1) The deepest dwelling vertebrates on Earth, snailfish have been discovered in ocean trenches in other parts of the Pacific.

2) This new species of snailfish was discovered 7 kilometres down in the Peru-Chile trench in the south-east Pacific Ocean using a deep-sea baited camera system.

3) Living so far underwater, the newfound, 6-inch-long (15-centimeter-long) snailfish can withstand pressures equal to 1, 600 elephants standing on the roof of a Mini Cooper, according to Oceanlab.

4) The Peru-Chile trench hadn't been examined before at such depths, Priede said, which inspired expedition leader Jamieson and colleagues to hunt there for snailfish.

5) "But instead he seems to have photographed yet another different species" of snailfish, among other finds.

6) The deepest known fish, found at 4.8 miles (7.7 kilometers), are snailfish filmed in the Japan trench in 2008.
