第2784期:Record warm seas help to bring extraordinary new species

The data shows the average surface temperature of UK waters in the seven months to the end of July was more than 0.2 degrees celsius higher than any year since 1980. Now that might not sound much, but the UK's seas are now considerably warmer than even a few decades ago.数据显示，在截至七月底的七个月里，英国海水的平均表面温度比 1980 年以来的任何一年都高出零点二摄氏度以上。这个温度升幅也许听起来不算太多，但是如今英国海水的温度已经比几十年前高出了相当多。

Scientists and amateur naturalists in the south-west of England have observed a remarkable range of species, not usually seen in UK waters. They include large numbers of bluefin tuna and octopuses, as well as mauve stinger jellyfish, conger eels, humpback whales and even the world's second-largest whale species, the fin whale.科学家和业余博物学家在英格兰的西南部观察到了一系列非同寻常的物种，这些物种在英国海域中并不常见。这其中包括大量的蓝鳍金枪鱼和章鱼，以及紫纹海刺水母、康吉鳗鱼、座头鲸，甚至还有世界第二大鲸鱼物种——长须鲸。

But there have also been significant declines in cooler water species, including cod and haddock.但是，喜冷生物的数量也出现了显著下降，比如鳕鱼和黑线鳕。
