About Pseudoliparis swirei

The Mariana snailfish or Mariana hadal snailfish Pseudoliparis swirei is a species of snailfish found in the Mariana Trench in the western Pacific Ocean. It is known from a depth range of 6,198–8,076 m，which is possibly the record for a fish caught on the seafloor. Various anatomical, physiological, molecular and genetic adaptions help this species survive in such depths. It is abundant in their deep-sea habitat and has several unusual adaptions for its dark and high pressure habitat, including transparent skin that lacks pigment, certain organs and eggs that are enlarged, the muscles are thinner, the ossification of its bones (notably the skull) is incomplete.
