Several marine species have developed a magnetic perception that is essential for navigation and detection of prey and predators. One of these species is the transparent glass catfish that contains an ampullary organ dedicated to sense magnetic fields. Here we examine the behavior of the glass catfish in response to static magnetic fields which will provide valuable insight on function of this magnetic response. By utilizing state of the art animal tracking software and artificial intelligence approaches, we quantified the effects of magnetic fields on the swimming direction of glass catfish. The results demonstrate that glass catfish placed in a radial arm maze, consistently swim away from magnetic fields over 20 μT and show adaptability to changing magnetic field direction and location.

玻璃cat鱼的游泳方向对磁刺激有反应

几种海洋物种已经形成了一种磁性感知，这对于导航和检测猎物和掠食者至关重要。这些物种之一是透明的玻璃cat鱼，其中包含致力于感应磁场的壶腹器官。在这里，我们研究了玻璃cat鱼对静磁场的响应行为，这将为这种磁响应的功能提供有价值的见解。通过使用最先进的动物跟踪软件和人工智能方法，我们量化了磁场对玻璃cat鱼游泳方向的影响。结果表明，放在cat臂迷宫中的玻璃cat鱼会持续游离20μT以上的磁场，并显示出对变化的磁场方向和位置的适应性。
