In October 2008, a team from British and Japanese institutes discovered a shoal of Pseudoliparis amblystomopsis at a depth of about 7,700 m (25,300 ft) in the Japan Trench. These were, at the time, the deepest living fish ever recorded on film.[3] The record was surpassed by a type of snailfish filmed at a depth of 8,145 m (26,700 ft) in December 2014,[4] and extended in May 2017 when another snailfish was filmed at a depth of 8,178 m (26,800 ft).[5] This deepest-water so-called ethereal snailfish remains undescribed,[2] but a close relative found only slightly shallower in the Mariana Trench was described as Pseudoliparis swirei in late 2017.[6][7]
