8月14日报道,港媒称,一个国际科学家小组完成了对八爪鱼(又称章鱼)的基因组排序,发现八爪鱼有约3500条世上独一无二的基因,让它们聪明无比,能够改变皮肤的颜色和纹理,分散的大脑亦使它们的8条手臂能独立移动。据香港《明报》网站8月14日报道,这项研究由诺贝尔奖得主、日本冲绳科学技术大学院大学(OIST)教授布伦纳(Sydney Brenner)发起,对常见的加州双斑蛸(California two-spot octopus)90基因组作排序和]释

8月14日报道,港媒称,一个国际科学家小组完成了对八爪鱼(又称章鱼)的基因组排序,发现八爪鱼有约3500条世上独一无二的基因,让它们聪明无比,能够改变皮肤的颜色和纹理,分散的大脑亦使它们的8条手臂能独立移动。

据香港《明报》网站8月14日报道,这项研究由诺贝尔奖得主、日本冲绳科学技术大学院大学(OIST)教授布伦纳(Sydney Brenner)发起,对常见的加州双斑蛸(California two-spot octopus)90基因组作排序和]释。研究结果发表在最新一期《自然》期刊上。

在无脊椎动物当中,头足纲动物的神经系统是最大的。头足纲的基因组大而复杂,测序和组装都具有挑战性。今次研究发现,八爪鱼和其他无脊椎动物基因组之间有着惊人差异,它们约3.3万组基因中,约3500组都是其他动物所没有,当中很多组基因都是负责大脑、爪、吸盘、和隐身能力。

报道称,联手研究的芝加哥大学学者拉格斯代尔(Clifton Ragsdale)表示,有着巨大、高度发达的大脑,像八爪鱼这类头足纲动物是地球最聪明动物,显示出高级的解决问题和学习行为。

如果不幸被掠食者咬住,毯子章鱼还会自断腕足逃离,类似蜥蜴的断尾求生。毯子章鱼是章鱼中的异类,它们不会喷出墨汁来吓跑掠食者,也从来不在海床上活动。
