Description
Boombox Fish This species of boombox fish {ancestor gobio gobio} dwells in the river FLuvasia of Adlesia, in waters that are more still and gentle. They can be semi murky but the preference is for clearer waters with sandy or gravely bottoms.The males and females spend their time in separated shoals as they forage for detritus, algae, plankton, frog/fish eggs, and tiny invertebrates. This fish has developed an extraordinary way of communicating with one another- while lacking teeth, they possess gill rakers with which they make a chewing motion, creating squeaking , clicking, and chattering noises, with a complexity and structure similar to some birds.They also possess a weberian organ- a structure composed of tiny bones originating from it's vertebrate. These bones connect the inner ear to the swim bladder, acting as an amplifier of sound waves. And in addition to that is their throat sac which, which can broadcast the noise even further to reach as many fish as possible. This sac can not only create a small 'boom' {earning them their name} but blend it with its teeth noises to make incredibly unique songs, taught by the fathers to their male offpsring. This sac is only used during breeding season to attract the attention of females. During the warmest part of summer the males, instead of chorusing together, will disperse, each finding its own secluded area where its song can be heard in peace. They are able sing in such a way as it is hard for a predator to pinpoint exactly where the noise is coming from. After breeding the eggs will drift through the water and settle in the stones.
