An underwater voyage, into the Mariana Trench, has found an unidentified species of fish more than 5 miles deep, which is a new record for the deepest fish ever discovered and filmed.
The Mariana Trench is the deepest point on Earth, which is located in the Western Pacific near Guam. It is made up of some of the oldest seabed in the world — over 180 million years old. It was formed by lava from underwater volcanic action. As lava cooled, aged and spread it became increasingly dense and settled. Many attempts have been made to reach to its deepest point, the Challenger Deep. According to the National Oceanic and Atmospheric Association, the water pressure at this deepest part of the trench is equivalent to the collective weight of 50 jumbo jets.
Marine biologists and scientists recently descended towards the Mariana Trench that gave up a creature living in this deepest point on Earth – a snail-fish. The discovery was made during a marine voyage on board the research vessel Falkor of the Schmidt Ocean Institute.
This Hadal Ecosystem Studies (HADES) expedition was led by co-chief scientists Jeff Drazen and Patty Fryer of the University of Hawaii. The researchers sent five deep sea vehicle systems called the Hadal landers for a total of 92 times at specifically targeted depths from 5000 meters to 10,600 meters. The Hadal lander is equipped with a variety of scientific instruments, high resolution cameras and array of small baited funnel traps, which are used to lure and trap small animals.
