As part of a two-month expedition to the deep pits around Japan in the North Pacific Ocean, remote-controlled cameras have indeed observed this unknown species of slugfish of the genus Pseudoliparis in the Izu-Ogasawara

This expedition by a team from the University of Western Australia (UWA) and Tokyo University of Marine Sciences was part of a ten-year study of the world's deepest fish populations .

A few days later, the team also captured two specimens of the

Pseudoliparis belyaevi

species in traps placed 8,022 meters underwater in the Japan Trench, according to Professor Alan Jamieson, the expedition's chief scientist.

These slugfish, whose body has a gelatinous appearance, had only been observed at -7703 meters in 2008, according to the site of the Australian university.

Their size has not been specified but the species has already been recorded as reaching a length of nearly 11 centimeters.
