Some of the species being protected are the world's fastest shark (the mako shark), wedgefishes and guitarfishes.

受保护的物种包括世界上最快的鲨鱼（灰鲭鲨）、圆犁头鳐科以及犁头鳐鱼。

One conservation group said this figure could be as high as 273 million. Forty countries disagreed that the mako shark was in danger.

一家保护组织称，这个数字可能高达2.73亿。有40个国家不认为灰鲭鲨面临危险。

So the faster-moving sharks like the white shark, mako shark, and blue shark, they have trouble with walls when they're put in a tank.

所以像大白鲨、灰靖鲨和蓝鲨这些移动快速的鲨鱼，在水槽内生活时，槽壁就成为了它们的障碍物。

We'll be tagging hammerhead sharks, tiger sharks and mako sharks trying to understand how they're leveraging the Gulf and their birthing, mating and full migratory patterns.

我们要追踪双髻鲨，虎鲨还有灰鲭鲨，设法搞清楚它们如何影响海湾，它们如何出生、如何交配、如何迁徙。

That means 3D models and essentially use that to predict then what are the structures that are under selection for evolution to actually take place and end up with this: So these are the mako shark.

这意味着 3D 模型，并基本上使用它来预测什么是正在选择进化的结构，以实际发生并最终得到：所以这些是灰鲭鲨。
