Chinese scientists discover 'seabed gardens' in Mariana Trench

In the real time videos that the ROV transmitted back, scientists observed a seabed garden with a lot of corals, sponges and brittle stars at a depth of 880 meters at first and found more in the following exploration.

"The seamount under investigation is located in an oligotrophic sea area at 10 degrees north latitude," said Xu Kuidong, chief scientist aboard the vessel and a researcher with the Chinese Academy of Science. "It is very rare to see such multi-colored coral forests there."
