They catch up with Puck and Semu, she leads him out into deep water for the first time, which is a first big challenge.

他们想到了帕克和莎木，看起来帕克想把莎木带到深水区。这对它来说是个挑战。

Deep water is a much more dangerous place for Semu, he could easily get lost.

He's still learning his mother's call.

它还在学习妈妈的叫声。

Sensing the danger, Semu stays closer to her side, mirroring her every move as he swept along in Puck's history.

感到有危险，莎木就会紧靠着妈妈。模仿妈妈的动作就可以借助它的动力，往前游。

Semu was indeed a little bit more coordinated today, and low like skittish, keeping it well with mum

Normally, caves can only dive a meter or so in their first week of life, but Semu is diving deeper and for longer than any other calves the researchers have seen before.

通常，刚出生的小海豚只能下潜一米深。但莎木潜的要更深一点，更长一点，队员们从来没遇到过。

好兆头。

It's Semu doing so well, Puck's finally able to start fishing again.

莎木干的不错，帕克终于可以吃点东西了。

She heads for a bait ball.

它往鱼群游去。
