They are some of the most mystifying creatures that people have been thinking about and winding up fascinated by throughout the ages. Their characteristics, advanced problem solving, and survival skills employed them to be among the ocean's most interesting residents. Here we attempt to unearth 12 interesting lesser-known facts about the octopuses and dig a little deeper into some of their excellent abilities. We'd be able to answer all the key questions on what makes them so special: Are they fish? And many more.
1. Octopuses Have Three Hearts and Blue Blood
There are many fantastic facts about an octopus, but one thing that stands out is that they possess three hearts. There are two for circulating blood to the gills and one for the rest of the body. The blood is also blue; this is because it is chock-full of copper, containing a protein called hemocyanin, which aids in transporting oxygen much more effectively in cold, low-oxygen environments - in this case, deep ocean waters.
2. They change colors in the blink of the eye
These chromatophores beneath an octopus's skin are saviors that make them really masters of camouflage. These cells can actually change the color and even texture of their bodies within the wink of an eye so that they can really blend with everything that is going on around them. The camouflage isn't merely to hide but also for communication and some other mating rituals.
3. Octopuses are Extremely Intelligent
Arguably the smartest of invertebrates are the octopuses. There have been known uses of tools, solving puzzles, and even successful escapes from tanks. One of the most world-famous examples was that of an octopus named Inky, which managed to escape from a New Zealand aquarium, and showcased great problem-solving skills.
4. Amazing Regeneration Ability
An octopus can develop a whole lost arm to replace it with an arm full of all its original functionality, tasting and holding objects with its suckers after some time. It is the most vital survival tactic. Losing an arm for them lets them avoid predators but then regrow it.
5. Octopuses Have Suction Cups That Can Taste
All the arms of an octopus possess millions of strong suckers. Maybe, you do not know that the suckers can taste whatever food they encounter. Each cup possesses a chemoreceptor which, therefore allows the octopus to sample its environment for something edible or not.
6. They are solitary but not antisocial
Although octopuses are mainly solitary in their nature, they are sometimes known to show sociality, particularly while mating. There are some reports indicating that these marine animals do communicate with other animals and they become allies for instance, as a means of self-defense or if there is the need to share food.
7. Octopuses Can Crawl Through the Narrowest Holes
The octopus doesn't have a skeleton; the body is almost entirely soft and flexible except for the beak, which is chitinous, like a bird. This allows them to squeeze through the narrowest holes, sometimes no wider than their own beak. It is the flexibility for escaping from predators or hiding in narrow crevices.
8. They Have an Extremely Short Life Expectancy
Octopuses are intelligent and relatively malleable creatures, although they have not very long life cycles. The giant Pacific octopus lives up to 5 years, while most of the species in the species die shortly after breeding. Females normally die after completing raising their eggs, in certain occasions starving for months in the process.
9. Octopuses Use Jet Propulsion to Move
When an octopus wants to make a quick getaway, it does so by jet propulsion. The water from its mantle cavity is forcibly expelled out of a siphon as it takes advantage of the thrust of the expelled water to keep moving forward at a high speed. Coupled with their capability to change color, puts them in first class in the area of predator evasion.
10. They Can Mimic Other Animals
Some species of octopuses even employ other forms of sea creature imitation as their defense mechanism. A very popular mimic is, in particular, the mimic octopus, which can impersonate much stronger animals such as lionfish, sea snakes, and flatfish. All these may help it avoid becoming a prey.
11. Their Ink Is a Powerful Defense Mechanism
A threatened octopus may release a dark cloud of ink that both clouds its escape route and holds a chemical which numbs the scent perception of a predator. This gives the octopus only enough time to get away to safety. Ink is a matter which is derived from melanin, the same coloring agent responsible for human skin and hair pigmentation.
12. Octopuses Have Been Around Since Sailing Ships
They are some of the most ancient ones that exist, existing over 300 million years ago, older than dinosaurs; in their life span, they can only live for very short periods but have the capacity to adapt and thrive for long.
What is the Short Note on an Octopus?
An octopus is a soft-bodied sea creature with eight arms that can change color, regrow limbs, and escape from narrow confinements. It has three hearts and blue blood and uses tools; therefore, it is the most intelligent invertebrate alive on this planet. Intelligently, though, octopuses only live for a few years, and most species do not reach five years of age. The solitary lifestyle of the octopuses is complemented by complex behavior during mating.
Is an Octopus a Fish?
No it is not a fish. An octopus is of the class cephalopods as a mollusk. Comparatively, there are no bones in the bodies of the octopus and they have eight arms with suction cups. On the other hand, fish have backbones, scales, and fins. The way it swims through jets, and changing color ability is pretty special among the marine animals. So, in summary, even though they share the ocean with fish, the octopus is a completely different type of sea creature.
