文章2

Imagine boating down the Amazon River, minding your own business-calmly keeping an eye out for alarmingly large snakes--and a curious pink dolphin appears to swim alongside.

想象一下，沿着亚马逊河划船，心无旁骛地注意着自己的事情——静静地留意着惊人的巨蛇——还有一只好奇的粉红海豚在旁边游泳。

While this may seem like a mythical creature, pink dolphins do exist in the Amazon region.

虽然这看起来像是神话中的生物，但粉红海豚确实存在于亚马逊地区。

The Amazon river dolphin is a giant among its species.

亚马逊河豚是其物种中的巨兽。

It can measure up to 2 meters long and weigh around 204 kilograms.

它的长度可达2米，重约204公斤。

Size isn't the only thing that sets the Amazon river dolphin apart.

尺寸并不是亚马逊河豚与众不同的唯一因素。

Thriving in South American rivers and temporary lakes caused by seasonal flooding, this freshwater dolphin is sometimes shockingly pink.

这种淡水海豚在南美洲的河流和季节性洪水造成的临时湖泊中繁衍生息，有时粉红色的颜色令人震惊。

Although born gray, males of the species are easily identified as they enter adulthood by a decisive pink shade.

虽然生下来是灰色的，但成年后，雄性很容易被确定的粉红色色调辨认出来。

Their unusual coloring is believed to be the result of scar tissue from dolphin fights-whether play fighting or a serious bid for a mate.

人们认为它们的不同寻常的颜色是海豚打架时留下的疤痕组织造成的，不管是打架还是争夺配偶。

The deeper the pink, the more attractive the males are believed to be, and the older the male, the more pink it will have.

粉色越深，男性被认为越有魅力，而男性年龄越大，粉色就会越多。

There's also a theory that this color helps the dolphins more readily blend in with their surroundings.

还有一种理论认为，这种颜色有助于海豚更容易融入周围的环境。

During heavy rains, rivers along the Amazon rainforest turn a pink shade, and with their pink coloring， male dolphins are harder to detect.

在大雨期间，亚马逊雨林沿岸的河流会变成粉红色，雄性海豚的粉红色更难被发现。

The Amazon wetland system, fed by the Amazon River, is a crucial place for pink dolphins to breed, and since 2018 has been granted internationally protected status.

由亚马逊河供水的亚马逊湿地系统是粉红海豚繁殖的重要场所，自2018年起被授予国际保护地位。
