The theoretical maximum depth for fish is at about 8,000–8,500 m (26,200–27,900 ft), beyond which they would become hyperosmotic. [ 22 ] [ 23 ] [ 24 ] Invertebrates such as sea cucumbers , some of which potentially could be mistaken for flatfish, have been confirmed at depths of 10,000 m (33,000 ft) and more.
Remotely Operated Vehicle KAIKO reached the deepest area of the Mariana Trench and made the deepest diving record of 10,911 m (35,797 ft; 5,966 fathoms) on 24 March 1995. [16] During surveys carried out between 1997 and 2001, a spot was found along the Mariana Trench that had a depth similar to the Challenger Deep, possibly even deeper.
The study concludes that with the best of 2010 multibeam echosounder technologies after the analysis a depth uncertainty of ±25 m (82 ft) (95% confidence level) on 9 degrees of freedom and a positional uncertainty of ±20 to 25 m (66 to 82 ft) remain and the location of the deepest depth recorded in the 2010 mapping is 10,984 m (36,037 ft) at
Researchers believe they've recorded potentially the first-ever sighting of an adult abyssal fish, Melanocetus johnsonii, in broad daylight. Normally found at depths between 200 and 2,000 meters ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]

Because of the high pressure, the depth to which a diver can descend without special equipment is limited. The deepest recorded descent made by a freediver is 253 m (830 ft) as of 2012. [22] The scuba record is 318 m (1,043 ft) as of June 2005, [23] and 534 metres (1,752 ft) on surface supply on the Comex Hydra 8 experimental dives in 1988. [24]
