这些捕食者在做什么？ What are these predators doing?

世界野生动物日

今天是世界野生动物日，让我们来了解了解虎鲸（逆戟鲸）相关的知识吧。虎鲸是顶级掠食者，处于食物链的顶端。虎鲸拥有无与伦比的捕猎技能，但目前还没有任何有关虎鲸在野外杀人的记录。虎鲸的食物通常是海洋生物，如鱼、企鹅、鲨鱼和鲸鱼。不过“虎鲸”这个名字其实并不准确。虎鲸不是鲸鱼，而是海豚。

Killer whales in Spildra, Norway

Today is World Wildlife Day and there is perhaps no better occasion to brush up on your killer whale—also known as an orca whale—knowledge. Killer whales are apex predators, which means they are at the top of the food chain. Orcas exhibit unmatched hunting skills, but there have not been any documented cases of orcas in the wild killing humans. Their diet usually includes a smorgasbord of sea creatures, such as fish, penguins, and even sharks and whales. Did you know that the name ‘killer whale' is a misnomer? Killer whales are not actually whales but dolphins. It is believed they were nicknamed ‘killer whale' by Spanish sailors who saw them hunting whales.
