What is waste for humans is a treasure for squid. They “build” dwellings from it – Earth – Science and Technology

What is waste for humans is a treasure for squid. Even so, one could summarize the results of a group of scientists from Italy and Brazil who wanted to find out how squid react to garbage that ends up on the seabed.

For years, divers have been taking pictures and recordings of cephalopods around the world, hiding in empty bottles or carrying half of a discarded coconut shell on their heads. But scientists have not paid much attention to this phenomenon. Therefore, the scientific team has now decided to assemble 261 similar images – and find out what exactly squid do to human waste.

“These deep-sea records are extremely interesting because even at great depths, these creatures encounter garbage,” Maira Proietti of the Federal University in Rio Grande, Brazil, told the newspaper. The Guardian.

The primary way squid uses garbage is to create a home. Octopuses are home to glass bottles of all shapes, which are their primary choice; they are followed by plastic and finally metal containers.

Smaller pieces of garbage are also used in other ways. Objects such as metal and plastic lids or stoppers, pieces of glass and plastic, metal spoons and fragments of coconut shells serve as camouflage. Larger items, such as cans, plastic bags, and even a piece of surfboard, serve as a means of hiding among the stones.

Similar ingenuity proves the intelligence and extreme ability of cephalopods to adapt. The downside of research is the possibility that octopuses use human waste because the supply of available shells is shrinking. And some human garbage can be downright dangerous or harmful to them – like shards of glass or a car battery handled by one of the octopuses.
