some facts about sonoluminescence:
The light flashes from the bubbles are extremely short—between 35 and a few hundred picoseconds long—with peak intensities of the order of 1–10 mW.
The bubbles are very small when they emit the light—about 1 micrometre in diameter—depending on the ambient fluid (e.g., water) and the gas content of the bubble (e.g., atmospheric air).
Single-bubble sonoluminescence pulses can have very stable periods and positions. In fact, the frequency of light flashes can be more stable than the rated frequency stability of the oscillator making the sound waves driving them. However, the stability analyses of the bubble show that the bubble itself undergoes significant geometric instabilities, due to, for example, the Bjerknes forces and Rayleigh–Taylor instabilities.
The addition of a small amount of noble gas (such as helium, argon, or xenon) to the gas in the bubble increases the intensity of the emitted light.
Spectral measurements have given bubble temperatures in the range from 2300 K to 5100 K, the exact temperatures depending on experimental conditions including the composition of the liquid and gas.[1] Detection of very high bubble temperatures by spectral methods is limited due to the opacity of liquids to short wavelength light characteristic of very high temperatures.
Writing in Nature, chemists David J. Flannigan and Kenneth S. Suslick describe a method of determining temperatures based on the formation of plasmas. Using argon bubbles in sulfuric acid, their data show the presence of ionized molecular oxygen O2+, sulfur monoxide, and atomic argon populating high-energy excited states, which confirms a hypothesis that the bubbles have a hot plasma core.[2] The ionization and excitation energy of dioxygenyl cations, which they observed, is 18 electronvolts. From this they conclude the core temperatures reaches at least 20,000
