He paid annual visits there to enjoy the vivid beauty in thedepths of thepure sea.Once, with his underwater telescope and flashlight, Mark dived along the boundary between the steep reef and the area of seaweed conservation. Suddenly, an awesome Antarctic seal with sharp teeth appeared opposite him. Every cell in his body was scared to death. But soon, he was aware that he wasn't the target of an attack. With a neat wound in its lip caused by a shark, this grey seal was washed upside down by the tides time after time. But it tried to jog Mark as if to urge him to help it. So Mark abandonedfleeing away. With its teamwork, Mark used a net to drag the seal to the shallow water. Without a pause he helped it out after a simple operation and settled it in a narrow cave by theseaside. Every time he brought it tastyfish, it would yell and suck his hands happily. Witnesses said their anecdotesreflected a magic dimension of therelationship between humans and animals.马克和海豹马克用他的退休金在海岸边租了一处住所。他每年都去那儿欣赏洁净的大海深处那生动的美。有一次，马克带着他的水下望远镜和手电筒，潜到陡峭的暗礁和海草保护区间的分界线。突然，一只长着锋利的牙齿、使人畏惧的南极海豹出现在他对面。马克吓坏了，但是很快他就意识到他不是攻击的目标。这只灰色海豹的唇上有道鲨鱼咬出的整齐伤口，还时不时地被潮水冲得上下翻转。尽管如此，它却总是努力轻轻碰撞马克，似乎在催促他帮助它。于是马克放弃了逃跑。在这只海豹的合作下，马克用一张网把它拖到浅水区，并毫不停歇地给它动了一个简单的手术，帮助它解决了问题，然后将它安置在海边一个狭窄的洞里。每次当马克给它带来美味可口的鱼时，它就会高兴地大声叫唤，还吮吸他的手。目击者都说他们的轶事映射出人与动物关系中奇妙的一个方面。
