Octopus Species

Octopus Species Overview

Scientists have recognized more than 300 Octopus species. and there are hundreds more to be described and discovered. Scientists are still discovering new species. They live in the oceans around the world. They are only found in saltwater 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.

The structure of their bodies with very large heads and eight legs going in all directions can be unnerving to some. You have to agree that the design of their anatomy is unlike any other creature in the world. They are extremely flexible too which is really neat because they can make the shape of their body to fit anything, even inside of a bottle lying on the ocean floor.

In many cultures, they are deemed as evil creatures that lurk at the bottom of the water. They are said to be waiting for ships to destroy and men to drag under the water to kill. However, they are virtually harmless to humans and have no desire to be in confrontations. In fact, they prefer to run and to hide when they feel that they are in any type of danger.

All Octopus species consume crustaceans, mollusks, and fish. The majority of their food sources have shells on them. They will use their beaks to break the shells and consume the insides of them. When they can’t do that because of a very hard shell they will release a toxin from glands in their body. This toxin will dissolve the shell quickly and they can get to the source of the food.

All species of Octopus hunt at night and they have amazing vision. During the day they spend their time relaxing and hiding from predators. They have the ability to change their pigment so they can blend into surroundings. That’s right, they can hide in plain sight at times because they look just like what they are against.

It can be hard to study these animals in depth due to their location. They don’t do well in captivity though so that creates an additional burden. They are well known to be very intelligent animals though. They are also consumed by people all over the world as a great type of food. Sometimes they are the main course and other times they are a side dish such as Octopus rice.

All of the species of Octopus have a very short life span so they have to mature rapidly. Some have a cycle of life, reproduction, and death in less than a year. On average they won’t live for more than five years. Experts believe their bodies are pre dispositioned to shut down after they mate. That urge to mate is one that is instinct-driven and they can’t avoid.

The number of eggs that can be deposited can be up to 200,000. It really depends on the size of the Octopus and the species. The reason why they have so many eggs is that very few of them will be able to survive to maturity themselves. Octopus are very interesting animals and they give us plenty to think about.

There are quite a few differences among the species of Octopus out there. If there is a particular one you are interested in you can find photos of them and information about their lives. It can be fun as well as educational to explore many of the different species in great detail. You will find that information is lacking though for many of them. There simply isn’t enough research that has been done to give full details. Hopefully in time that will be information we have access to.

Seven-Arm Octopus

Seven-Arm Octopus – Haliphron Atlantic

Description

What makes the Seven-Arm Octopus stand out from the other 300 species is that it has one less arm than they all do. Well, that is how it appears anyway. They actually do have eight arms but one of them is extremely hard to notice. It is formed into a type of sac that is below the eyes. What is also known is that this look of seven arms is only for the males.

It is a very large species as well so it definitely gets quite a bit of recognition from both researchers and common people with an interest in these creatures. They can grow to a size of about 13 feet and weigh about 150 pounds. There is no size difference between males and females.

Distribution

This particular species of Octopus wasn’t identified until 2002. It was accidentally captured around the area of New Zealand. Researchers quickly took to the area to see what they could find out about them.

Behavior

This particular species of Octopus continues to follow suit with so many other species. It is highly intelligent with an ability to easily adapt to the environment. They are able to hide in cracks and crevices due to the flexibility of their bodies. They are also able to change colors to blend into their surroundings. They can do this by controlling their pigment.

Diet /Feeding

They consume a variety of different foods including fish, mollusks, and crustaceans. They tend to be opportunistic feeders instead of very picky as many other species of Octopus are. They have a very strong beak so they can almost always break through the shell of any food they capture.

When they aren’t able to they will drill holes in it and suck out the food source. As they attempt to capture their prey they can immediately immobilize them by biting them. This releases a very powerful venom into the body of their prey. These Octopuses do consume large amounts of food. They hunt at night and are able to sneak up on their prey due to blending in. They have remarkable eyesight so they have no trouble at all seeing in the waters.

<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.

Reproduction

When it is time for mating, the males will come into contact with females. It isn’t uncommon for the males to mate with several different females during a given season. The males will soon die after the mating season is over. This is due to a mechanism in their bodies that will shut it down after they are done creating sperm and depositing it into the body cavities of the females.

The females will carry the sperm with them for about four weeks before the eggs are ready to be fertilized by it. They can lay several thousand eggs at one time. They will find a place in the coral reef or in crevices to be able to deposit those eggs. The females stay very close to protect them from predators. They also keep them clean by blowing water on them and creating bubbles.

By the time that the eggs are ready to hatch the female is exhausted. She hasn’t eaten for a very long time and she is close to death. She won’t live long enough to see all of her eggs hatch. The young are able to swim and to find food on their own. They are vulnerable though and that is why the mortality rate is extremely high.

Human interaction

Sometimes this particular species of Octopus ends up tangled in the commercial fishing nets out there. It is believed they are following the sources of food in the water then this occurs. Many commercial fishermen are upset by the presence of this particular creature as it can result in lower yields of capture for them.

California Two-Spot Octopus

California Two-Spot Octopus – Octopus bimaculoides

Description

The California Two-Spot Octopus offers a very distinct appearance. It is also known by the name Bimac Octopus. They have blue spots around the eyes that can vary as far as the shade of it. The body spans about 7 inches in regards to the mantle. The arms though are considerably longer with a reach of about 25 inches.

The coloring for the overall body though can be very different, it all depends on where they happen to be in their environment. They are commonly a grayish coloring with yellow spots on them. They do have the ability to change colors though through the control of their pigments.

Distribution

With a name like this, there is no guess work involved with where they happen to be located. They do very well in the warm waters, from 65 to 72 degrees Fahrenheit. While that is where most of them live though there are some other locations they have for habitat as well. They include the waters of Mexico, Africa, and areas of Japan.

They tend to live about 65 feet below the surface of the water. Generally Octopus live much deeper so this gives people the opportunity to see them frequently compared to other species. Therefore they are in the shallow areas so they can reach the sandy bottoms of the water. They like to hide in rocks and crevices found there.

Behavior

When it comes to Octopus this is believed to be one of the friendliest species. They do spend most of their time isolated. However, if you are going to have a type of Octopus as a pet then this would be the one to have. They are very intelligent animals though so if you have one as a pet you need to be prepared. They are known to find ways to take the lids off of aquariums and escape.

They don’t seem to go into hiding as much as other species of Octopus in the wild. They seem to be more confident in their ability to blend in. They are tolerant of other types of Octopus around them too as long as they aren’t directly competing for food.

Diet /Feeding

The California Two- Spot Octopus has plenty of opportunity for feeding where they reside. A steady stream of mollusks and crustaceans are readily available. They are easily able to remove the shells from most of their prey. Those that they can’t are removed through the toxins in their saliva. These Octopus will also eat small fish when they have the opportunity.

Reproduction

Mating takes place at a young age for these Octopus as they have a life span of no more than two years. The males will avoid females until they are ready for mating, and then aggressively pursue them. It is common for them to mate with as many females as they can. After that period of time is over though the functions of the body simply start shutting down. The males won’t live more than a few weeks after mating.

The females have the same destiny, but first they have to fertilize their eggs with the sperm that the male has deposited into their body cavity. They will fertilize the thousands of eggs one by one. Then they tuck them under their arms in an effort to protect them until they are ready to hatch. Exhausted and without food for months the female will die as they start to hatch.

Human interaction

Many people have reported interacting with this particular species of Octopus due to the shallow waters where they live. Generally the Octopus will swim away in a hurry. Sometimes it will release ink too in order to help them get away without being followed. They aren’t dangerous to humans so there is nothing to worry about if you are in the water with them.
