Caribbean Reef Octopus

Caribbean Reef Octopus – Octopus briareus

Description

The Caribbean Reef Octopus is one that has a fascinating look to it. The combination of blue and green color is something that gets people’s attention. There can be brown on them too which ranges in shades of color. This is their coloring though when they are in their normal state. They are able to change the pigment of their body with ease. This serves as a type protection for them from predators.

They are often mistaken for Common Octopus species. One way to definitely tell them apart is by looking at the eyes. The Caribbean Reef Octopus has very dark circles of color around them. The body is about 5 inches in length but the span of the arms is quite a bit more. This can cover the space of about 23 inches. The overall size of them really depends on the particular region where they happen to live.

Anatomy

This is a medium sized type of Octopus, with an overall weight of just over three pounds. They have a head that is very large which is part of their mantle. The eight arms are extremely thick. They aren’t able to move as quickly as other species of Octopus but they don’t have to. Their abilities to lie flat allow them to appear like part of the natural scenery instead of a living creature. The body is often arranged in a pattern that looks like a parachute that is open and lying on the ground.

Evolution

While there are several theories about the evolution process for the Corral Reef Octopus there really isn’t any concrete evidence. It is believed that the Octopus has been on Earth for millions of years. Finding fossilized remains though is extremely difficult. We really have nothing to compare them to now versus early species.

Hopefully we will one day develop the right technology to allow that to happen. In the mean time though it can be fun to explore the possibilities. One of them is that the Octopus used to crawl around on the bottom of the ocean with two legs. The development of the additional legs helped it to use its senses for survival.

Behavior

Like all Octopus they live on their own out there. They don’t seem to be too bothered though when other types of Octopus come into contact with them. The passage is often something that occurs without any interaction at all. The only time they will pay any real attention to others around them is when they are interested in mating.

While all types of Octopus are very intelligent, this specific species is said to be among the most intelligent of them all. Extensive research though is almost impossible on them. This is because of the fact that they don’t live very long lives. It is believed that their intelligence would continue to develop and to improve though if they lived longer.

Habitat/Distribution

This is one type of Octopus that has quite a large dispersement out there. They are found around the Bahamas, and of course the Caribbean where their name comes from. They are well known in the Atlantic Ocean, especially around the Western region of it. They love to reside in sea grass and along the corral reefs out there. They do glow at nigh under lighting due to their coloring.

Generally you will only find the Caribbean Reef Octopus out there in areas where they can be in warm water. They will move around from one location to another, never staying for more than a couple of weeks in any one set location. The females that have laid eggs are easy to notice though. They will continue to hover over a given area until they die or their eggs hatch.

Diet/Feeding Habits

The Caribbean Reef Octopus spends most of its night looking for food. They majority of the diet is made up of crustaceans. They will capture them in the webbing of their arms, bite to release venom, and then the paralyzed critter won’t have any way to survive against it as the beak breaks the shell and eats what is inside of it. Various types of small fish are also known to be part of their diet as well.

Reproduction

Since this species of Octopus doesn’t live for very long, they are able to mate when they are from 3 to 4 months of age. The males seem to mature sooner than the females. The males will die sooner than the males as their role in mating is done once they have successfully released the sperm sac from their body to that of the female.

The males will actually fight with each other for the right to be able to mate with a given female. They would likely not be so eager to do so though if they knew that they would die. This fighting though is nature’s way of ensuring that the best genetic materials are able to be passed on to the future generations of offspring.

Even though the male is able to win that battle, he is far from done fighting. The female may not want to mate with him at all. If she doesn’t and he continues to pursue him she may bite off body parts or kill him. Yet the desire to mate is very instinctive for the males so they will continue to pursue a female. She generally will take part in mating as long as her basic needs are being met.

The female will die after mating too but she has one more aspect of life left to complete. Her mission at that point in time is to make sure as many of her eggs are able to be fertilized by the sperm and to hatch. There can be as many as 500 eggs that she will release from her body. She will lay them in either January or February. The warmer the water temperature is the sooner she will release them.

The incubation period will also be affected by the water. When it is warm the may only have 50 days or so before they hatch. In cooler temperatures it can be as long as 80 days though. The young offspring are amazing – able to move quickly through the water and to instinctively find food. They have a very quick growth rate too due to the whirlwind life span for them.

Predators

Depending on the location where the Caribbean Reef Octopus lives, it can have some concerns with various types of predators. Among them include eels, stingrays, small species of sharks, and various types of fish. They do put up a very good fight against these types of predators. If they can’t run then they will release ink from their bodies to confuse the predators.

This is one species of Octopus that humans continually hunt as well. They are considered to be great for various types of meals. You can buy them to cook on your own or you can eat at certain restaurants that offer them on the menu. They aren’t in any jeopardy though of being extinct as there is more than enough of them out there that live in the wild.

What is the mimic octopus? Description

The name for the Mimic Octopus comes from the fact that they often copy the behaviors of other types of animals in the water. They do this in order to trick predators into leaving them alone.

They aren’t very large Octopus with an overall length of two feet when they are fully grown. They have a normal coloring that spans many spans of brown and white. They also have stripes and spots on them that help to blend into surroundings. Like other types of Octopus, they can change the colors of their bodies to blend in when they need to. The changes in their environment are what will trigger those changes.


Where are the Mimic Octopus distributed?

The Mimic Octopus is found in the area of South East Asia. Along the coast of Sulawesi is where most of them are located. This is a fairly new type of species that was identified in 1998. It is believed that there could be other habitat locations for them that simply haven’t been found yet. They seem to prefer warmer waters and muddy locations out there.

Behavior

The Mimic Octopus is fascinating to watch due to the fact that they do act like many other animals. For example, they may move along in the water mimicking the movements of an eel. They have been observed mimicking plenty of other animals too though including stingrays, jellyfish, and starfish. Not only do they copy the movements but they also turn their bodies to those colors so that they will fit the description well.

They are extremely intelligent and researchers believe they choose an animal to mimic based upon the types of predators that are in the area. They have a great memory so they already have seen what is consuming what in their environment. By selecting an animal to mimic that predators around won’t bother the ensure their own survival.

They are one of the few species of Octopus that make tunnels and burrows under the sand at the bottom of the water. They are able to move along this way protected from various predators. At the same time, they are able to sneak up on their own prey and take them down without a battle.

Diet /Feeding

The location where these Octopus live are full of food sources for them to feed upon. That is why they commonly are seen around the bays of Malaysia. The main elements of their diet consist of worms, crabs, and small species of fish. They are also well known for taking part in cannibalism.

What is interesting about that though is that they will feed on each other when other food sources are around. Experts believe eat the cannibalistic acts have nothing to do with survival. Instead, they are about maintaining control over a given area of territory.

Their ability to mimic other animals also helps it to gain access to prey. For example, by imitating a crab in color and movement other crabs aren’t going to be afraid to be around it. Then when they get close they get consumed without having a clue what was taking place.

Scientists have recognized more than 300 Octopus species. They live in the oceans around the world. They are only found in salt water and they can live in regions that are either warm or cold. They range in size from extremely small to quite large. There is plenty of misunderstanding out there about these animals.

Reproduction

This Octopus has a reproduction process where the male places a sack of sperm inside of the mantle of the female. The male will die within a few months of this process taking place. The female will carry that sperm sac for several months until her eggs are ready to be laid.

As she lays strings of them she will use the sperm to fertilize them. She will keep the strings of eggs tucked protectively under one of her arms. Her suckers will prevent them from falling into the water as she moves around. As the eggs are ready to hatch she too will die. The young Mimic Octopus will have to fend for themselves from the instant they hatch. They will try to survive at the top of the water to find enough food.

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.

<strong>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.

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.
