Definition of paddlefish in English:



  • A large mainly freshwater fish related to the sturgeon, with an elongated snout.

    • ‘American paddlefish are mainly freshwater fish but can survive in brackish water.’
    • ‘Since sturgeons and paddlefish have lost many traits of most bony fish - they lack scales and have a cartilaginous skeleton - their fossil records are very sparse.’
    • ‘Within bony fishes, non-neopterygians (bichirs, paddlefish, and sturgeons) have relatively smaller brains than those in the vast majority of teleosts.’
    • ‘The tail fin of most ray-finned fish, with the exception of sturgeons and paddlefish, is homocercal, nearly symmetrical about the midline.’
    • ‘Within the Chondrostei, only sturgeons, bichirs and paddlefishes survive today, and many are threatened.’
