Biologists found creatures that spread plastic all over the ocean


Underwater inhabitants called appendicularia cleanse surface water of the oceans from plastic, however, contribute to the fact that this plastic gets deeper and begins to pose a threat to the animals living there. To such conclusion experts of the Research Institute aquarium Monterey Bay.

The authors of the study observed and conducted a series of experiments with the largest appendicularian, Bathochordaeus stygius.These animals surrounds the two filter representing a kind of “house” and catching flying by fragments of organic matter remaining from the other local inhabitants. External filter stops too large particles of potential food, and accumulate in the internal pieces, for its size ideal for powering marine life.

When the filters are too “clogged”, appendicularia throw them away, and after a while grow a new one. “Abandoned houses” together with all that they are stuck in this sink to the ocean floor and become a food source for its inhabitants. It is assumed that appendicularia play a very important role in ensuring that creatures living on a greater depth, nutrition.

The more the world’s oceans is polluted by plastic, the more its particles falls into the “house” of marine animals, and then, being in even greater depth, and poison those who live there. It is about how the plastic fragments getting stuck in filiro, and those that Bathochordaeus stygius absorb and then regurgitate pellets.

According to experts, these data help to answer the question of why the surface of water, which constantly gets large amounts of plastic, today are less polluted than “should be”. Apparently, the animals simply filter contribute to the fact that the fragments of plastic quite quickly find themselves in deeper.
