Jiaolong obtained three two different species of sea cucumbers, a starfish, a willow coral, two benthic giant protozoa, three species of sponges (one each), a sea lily and other marine biological samples, as well as six tubes of PUSHCORE (columnar) sediment, five basalt samples and dozens of polymetallic nodules, and photographed rat tail fish, blind fish, hydroids, ear octopus, anemones, armored shrimp and other rich macrobiotic populations on video.
The Jiaolong is a manned submersible designed and developed by China itself, and is also a major research project under the 863 program. from May to July 2010, the Jiaolong conducted several dives in the South China Sea, with a maximum depth of 3,759 meters.
In 2002, China's Ministry of Science and Technology listed the development of deep-sea manned submersibles as a major special project of the National High-Tech Research and Development Program (863 Program), and initiated the self-designed, self-integrated development of the Jiaolong manned deep submersible, which, from 2009 to 2012, "successively" achieved 1,000-meter, 3,000-meter, and 3,000-meter dives. From 2009 to 2012, "Jiaolong" successively achieved the success of 1000m, 3000m, 5000m and 7000m sea trials, and in June 2012, it set a record of 7,062m dive in the Mariana Trench, which is also the record of the largest dive depth of the world's similar operational submersibles.

[3]?On May 22, 2016, he successfully completed the last scientific dive in the Yap Trench, with a maximum depth of 6,579 meters. [4]?On March 8, 2017, the State Oceanic Administration was informed that on March 4 and 7, local time, the manned submersible Jiaolong conducted the third and fourth dives of the first leg of China's Oceanic 38 Voyage in the hydrothermal area of the Northwest Indian Ocean, Wolosi No. 1, and in the hydrothermal area of the Dashan, respectively. Both dives found hydrothermal vents in the investigation area and obtained sulfide samples.On May 23, 2017, Jiaolong completed the world's deepest dive, the diver stayed underwater for nearly 9 hours, the seafloor operation time of 3 hours and 11 minutes, and the maximum dive depth of 4,811 m. The dive was conducted in the first section of the first voyage of the 38th China Oceanic Voyage, the third and fourth dives.
