The blue or sperm whale is the loudest animal (230db). This is the second loudest animal.
Tiger pistol shrimp or Snapping shrimp (200db)
They have a claw that shoots jets of water at very high speeds. The speed is high that it creates an air bubble, which implodes and creates a shock wave that kills any fish in the range of 2 meters --louder than a gunshot. The implosion of the bubble also creates temperatures at its center as high as that of the sun which cause a flash of light to appear each time this shrimp shoots his pistol.
