Looks like a paper clip and has a lifespan of up to 200 years, why has this squid evolved so strangely?

Perhaps this will be the strangest squid you have ever seen, because their appearance is like a paper clip.
What is the strangest animal you have ever seen? Maybe it’s a North American star-nosed mole with 21 tentacles on its tip and red like starfish, or a deep-sea Australian fish that, when brought to the surface, becomes strange shape like a pile of fat with a sad face.

The star-nosed mole is a species of small mole found in the humid lowlands of eastern Canada and the northeastern United States, with records along the Atlantic coast as far as extreme southeastern Georgia. It is the only member of the tribe Condylurini and the genus Condylura. Blobfish (also known as teardrop fish) – a fish voted by the Ugly Animal Preservation Society as the standard of evil. This fish was first found in the waters of New Zealand and Australia, at depths between 600 and 1,200 meters. These are also places where the pressure is about 118 times higher than sea level. If you’ve ever seen a cephalopod recently discovered by scientists, perhaps all the strange things in this world will become completely normal, and also not surprising. , because this creature is considered the strangest species. Essentially it looks like an oversized paper clip or a long “beard” on the head, they have a curved body with twists. This animal is called Diplomoceras maximum. It’s a pity that no matter in any zoo on the planet or on a deep-sea diving boat, you won’t be able to see this animal, because it is just like Tyrannosaurus. This animal lived in Antarctica during the Cretaceous period 68 million years ago and what we can see today are only their fossils. The age of the fossils is about 68 million years, the end of the Cretaceous period, the same time as the tyrannosaurs. This strange squid mainly inhabits the waters around present-day Antarctica. It is possible that they became extinct at the same time as the dinosaurs because of the catastrophic impact of the asteroid Chicxulub. The fossil of this strange squid was discovered by the Antarctic Expedition at the UK’s University of Leeds. Scientists conducted a scientific investigation on Seymour Island in the Antarctic peninsula for six years and discovered more than 6,000 fossils of marine life. The most special of these is the squid Diplomoceras maximum (Paperclip squid). Fossils of paperclip squid are now on public display at the Earth Museum in Ithaca, New York, if you’re lucky enough to see it, you won’t be able to imagine why this animal grew up like that. – it is about 1.5 meters long and can be up to 2 meters long, equivalent to the height of a human; if it stretched out its paperclip-shaped body in a straight line, its body length would exceed 4 meters. Their assumption is consistent because shells are known to grow by accretion, creating new growth each year. After shrinking the giant shells of these 1.5-meter-long animals, the researchers concluded that the only plausible explanation is that these animals have a lifespan of about 200 years. In addition, the most surprising thing to scientists is that this paperclip squid has a lifespan of up to 200 years, speculated now from the ridges on their shells, this calculation is similar to the way Calculate the age from the ridges of the tree trunk. Their shells were developed through accretion, based on repeated patterns of carbon and oxygen isotopes, which scientists believe reflects annual methane production on the seafloor. This means that the paperclip’s shell will grow one more groove each year, and it will grow longer and longer. And the question is why this squid was able to live so long, while modern cephalopods, such as cuttlefish and squid, have a lifespan of less than 5 years even when they are the largest species of this family or the cephalopods are also shellfish, they can only live up to 20 years. So paperclip ink can live to be 200 years old is completely strange and mysterious. New research published at an online meeting of the American Geological Society claims to have discovered new evidence for a previously unknown creature with a very long lifespan. To answer this question, paleontologists have put forward a threefold hypothesis – they suggest that their habitat at that time was similar to that of the Greenland shark, which lived in cold waters. The price of Antarctica, have long and dark winters, lack of food sources, so they have to slow down their metabolism to increase their chances of successful reproduction, so their lifespan is also increased.
