While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada.

然而紫脚趾和敏锐视力的猎手只是编造的一个例子，在加拿大西部一种真正存在的三剌鱼就能证明刚才所说的观点。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada.

紫色的脚趾，敏锐的视力都只是编出来的例子，加拿大西部的三刺鱼为我们展示进化历程，这是一种真正存在的动物。

While purple-toed, keen-eyed hunters are just a made up example, a real animal that demonstrates this is the three-spined stickleback fish of western Canada.

紫色脚趾、眼神尖锐的猎人只是拼凑起来的例子，而一种证明了这个理论的真实的动物是加拿大西部的三刺棘鱼。

The most pathogenic isolate, VIB 645, contained two closely related hemolysin genes, which were cloned and sequenced. In this study, vhhA was cloned into an expression plasmid pET-24d.

本研究将哈维氏弧菌的溶血素基因vhhA克隆到大肠杆菌的表达载体pET-24d，VHH溶血素作为一种带六个组氨酸的融合蛋白在大肠杆菌表达菌株BL21(DE3)中得到了过量表达，重组大肠杆菌及其培养上清液在鱼血平板上有很强的溶血活性。

Frontosas are particularly intelligent fish and adapt very quickly according to the local circumstances and availability of food.

六间是一种很聪明的鱼，可以很快适应当地的环境和食物多少。

Introduction through a friend, I am now taking a called the "devil fish" of weight loss drugs, hoping to improve my situation at present, do not know whether it can be, experts can help, thank you!

通过朋友介绍，我现在服用一种叫做&魔鱼&的减肥药品，希望能改善一下我现在的状况，不知道是不是可以，请专家能给予帮助，谢谢！

Low levels of straying are crucial, since the process provides a source of novel genes and a mechanism by which a location can be repopulated should the fish there disappear.

较低程度上鱼的离群至关重要，因为这个过程提供了新的基因来源和一种机制，通过这种机制，那些鱼群消失的地方能够得以重新繁荣起来。
