Giant squids can see well in the deep, dark ocean. That is good for them because it helps them find their way around. But they are also sensitive to bright lights that scientists put on submersibles and cameras. They do not like the light so they go away when scientists come near with these things.

Despite their enormous size, these cephalopods are rarely sighted in the water; most sightings of behemoths have come from dead or dying squids that wash up on beaches or get caught in deep-sea trawling nets. That began to change in 2012 when a team of marine scientists tracked a juvenile A. due near Japan’s southern island of Kyushu.

According to the study’s authors (many of whom were in attendance for the giant squid sighting in the Gulf of Mexico in 2019), part of the creature’s elusiveness is due to its huge eyes.

Giant squids may live for thousands of feet beneath the ocean’s surface. Because of this, the colossal squid developed the world’s biggest eyes to help it adapt to the limited amount of light that reaches this deep. Each of these cephalopods’ peepers is about as big as a basketball — roughly three times the diameter of any other creature, according to Live Science.

Octopuses are found all over the world. They live in warm places and cold places too. Scientists have found them living on the sea floor in Antarctica.

They were not born there, though! If they lived on land, you would know what to call them because their name means ‘feet’. But octopuses do not have feet that can work on the land. So we just call them octopuses instead of something else that has eight legs and is ahead with lots of eyes.

In 2004 scientists from New Zealand went down to the Antarctic Ocean where they thought an octopus had been seen before. They did find one, but it was harder than usual to get a good look at it because it hid away quickly after seeing the divers.

Antarctic octopuses grow to be very big. Scientists think the one they saw must have been at least 100 years old!

Giant squid can be as long as a city bus, but the Antarctic species may even be bigger. In 2006 a deep-diving submersible explored a ridge 3,000 meters below sea level and spotted an octopus with arms about 1 meter in length. Researchers believe this species of octopus could grow up to 16 meters from arm tip to arm tip — that’s longer than two Humvee parked end-to-end!

Rivalry between octopuses and squid: The giant and colossal squid both live in colder waters than do smaller squids and octopuses. Only the biggest and strongest can survive in such harsh conditions. As a result, they tend to dominate their smaller neighbors. This has left them with little competition for food, which is why some scientists believe they might be able to grow so large.

This is just one of many theories about what makes giants — others suggest that cold water slows these cephalopods’ metabolism and allows them to live longer, allowing more time for growth (if there’s plenty of food around).

The largest known octopus was an Antarctic species caught by the crew of a New Zealand fishing boat on February 22, 1964; at 30 feet long (9 m), it weighed 1 ton (900 kg).

New OCTOPUS found in Antarctica – could be species new to science

Scientists have discovered a giant octopus, measuring at least 2.5 meters across – possibly the size of half an adult human being – called Giant Antarctic Octopus (Enter octopus dolphins), living near Antarctica during their first scientific voyage to the Ross Sea.

The life form is described as “a true octopus”, with eight arms and two longer tentacles for catching prey.

Octopuses are known around the world as ‘the thinking person’s craniates’ (animals with heads).

While many people think of them as loners, they’re actually very smart animals who can use tools; one scientist describes the octopus as a cross between an alien and a clam.

Their intelligence makes them tricky to study because they play tricks on scientists by taking apart their equipment if they don’t have cameras to monitor them around the clock.

In response, some researchers now carry video cameras with infrared lights that won’t attract the octopuses’ attention.

Octopuses, like this new species found in Antarctica, are known as ‘the thinking person’s craniates’ (animals with heads).

“They’re very smart,” said Peter Godfrey-Smith, a professor of history and philosophy of science at the University of Sydney who has studied octopus behavior. “They seem to show flexible learning capacities in some situations.”

In one experiment, an octopus was offered a choice between two identical jars from which it could choose to eat from either one. In another condition, one jar would be empty while the other had food inside. In both cases, when the octopus reached for the empty jar, instead of finding no food there as expected, the octopus would find food in the jar.

Researchers saw this happening several times and reasoned that it was because there was a visual cue on the outside of the jars suggesting it. So they think up an experiment to trick their animal: by painting black around the lids to block out any such clues, scientists found no evidence of octopuses successfully reaching for the empty jar anymore. The study suggests that octopuses can learn to use previous knowledge about situations and modify their behavior accordingly. They do not just rely on their sense of sight and smell alone but use sensory information from all over to understand what’s going on around them.

Octopuses also have keen spatial memory — they’re able to navigate mazes and remember where things are. They have a highly complex nervous system that’s very different from our own, but they also have roughly the same number of neurons that we do.

Octopus researcher Benny Hochner said, “I think it is this type of behavior which makes octopuses so special.”

The researchers are still trying to get DNA samples from the newly discovered creatures to ensure they are indeed a new species. According to Godfrey-Smith, there are about twelve known types of octopus in Antarctica, and some may turn out to be similar in appearance to Enter octopus dolphins. The team plans further expeditions and hopes their findings will help determine how much humans should disturb Antarctic sea life.

1. The octopus is a deep-sea creature
2. It was discovered by the crew of an Antarctic research vessel
3. The octopus is not like any other living there – it has no predators, and its blood does not contain hemoglobin
4. Scientists are still unsure why this particular species lives in such harsh conditions
5. This discovery could lead to new discoveries about life on Earth as well as how organisms survive in extreme environments
6. There’s nothing else quite like it!
