Animals Living in the Mariana Trench

The Mariana Trench is the deepest location in the entire ocean. If one were to reach the bottom, they would be crushed by an atmospheric pressure of 1086 bar!!!

Naturally, this inhospitable environment is home to few creatures. These primarily include some fish and invertebrates. The animals living at these depths have to contend with a lack of food and light. Several invertebrates consume hydrogen and methane from the environment, while fish like anglerfish and viperfish species generate light to both see as well as attract prey.

Animals living at these depths are known for their bizarre appearances. The Mariana Trench is home to oddities like the goblin shark, the dumbo octopus, and the ping-pong sponge tree.

The goblin shark and various species of anglerfish, fangtooths, and hatchetfish.
