} Study co-author Kobayashi also noted that H. gigas are opportunists. SOI/Stuart Piertney. With this in mind, researchers collected amphipods from three trenches, the Mariana Trench (the deepest point on Earth), Mussau Trench, and New Britain Trench… “There are species living in the deepest, most remote places on earth which have already ingested plastic before they are even known about by humankind.

In the deeps of the Mariana Trench lives a species of amphipods (Lysianassoidea amphipod) and marine biologists of Newcastle University, who study marine life in the trenches of the Pacific Ocean, wondered if plastic would be present in these amphipods. The trench bottom was home to an array of sea cucumbers, sea anemones, soft corals, jellyfish, comb jellyfish, giant amphipods, crinoids, crustaceans and fish. document.dispatchEvent(myEvent); Ultimately, the scientists found that the pollution was omnipresent and that it could be found in “in all samples across all species at all depths in both trenches.” if (captureOffScreen) { var spector; The specimens of Hirondellea gigas were collected in 2009 in the Mariana Trench's Challenger Deep, Earth's deepest point and the same location of National Geographic explorer and filmmaker James Cameron's record-breaking dive in March 2012. if (contextNames.indexOf(arguments[0]) !== -1) { University of Aberdeen marine biologist Alan Jamieson agreed that the amphipods are using the enzymes to feed on wood.

Lowered into the Challenger Deep trench for three hours, the traps caught almost 200 amphipods. Researchers have uncovered the presence of plastic in a previously unknown species of deep-sea amphipods, which was discovered in the Mariana Trench – the deepest trench in the world.
