是侏三趾树懒的栖息地Home to the pygmy three-toed sloth.
这是一只雄性树懒This is a male
在这里生活得十分惬意and life here suits him well.
红树林为他提供食物Mangroves provide all the leaves he can eat
也没有天敌前来叨扰and there are no predators to worry him.
岛上的生活似牧歌般悠闲Island life may seem idyllic
但这是有代价的but it comes at a price.这座岛上只有几百只雌性侏三指树懒There are only a few hundred pygmy sloths in existence.
而他需要配偶And he needs a mate.
这雌性的叫声That's an enticing call...
好生诱人..from a female.
就在不远的某个地方Somewhere out there.
对树懒来说 这反应堪称迅猛And this, for a sloth, is a quick reaction.
但问题是 中间隔着一渊深潭The problem is, there's deep water between them.
那么一只气血方刚的树懒会怎么做呢So what should any red-blooded sloth do?
当然是游过去Swim, of course.
那会是她吗Could this be her?
他尽全力加快速度He does his best to put on a turn of spee
D.
但叫的不是她But she's not the one.
这只母树懒已经有了一只幼崽She already has a baby
在幼崽六个月后长大离开之前and she won't mate again until it leaves her
她不会再次交配in about six months'time.
即使生活在天堂之岛也会有限制Even life on a paradise island can have its limitations.
但至少她就在不远处But at least she can't be far away.

这一只并不排斥She's receptive.目前为止 一切顺利So far, so goo
D.
但他误入别人的领地But he's strayed into someone else's patch.
另一只雄性巨蜥认为它才是这里的王Another huge male thinks he is the king here.
岛屿上空间有限Space being limited on islands,
巨蜥的地盘时常重叠dragon territories overlap
导致冲突不断and that creates continual conflict.
在巨蜥族群里 体型决定一切In dragon society, size is everything.
但如果双方体型相当But if rivals are closely matched,
鹿死谁手就难以预料the outcome can be uncertain.
强壮的尾巴一击如同重锤Muscular tails strike with the power of sledgehammers.

生活着最奇异的爬行动物is the home of one of the strangest of reptiles.
海鬣蜥Seagoing iguanas.
它们是素食者They are vegetarians,
但由于岛上没有能吃的食物but since there's little food for them on the land,
所以海鬣蜥以海底的植物为食marine iguanas graze on the sea floor.

屏住呼吸长达半小时and hold his breath for half an hour.
仅在费尔南迪纳岛上There are more than , individuals
