Pseudoliparis swirei is a species of snailfish in the family Liparidae, discovered in the hadal zone of the Mariana Trench at depths exceeding 7,000 meters. This species is adapted to extreme deep-sea environments, thriving under immense pressure and near-freezing temperatures. Pseudoliparis swirei is characterized by its gelatinous body and reduced skeletal structure, which help it withstand the crushing pressures of the deep ocean. Its discovery provides valuable insights into the adaptations of vertebrates to one of the most extreme habitats on Earth.
