1 WhalesWhales are the largest animals ever known to have lived on Earth and they like to sing and whistle to communicate. Blue whales make very deep low-pitched sounds that have been recorded as high as 188 decibels. The sounds they produce are louder than a jet engine and are a lot louder than a human ear would be able to tolerate. The loudest species of whale is the Sperm Whale, whose clicking sounds can reach 230dBs. Although these clicks only last a little over 10 milliseconds, another Sperm Whale can hear the clicks up to 10 miles away.
2 Tiger Pistol ShrimpTiger pistol shrimp is part of the family Alpheidae of shrimp and is considered the second loudest animal on the planet. This small animal that lives in the ocean creates a sound of about 200 db which is louder than a gunshot. Tiger pistol shrimp have a claw that shoots jets of water at very high speeds. The speed is high that it creates an air bubble. When the bubble implodes it creates a shock wave that kills any fish in the range of 2 meters. The implosion of the bubble also creates temperatures at its centre as high as that of the sun which cause a flash of light to appear each time this shrimp shoots his pistol.
