科学家发现，南非虎鲸杀死大白鲨的目的就是要吃 “鱼肝“，它们怎么知道鱼肝油有营养？

Great white sharks are being killed in disturbing fashion off South Africa, and experts are helpless to prevent further assaults. That’s because orcas are believed responsible for the killings. At least three white shark carcasses have washed ashore recently with similar injuries, each with its liver removed.

• 估计是鲨鱼肉不好吃。要不渔民为什么直接割了鱼翅后把鲨鱼扔回海里呢？ -多情易老- ♂ (0 bytes) () 05/09/2017 postreply 23:49:26
