The hearing sensitivity improves considerably in this way. The anterior part of the swim bladder functions in specialized fish species similar to an ear drum. Up to now the effects of the different swim bladder morphologies have not been investigated in detail in cichlid fishes. The...

Two species, Steatocranus casuarius (also known as the Lionhead, Blockhead or Humphead) and Steatocranus tinanti are relatively common in the...
