根据佛罗里达洲迈阿密市罗森斯塔尔海洋和大气科学学院格鲁伯(Gruber)的研究,与一般人的观点相反,鲨鱼既有良好的视觉又有良好的听觉。格鲁伯报道说,事实上,鲨鱼凭着月光就能看清猎物。他测定了鲨鱼的视觉敏感性作为整个鲨鱼生活方式的研究的一部分。他采用短吻基齿鲨,以闪光配合电击处理进行训练,一天100次,连续8天。到了第二天,鲨鱼就能作出很可靠的反应。在训练结束之后,闪光逐渐减弱使鲨鱼习惯环境,同时,它的辨别力愈来愈强。在第二套实验中,格鲁伯训练鲨鱼选 According to Gruber, of Rosengarten’s College of Oceanography and Atmospheric Sciences in Miami, Florida, sharks have both good vision and good hearing, contrary to popular belief. Gruber reports that, in fact, sharks can see their prey with the moonlight. He measured the shark’s visual sensitivity as part of a study of the entire shark lifestyle. He used short-necked kennels to train with flash and shock handling for 100 times a day for eight consecutive days. The next day, the shark can make a very reliable response. After training is over, the flashes of light diminish the habit of the shark, and at the same time its discrimination becomes stronger and stronger. In the second experiment, Gruber trained sharks
