海洋生物学家艾伦·贾米森曾一度放弃在水下栖息地亲眼见到地精鲨的念头。毕竟,它们生活在数千英尺深的完全黑暗水域中,自100多年前被发现以来,人们仅在渔民捕获并将其带上水面时才能观察到它们。
但两年前,当他使用遥控诱饵相机探索地球上第二深的海沟——太平洋汤加海沟时,情况发生了改变。
“地精鲨是我从未想过能亲眼看到活体的深海魅力物种之一,能拍到它们已经令人惊叹,而随后得知夏威夷的同事也拍到了一只,更是难以置信,”明德罗-西澳大学深海研究中心创始主任贾米森在本周发布的一份研究配套新闻稿中表示。该研究记录了两起这种难以捉摸的深海生物的目击事件。

这份发表在《鱼类生物学杂志》上的研究详细记录了两起通过相机拍摄到地精鲨的目击事件。
第一起发生在2019年,但当时无人知晓。研究作者亚伦·犹大在与深海动物研究中心的同事交流时得知,2019年海洋探索信托基金在罗伯特·巴拉德拥有的水下勘探船“鹦鹉螺号”上的考察队——罗伯特·巴拉德正是发现泰坦尼克号残骸的人——可能曾用相机拍到过一只地精鲨。
回看录像时,犹大收获了惊喜。这只鲨鱼是在探索太平洋靠近贾维斯岛和帕尔米拉环礁等极其偏远区域时被拍到的。
“看到所有深海鲨鱼中最具标志性的物种在自然栖息地中存活且状态健康,是一种独特的荣幸,”夏威夷大学马诺阿分校海洋学系研究员犹大在谈及这两项发现时表示。“我还对该物种被发现的深度感到非常惊讶。在汤加海沟斜坡上的观测点,比已知该物种的生存深度还要深近700米。”
换句话说,2019年和2024年的这两次发现不仅因为是首次通过相机拍到活体地精鲨而具有启发性,还帮助科学家进一步了解了这种动物的自然栖息地。

根据该研究,得益于2019年中太平洋的目击记录,地精鲨的活动地理范围大幅扩大,而2024年的发现则将鼠鲨目鲨鱼的已知生存深度下限延伸了108米。
地精鲨的名字源于其独特且略带惊悚的外形。这种鲨鱼平均体长约12英尺,拥有粉色柔软的躯体和滑稽的大鼻子,下方隐藏着一口锋利的尖牙。据美国鱼类和野生动物管理局介绍,地精鲨是被称为“活化石”的物种之一,因为它们是其所属的尖吻鲛科目前仅存的成员,该科的历史可追溯至1.25亿年前。
“我们仍然开展自然史研究真的非常重要,”犹大在一份声明中说道。“像这样的新发现表明,我们的深海家园还有太多未知等待探索。鉴于地精鲨的地理范围 newly-expanded?不对,是新拓展的,哦对,鉴于地精鲨的地理范围 newly-expanded?不,正确翻译是“鉴于地精鲨的活动地理范围已大幅拓展”,该物种如今可以被纳入区域管理和各国的生物多样性名录,而此前我们甚至不知道它的存在!”
Goblin shark seen alive in natural habitat for the first time: “The most iconic of all the deep-sea sharks”

Marine biologist Alan Jamieson had given up on seeing a goblin shark in its underwater home. After all, they live thousands of feet underwater in total darkness and since being discovered over 100 years ago, had only been observed when caught by fishermen and brought to the surface.
But that changed two years ago when exploring the Pacific Ocean’s Tonga Trench — the second-deepest point on Earth — with a remote, baited camera.
“The Goblin Shark is one of these deep-sea charismatic animals that I never thought we’d see alive, and then to do so was amazing, but to then learn that colleagues in Hawai’i also saw one was just incredible,” Jamieson, the founding director at Minderoo-UWA Deep-Sea Research Center, said in a press release accompanying a study released this week on not one, but two sightings of the elusive deep-sea creature.

The study, published in the Journal of Fish Biology, details two observations of the goblin shark on camera.
The first came in 2019, but no one even knew it at the time. In speaking with colleagues at the Deep-Sea Animal Research Center, study author Aaron Judah learned a 2019 Ocean Exploration Trust expedition on the M/V Nautilus — the underwater exploration ship owned by Robert Ballard, who found the wreck of the Titanic — might have seen a goblin shark on camera.
In looking back through the video, Judah hit the jackpot. The shark was spotted when exploring extremely remote areas of the Pacific near locations like Jarvis Island and the Palmyra Atoll.
“Seeing the most iconic of all the deep-sea sharks alive and looking healthy in its natural habitat is a unique honour,” Judah, a researcher in the Department of Oceanography at the University of Hawaii at Mānoa, said in a statement of the two discoveries. “I was also very surprised about how deep this species was found. The observation from the slope of the Tonga Trench is nearly 700 meters deeper than this species was known to live.”
In other words, the discoveries in 2019 and 2024 were not only enlightening for being the first time seeing the shark on camera, but also in helping scientists learn more about the animal’s natural habitat.

The geographic range of where the goblin shark roamed expanded considerably thanks to the mid-Pacific sighting in 2019, while the 2024 find extended how deep lamniform sharks could be found by 108 meters, according to the study.
The goblin shark’s name comes from its unique, and slightly terrifying, appearance. The shark, which is about 12 feet long on average, has a pink, squishy body and comically large nose hiding a set of razor-sharp teeth underneath. Goblin sharks are one of a species known as “living fossils,” since they are the only one left living in their family (Mitsukurinidae), which goes back 125 million years, according to the U.S. Fish and Wildlife Service.
“It is really important that we still perform natural history work,” Judah said in a statement. “New discoveries like this demonstrate that there is still so much to explore in our deep ocean home. Given the newly-expanded geographic range of the goblin shark, this species can be included in regional management and a nationʻs biodiversity list, whereas, beforehand we didn’t know it was even there!”
