Sound localization by fish was long considered physically impossible, until it was shown behaviorally. How do they do it?
The fantastic Johannes Veith, Thomas Chaigne and team dove into this question with Danionella:

The mechanism for directional hearing in fish - Nature

A study demonstrates that the fish Danionella cerebrum is able to discriminate the direction of sound by comparing the relative phase of pressure and particle motion.

Danioella in with a BANG!

#GiveTheDrummerSome #SizeIsntEverything

One of world’s smallest fish found to make sound as loud as a gunshot

Scientists discover how Danionella cerebrum, measuring width of adult human fingernail, can create noises exceeding 140 decibels

How can the tiny glassfish Danionella cerebrum, just over 1 cm long, produce high-amplitude communication sounds exceeding 140 dB? We found that it uses a fascinating drumming mechanism involving acceleration at over 2000 g:
