That epitome of rugged wildness, the grizzly bear, seems to be the only species other thanhumans to have invented the comb.
粗犷野性的象征灰熊,看来是除了人类以外唯一一种发明了梳子的动物。
Dr Deecke made this discovery while studyinggrizzly-bear behaviour from a small boat in Glacier Bay National Park, Alaska, on July 22nd2010.
这一点是Deecke博士于2010年7月22日在阿拉斯加冰河湾国家公园一艘小船上研究灰熊习性时发现的。
After a period of play-fighting with another bear and a short bout of feeding on a beachedwhale carcass, a bear of between three and five years of age, sex unknown, waded into theshallows of the bay.
一只灰熊在与另一只熊打闹了一阵并吃了一点被冲到沙滩上的鲸鱼尸体后,涉水来到了海湾的浅滩中。
Once there, it picked up a fist-sized rock and carefully rotated it for about a minute beforedropping it back into the water.
在那,它捡起了一块拳头大的石头,小心翼翼地旋转了约一分钟后,将其扔回水中。
Moments later, it picked up another, of similar size, and again rotated it.
片刻之后,它又捡起了另一块差不多大小的石头旋转起来。
This time, rather than discarding the stone, it held it against its muzzle and started to rub.
