Psychrolutes marcidus, commonly known as the blobfish, inhabits deep-sea environments off the coasts of Australia and Tasmania. It is renowned for its gelatinous, blob-like appearance when brought to the surface due to a lack of skeletal structure. This unique adaptation allows it to withstand extreme pressure at depths of up to 1200 meters.

Psychrolutes marcidus, commonly known as the blobfish, is native to the deep waters off the coasts of mainland Australia, Tasmania, and New Zealand. It is predominantly found in the deep-sea regions of the southwestern Pacific Ocean.

The blobfish inhabits the deep-sea environment, typically at depths ranging from 600 to 1200 meters (2000 to 3900 feet). The conditions in these depths are characterized by high pressure, low light, and cold temperatures, often near freezing.

The blobfish occupies a benthic niche, living on or near the ocean floor. It is adapted to a life of low energy expenditure due to the scarcity of food resources in its environment. The blobfish's gelatinous body structure is suited to withstanding the high pressure of the deep sea. It primarily feeds on small crustaceans and other invertebrates that drift into its vicinity.
