This pale, tadpole-like fish reaches up to 28.8 cm (11.3 in) in standard length and 160 g (0.35 lb) in weight. [8] It is apparently the top predator along certain stretches of the Mariana Trench, feeding on tiny crustaceans in a deep-water habitat with few larger predators. [4]
Pseudoliparis belyaevi has been found in the NW Pacific Ocean in the Izu-Ogasawara and Japan Trench. [3] They were caught as deep as 7579m in the Japan Trench. [4] This possibly breaks the depth record for a fish collected from the seafloor, previously held by Pseudoliparis swirei at a depth of 7,966 m (26,135 ft). [5]
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
Pseudoliparis swirei: the Mariana snailfish, or Mariana hadal snailfish, is a species of snailfish found at hadal depths in the Mariana Trench in the western Pacific Ocean. It is known from a depth range of 6,198–8,076 m (20,335–26,496 ft), including a capture at 7,966 m (26,135 ft), which is possibly the record for a fish caught on the ...
Research has found an abundance of particulate organic matter (POM) within various hadal zone environments, such as the Mariana Trench and Atacama Trench. POM has been found both in the water column and sediments of the Mariana Trench. [5] Measurements taken in sediments at the deepest depths of the Mariana Trench show higher amounts of organic ...
The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches.The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level, and exists in long, narrow, topographic V-shaped depressions.
The Philippine archipelago, Ryukyu Islands, and the Marianas are examples. Another prominent feature of the Philippine Sea is the presence of deep sea trenches, among them the Philippine Trench and the Mariana Trench, containing the deepest point on the planet.
