North Pacific Giant Octopus

North Pacific Giant Octopus – Enteroctopus dofleini

Description

The winner of being the largest of all Octopus species in the world is the North Pacific Giant. This one can be close to 150 pounds when it is fully mature and be as long as 15 feet. When you consider that some species are only a few inches in length and weight a couple of ounces there is a huge difference. The overall size of these octopuses really depends on the location where they live and what they feed on there.

You may read stories out there about some being much bigger than that. While those stories do continue to circulate they haven’t been verified. However, many experts don’t doubt at all that they can grow to be quite a bit larger than what we have recorded. Since they can blend into their surroundings so easily it can be very easy to miss one when it is right in front of you.

The ability to change colors due to pigmentation is very easy for this particular species. Since they can’t move as quickly or fit into small crevices they use the changing of color to blend in and to avoid being detected. They are normally a shade of red or brown and they can be light or dark. Yet due to their many habitats, they can be just about any color.

Anatomy

The anatomy of a North Pacific Giant Octopus is very interesting. They tend to lie flat often on the bottom of the ocean so they seem to be like a tan starfish. It is this blending in though that makes them able to avoid detection from various types of predators. They have very long arms that are also thick. Along the length of them are many suction cups.

They have a head that is quite large compared to other species of Octopus. They have a mantle part of the body that is spherical in design. This is part of what helps them to be able to move around effortlessly.

Evolution

No one really know for sure what has occurred throughout time for the North Pacific Giant Octopus to take on the role that it has. There is only speculation about how they have changed from millions of years ago until the present. It is strongly believed though that they have been able to continually adapt to their changing environment. The development of so many arms may be directly linked to the evolution process for them.

Behavior

We don’t have very much information at all about the North Pacific Giant Octopus when it comes to their behavior. What we do know about them is that they have the ability to learn new things all the time. They can adapt to a changing environment through their learning skills. They are able to solve problems and they have excellent memories.

They do seem to spook easily and since they can’t move as fast as other species of Octopus they will release ink to getaway. They seem to do this more often than other species of Octopus and they also produce a larger volume of the dark ink because they have bigger glands for the production of it.

Habitat/Distribution

The North Pacific Ocean is home to this species of Octopus. They tend to live about 200 feet below the surface of the water. Yet they have been found to live deeper and that is believed to be due to the changes in their environment. When they don’t have enough food to eat or they can’t find shelter then they will move deeper in order to have those basic needs met.

Diet/Feeding Habits

They spend most of their nighttime hours looking for food. The drawback of being a larger species is that you have to eat more to have energy. There is usually no problem though for the North Pacific Giant Octopus to find more than enough to eat in their natural environment. Some of their common items include fish, crabs, clams, and shrimp.

You may find it hard to believe but they have also been known to consume some of the small species of sharks out there. This can offer them a great meal and one that means they don’t have to hunt anymore for a day or two. They are opportunistic so they will do what they can to benefit as those chances for great meals happen to come their way.

The fact that they can consume these sharks has been verified through the stomach contents of some that have been captured in nets or killed accidentally. Without that type of information to verify it though this would continue to be considered a myth. The fact that they can consume small sharks really shows us how powerful the North Pacific Giant Octopus can be.

Reproduction

Mating is about the only time that the male and female North Pacific Giant Octopus come into contact with each other. The process of mating involves the male taking a sperm sac from his body and placing it into the mantle of the female. This sac has a very thick protective coating on it because she may carry it around for about six months before her eggs are ready to be deposited.

There is also lots of sperm in that sac because she will need to allocate it among approximately 100,000 eggs. That process can take her many weeks to complete and it will consume every bit of her time. The role at that time switches from her own needs to protect the eggs at any cost. She will do all she can to keep them clean and to keep predators at bay.

Around the same time that her eggs hatch she will be at the end of her life span. For the males, they will die very soon after mating. The life span is prolonged for the female to give her time to pass on survival to the next generation. Even in the best of conditions this species of Octopus doesn’t live more than 3-5 years. Yet that is considerably longer than many species with a life span of less than one year.

These offspring are extremely small at birth but have the ability to swim and to be able to find food. Yet they are also highly regarded as a source of food by predators out there. Out of those 100,000 eggs, only about 1,000 of them will survive the first few months of life. Even less than that will reach the age of maturity.

Predators

Even though this is a large-sized Octopus that doesn’t make it exempt from predators. In fact, there are some large ones out there that find it to make a very nice meal. Among them include Sperm Whales, Sea Otters, and Harbor Seals. It really depends on the location where the happen to live.

Humans do find capturing them to be ideal due to their size. They can offer quite a large amount of meat to be used for various types of food dishes. They also like to get rid of these creatures in the water because they consume many of the other creatures that they are trying to commercially harvest. Even so, there doesn’t seem to be a problem when it comes to their overall numbers remaining out there.

Octopus Habitat

Octopus Habitat and Distribution

The Octopus of different species lives in every ocean of the world. They only live in saltwater. They are very adaptable and live in everything from small swallow pool to depth up to  2,000 m (6,600 ft).
The most common area of the ocean for them to reside happens to be along the coral reefs and ocean floor. They create dens where they live and can be undetected in the water. They will also find small crevices and hide under rocks.

If you are in the water looking for Octopus you have to know where to look and what to pay attention to. They are able to blend into their surroundings so well that even a well-trained eye may overlook one of them if they aren’t’ careful. Even when researchers do find where Octopus live it is only for a small period of time.

Three hearts, a massive brain, and blue blood, they navigate unlike anything else. The earliest octopus fossil is Pohlsepia, which swam the oceans 296 million years ago.

They Don’t Get Too Comfortable In Any One Place

They tend to find a new location every 10 to 14 days. Some of them even live in bottles or other rubbish that has found its way to the bottom of the floor in the ocean. They are very opportunistic when it comes to finding a place for them to call home for a period of time.

They are able to live in different temperatures of water. What is very interesting is that the species living in warmer bodies of water are much smaller than those that reside where it is colder. The fact that they can be so adaptable to different areas of the water is one of the reasons that the various species have been able to survive for millions of years.

It is a common belief that all Octopus live at the bottom of the ocean. While the majority of the species do, some of them also live very close to the surface. With most species, the young offspring do live at the surface of the water when they first emerge from their shells. This makes them very vulnerable to the different predators out there. As they get older they will move further down in the water.

Where do octopuses live?

Big Octopus in their natural habitat

There aren’t many areas of the ocean where various types of Octopus don’t reside though. Finding them can be exciting for researchers. Snorkeling is a common adventure for vacationers around the oceans. If you do take part in it try to find squid in the various areas. You will be very amazed seeing them in their natural habitat.

Octopuses Are Very Sensitive To Toxin

Due to pollution, the natural habitat of the Octopus continues to be put at risk. They can’t live well in areas where there are lots of toxins. They have a hard time finding enough food in those locations. It can also be unsafe for the females to lay their eggs in such a region. Sometimes the efforts of humans result in the Octopus having to relocate if they are going to be able to survive.

These animals don’t do very well in captivity at all. They already have a very short life span. Being in captivity can create nervous system problems for them as well as so much stress they won’t eat. Some people do try to keep them as pets in aquariums but it very seldom works for very long. They can also take the lids off and escape, which can occur even when a great design is in place. They are well known for their ability to escape.

Even though researchers know lots about the natural habitat of the Octopus and do their best to recreate it for a great setting, being able to observe them in a captive state is extremely difficult. The new setting alters their behaviors too much for them to be credible.

Anatomy Invertebrates = No Bones

The body of the Blue-Ringed Octopus is very impressive. They are very small in size but their anatomy allows them to be very powerful. The body is very flexible due to the fact that they don’t have a skeleton. They are able to move very quickly through the water as well. The body is very small with an overall length of about 8 inches. However, the arms can spread very wide when they are trying to capture prey.

They are usually seen swimming in the water instead of crawling. They do lay sideways though which is why it is so easy for someone to end up stepping on them in the water. What is unique is that such a small creature can have such a powerful amount of venom in their bodies. It is a huge mystery when it comes to the design of their anatomy.

Evolution

There are experts out there with an explanation for that though. They believe that this powerful venom is the result of evolution. It has made it a powerful source to be reckoned with in the water. They believe that the venom has only continued to get stronger over time.

Evolution is a huge issue with any animal, it is a way to see where they once were and how that has allowed them to be shaped today. Yet there isn’t very much to know about the Blue-Ringed Octopus. It is really a mystery about how they came to be about. They have a body that is very different from other types of creatures that live in the water.

They have proven high levels of intelligence as well as the ability to adapt to their environment. It is believed that the ink sac they have is one part of evolution. It offers the Octopus a way of escaping predators so that they can survive.

Anatomy Of The Octopus – Read Or Listen To The Article Click Here.

Behavior

This is one of the most aggressive species of Octopus in the world. They aren’t as likely to run and hide as they normally would. They also will fight with other Octopus in the area to be able to keep their food and shelter to themselves. With most other species they simply ignore each other but that isn’t the case here.

The venom that the Blue-Ringed Octopus is able to release is a huge concern for humans. In fact, it is the only type that is able to kill human if they get bitten by one of these octopuses. That is a prime reason why many people avoid bodies of water where they happen to live. They worry about stepping on one and it biting in retaliation.

How can I see If The Blue Ringed Octopus is aggressive?

Answer: It will give you a fair warning by Flashing Bright Blue Rings.

Where do I find the Blue Ringed Octopus? – Habitat/Distribution

Indian and Pacific Oceans (Shallow waters) are the Blue-ringed octopuses habitats.
This type of Octopus isn’t as widely distributed out there as many others. They are known to reside in certain areas of the Pacific Ocean. The largest groups are in the waters around Japan and Australia. Determining the exact locations of them there can be difficult as they move often. They continue to find new homes every couple of weeks for safety.

Diet/Feeding Habits

They generally are able to find plenty to eat due to the diverse nature of their diet. They hunt at night and thanks to their excellent vision they are able to find food with no trouble at all. They consume shrimp, fish, and hermit crabs. They are successful hunters due to their speed. They are able to place venom into the body of their prey in very little time.

This process is one that completely paralyzes the prey. This gives the Blue-Ringed Octopus plenty of time to come in and to use its powerful beak to break the shells. Then it can consume the food source inside of it. They are also known for their cannibal behaviors. Yet it is important to point out that they consume each other for territorial rights and not due to the urge to find food.

Octopus Reproduction Read Or Listen To The Article Click Here.

Reproduction

As I mentioned they are very isolated due to the aggressive nature they portray. They do change that tune though when they are ready to take part in mating. The males and females will stay in the same area for a couple of days in order to for the mating to occur as many times as possible during that period of time.

The males love the act of mating, and so the females have to push them away after a couple of days. They will be persistent which can result in some bitter battles taking place. The females are ready by then to be left alone and they will do whatever they have to in order to get that message conveyed to the male.

Once they are done with the mating process they will go their separate ways. The females will have about 50 eggs that develop in their bodies. They will fertilize them with the sperm they gathered from the male. Once she has successfully done that she will place them securely under her arms. The suctioning power will keep them in place until they are ready to hatch.

Both the males and the females have a very short life span. The males will die soon after mating is finished. This can be within a couple of days or they may have a few weeks of life left. For the females, once she has those eggs to care for her own needs are no longer a priority. She will begin shutting down too with her death being very close to the hatching of her eggs. The average life span for this Octopus is 1 ½ year.

Octopus Predators – Read Or Listen To The Article Click Here.

Predators

There are quite a few different predators out there that the Blue – Ringed Octopus has to deal with. They include whales, eels, and birds. These types of predators are able to get to them very quickly and with the element of surprise on their side. There are times though when these predators become the prey due to the Octopus getting a good bite. That will immobilize them. The Octopus can either feed or it can swim away.

Due to the very danger of these octopuses, they are also heavily hunted by humans. They figure it is best to get rid of them from the water than to live in fear of them. Most people don’t seem to think there is anything wrong with hunting them so that people can be safer in the water.
