Where their ecological ranges overlap, ecotypes rarely interact and do not appear to interbreed.

在生幅度重叠的地方，生很少用，似乎也不会杂交。

Distinct killer whale populations are known as " ecotypes" and can differ in size, colour and body proportion.

不同的虎鲸种群被称为“生”，其大小、颜色和身体比例可能有所不同。

The most studied killer-whale ecotypes are the three that occupy the north-east Pacific coastline, from northern Alaska to southern California.

研究最多的虎鲸生是占据东北太平洋海岸线（从阿拉斯加北部到加利福尼亚南部）的三种虎鲸生。

Different killer-whale ecotypes even communicate using distinct " dialects" made of clicks, whistles and calls, with " accents" that differ between pods.

不同的虎鲸生甚至使用由滴答声、口哨声和叫声组成的不同“方言”进行交流，不同群体之间的“口音”也不同。

And we've got this new classification system, the ecotypes, pointing towards more tailored therapies, plus this potential universal target, inectin-2-tiget.

我们有了新的分类系统——生，这指向了更精准的治疗方案，再加上这个潜在的通用治疗靶点，Nectin-2-TIGIT。

Most of what makes killer-whale ecotypes distinct is their culture-socially learned behaviours that killer whales are known to transmit from one generation to the next.

虎鲸生的独特之处在于它们的文化：众所周知，虎鲸会将社会习得行为代代传。
