However, there is not a lot known about the mysterious giant squid, a creature that, for the first time, it was captured on film in 2005. Now, researchers have decoded the giant cephalopod in the human genome, hoping to unlock more of the secrets of the legendary octopus.

The study, which was published in the Giga Science, and points out that the giant squid has a giant genome, with approximately 2.7 billion DNA base pairs. By way of comparison, the human being has about 3 billion DNA base pairs. Caroline Albertin, one of the study’s co-authors have found that the Hox and Wnt developmental genes that are seen in nearly all animals, are also present in the giant squid genome, which means that it’s huge in size, it is not caused by the whole-genome duplication.

“In terms of their genes, and we found the giant squid looks much like any other animal,” Albertin said in a statement. “It means that we are looking at, this is truly a bizarre animal in order to learn more about ourselves as well.”

The analyst also discovered more than 100 genes of the protocadherin family, “most of the time is not to be found in the abundance of aquatic animals that can be seen in the giant squid genome.

“Protocadherins are believed to be an important role in the wiring of a complex brain to understand,” she added. “They were supposed to have been an important innovation, so we were really surprised when we discovered that more than 100 of them in the cuttlefish genome, (2015). That seemed to me to be a smoking gun, how can you have a very complicated mind. And we have seen a similar expansion of the protocadherins in the giant squid, as well.”

In 2015, Albertin, who led a team that was the first genome of a cephalopod.

As such, there is still more work to be done in order to understand how the giant squid was solid, Albertin added.

“A genome is a first step in answering a lot of questions about the biology of the very strange animals,” Albertin noted, including features such as the largest brains among the vertebrates, their behavior, and the ability to instantly camouflage itself.

Albertin said that the cephalopods are thought to be independent of each other and have evolved in the vertebrates, in spite of the fact that a lot of the more complex and advanced features. “By comparing their genomes we may be asking,” Are cephalopods, and vertebrates in the same way it was built or are they built differently?'”

“The giant squid genome, and is an important input in helping us to understand what makes a cephalopod a cephalopod,” she concluded. “And it can also help us to understand how new genes emerge in the evolution, and development.”

The largest giant squid ever recorded was almost 43 feet long and probably weighed close to 2,000 pounds, depending on which of the Smithsonian.

In June of 2019, NOAA, and saw a giant squid in U.S. waters for the first time, as part of the rare images in which biologists describe as “the most amazing video you’ve ever seen.” The giant cephalopod was seen, at about 100 km to the south-east of New Orleans, La.


Quite elusive, the giant squid has been associated with myth since ancient times. The Charlotte Observer, citing data from The National Museum of Natural History, the ancient mariners mistakenly believed giant squids were mermaids, and other mythical creatures.

“For a long time, people saw mysterious movements in the water, or of death, found the giant squid and didn’t know what they were, and even be mistaken for a giant squid skeleton of a merman or a mermaid,” the museum said on its website.

In August of 2018, a 14-foot squid washed up on the shores of Wellington, New Zealand, in which the images of the massive cephalopod to go viral.
