A male Danionella cerebrum fish<\/p>\n

One of the world\u2019s smallest fish, measuring just 12 millimetres long, can make a sound registering more than 140 decibels \u2013 about as loud as firecrackers being set off.<\/p>\n

Danionella cerebrum<\/em> is a tiny species of fish that is native to small streams along the Bago Yoma mountain range in Myanmar. It has the smallest known brain<\/a> of any vertebrate in the world.<\/p>\n

\u201cWe study this fish primarily for neuroscience, because they\u2019re so small and transparent,\u201d says Verity Cook<\/a> at Charit\u00e9 \u2013 Berlin University Medicine in Germany. But the fish are so loud that, even when just walking past their tanks, you can hear audible pulsing sounds, she says.<\/p>\n
