Why do Sea creatures Eat Plastic?
Why do Sea creatures Eat Plastic? – In a recent interview about Blue Planet II, David Attenborough described a scene in which an albatross comes in the nest to feed his children.
They said, “Do you know what came out of his mouth? No fish, and no squid-they eat most, rather than plastic out of their mouth.”
Attenborough says that it was a bit of a hurting heart and also very strange. Albatros travels several thousand kilometers long for his favorite prey. He takes his prey with water very easily.
In such a situation, it is not understandable to become so stupid as a wise bird and to bring the plastic in the mouth after making such a long journey for hunting.
The comfort is that Albatross is not alone in those who do this. From small creatures to large whales to about 180 species of sea creatures are eating plastic.
Even plastic is found in those fish that we eat everyday. Not only this, plastic is also found inside our favorite lobsters and mussels.
Why do animals like plastic?
In essence, every size-type creature is eating plastic and in a year 12.7 million tonnes of garbage is found in the sea, the situation is becoming more worrisome.
Due to the abundance of plastic in the ocean, sea creatures are eating wildly in this way. For example, Zooplanktons only eat small particles of plastic in water because they can eat particles up to a particular size.
Canadian Institute of Ocean Science plankton ecologist Moira Gaill Breath says that “if any particle of plastic fits in size, then it is their food.”
Just like Zooplanktons creatures, cylinders called ‘Cucumber’ do not worry much about what they are eating. Crawling on the sea floor, they scatter the silt and find their food. It has been learned from an analysis that these living beasts in the ocean floor can eat 138 times more plastic than the required amount.
Compared to normal food, it is easy to catch the particles of plastic with their tangents, because these particles are large and easy to catch, but the rest of the species are not forced to consume plastic.
Many creatures are eating plastic from their own means. To know why the animals are so liked by the animals, we need to know how they see the world.
Matthew Savoca of California’s NOAA Southwest Fisheries Science Center says, “Experience and sensing of animals is very different from us. In some situations, it is better than us, some are bad but it is definitely different from us. ”
One argument is given that animals sometimes accidentally eat the plastic. Since he looks like a well-known food item, they gets confused. For example, they look like delicious fish in order to see plastic pallets.
Most sea creatures, including albatross, mainly depend on the power of their snoring while looking for food. Savoca and his colleagues used an experiment to find out that some species of fish and sea birds are attracted to the smell of plastic.
He specifically told about ‘dimethyl sulphide’ (DMS). It is a substance that attracts hunting birds and is probably the same chemical that comes out of plastic.
Actually the ‘Algi’ grows on the floating plastic, when this ‘algi’ is crab, which is a big source of seafood, then DMS gets out of it.
As a result, the birds and fish that actually eat the crials, they are attracted to this DMS and consume plastic.
If we talk about the ability to see, then it is also related to the extent of eating plastic plants of marine organisms. Like humans, sea turtles depend on your ability to look for food. Although it is believed that they have the unique ability to watch the UV light, which makes their visibility different from us.
Camer Schweler of the University of Queensland of Australia has tried to understand their ability to see the sea turtle, while trying to figure out what these turtles look like in this plastic. He also inspected the stomach of dead turtles so that it can be ascertained which is the plastic of his choice.
From research he came to the conclusion that at the age when small turtles consumed any type of plastic, the old age turtles prefer soft and transparent plastic.
Schweiler believes that his research proves that turtle mistakes the plastic bags as a tasty jellyfish.
Its color also has the importance of plastic consumption. Schwelmer and his colleagues found that young age turtles prefer white plastic, while ‘shirer’ likes red plastic.
Hunting Based on Eco-location
Apart from sight and smell, there are many other senses which are used to find organisms. Many sea creatures prey on the basis of ‘Eco-location’, especially the teeth of whales and dolphins.
‘Eco-location’ is considered a very sensitive factor, but despite its dozens of sperm whales and teeth whitening.
