And flying towards you are a group of mysterious winged sea creatures known as mobula rays.

飛向的你的，是一群神秘、長著翅膀一般的神秘海洋生物，他們是鰏魟。

They're also called devil rays because of the horns on their head.

他們也被稱作魔鬼魚，因為他們頭上長了角的緣故。

Biologists don't know a lot about mobulas, but they do know that their brains are the largest of any fish species, which may explain why these rays exhibit increased social and cognitive abilities, akin to small mammals.

生物學家所掌握的鰏魟資訊不多，但他們確定鰏魟的腦是所有魚類生物中最大的，這也可以解釋為什麼鰏魟可以展現高度的社交與認知能力，與小型哺乳類動物雷同。

Every year, mobulas make seasonal migrations to warm waters in the Pacific, Atlantic, and Mediterranean.

鰏魟每年都會進行季節性的遷徙，到有溫暖海水的太平洋、大西洋與地中海。

Because of their elusive nature, these rays are notoriously difficult to observe in the wild.

因為他們天性神出鬼沒，他們因難以在野外被發現而臭名昭彰。

So biologists take advantage of this annual gathering to study them.

因此生物學家藉著這個年度聚會的機會來認識鰏魟們。

But these gatherings also attract danger.

但這個聚會同時會引來危險。

Mobulas are heavily poached for their gill plates, which are used in Chinese medicine.

鰏魟的鰓板可以作為中藥，因此鰏魟被大量盜獵。

And since this species has a low reproductive rate, there is limited ability to recover from population declines.

而由於這個生物的繁殖率較低，他們從因盜獵而造成數量驟減的恢復能力有限。

Activists are working to protect the rays and as of 2016, all nine species of mobula ray are listed under CITES Appendix II.

保育積極分子正努力的保護鰏魟而自 2016 起，所有 9 種鰏魟被列在瀕臨絕種野生動植物國際貿易公約的附錄二中。

Meaning trade and fishing are strictly regulated.

意味著交易與捕撈鰏魟是嚴格禁止的。

The hope is that this protection will help raise awareness about these beautiful creatures, and prevent mobula rays from disappearing altogether.

藉由這個保護措施希望可以提高保育這些美麗生物的意識，並預防他們永遠消失。
