阅读理解 ZANZIBAR, Tanzania(AP)－Hundreds of dead dolphins were washed up Friday along the shore of a popular tourist place on Zanzibar’s northern coast．Scientists have ruled out poisoning． It was not immediately clear what killed the 400 dolphins, whose dead bodies lay along a 4-kilometer coast of Nungwi, said Narriman Jidiwi, a marine biologist at the Institute of Marine Science in Zanzibar．But the bottleneck dolphins, which live in deep offshore waters, had empty stomachs, meaning that they could have got lost and had been swimming for some time to reorient themselves．They did not die from hungry and were not poisoned, Jidawi said． In the United States, experts were looking into the possibility that sonar(声波定位仪)from US submarines could have caused a similar incident in Marathon, Florida, where 68 deep-water dolphins stranded(搁浅)themselves in March, 2005． The deaths are a blow to the tourism industry in Zanzibar, where thousands of visitors go to watch and swim with wild dolphins．Villagers, fishermen and hotel residents found the dead bodies and told officials．Mussa Aboud Jumba, Zanzibar’s director of fisheries, went on state radio to warn the public against eating the dolphins’ meat, saying the cause of death had not been found． The Indo-Pacific bottlenose, commonly known as dolphins, are the most common species in Zanzibar’s coastal waters, with bottlenose and humpback dolphins often found in mixed-species groups． |
