  • Extends down nearly 7 miles

  • Located just east of the Mariana Islands
  • East of Japan
  • East of the Phillipine Sea
  • North of New Guinea

  • The Mariana Trench Marine National Monument (est. 2009), covering 95,216 square miles of submerged lands, is one of the largest marine protected areas in the world.
  • On *date*, James Cameron dove down into the Mariana Trench in a submarine, to study its diverse organisms
    • It took him 2 hours and 36 minutes to hit the bottom on his way down, and 1 hour and 10 minutes to break the surface on his way back up.

Biology in the Mariana Trench

    • The microorganisms living at this depth are immune to heavy metals that are toxic to other organisms; this could lead to biomedical breakthroughs if scientists can discover how these microorganisms resist the metals.
    • These microorganisms can also feed on methane and various oils.

    • Single-celled organisms
    • Many nuclei, but one cell
    • Up to 4 inches in length
    • They consume food by surrounding and absorbing it

  • FISH
  • Snailfish
    • Currently hold the record as deepest living fish ever photographed
    • It was filmed 4.8 miles below the surface

  • Amphipods
    • Related to shrimp
    • They will eat almost anything, including each other

    • It's hard for them to grow shells because of the water pressure deep in the trench
    • Snails with soft shells have been discovered in the trench
