Facts About the Octopus
- Not all eight appendices to the octopus are arms. Scientists believe that two of them act as legs to push along the seabed.
- If an octopus loses an arm (or leg), one can be regenerated to take his place.
- There are three hearts to the pulp and dark blood.
- The octopus has a sharp beak called a radula, and a toothed tongue.
- The radula is used for drilling into prey shells.
- When within the shell a poisonous paralytic can be released by an octopus.
- We have no external structure but the brain is covered by a skull.
- An octopus has many defensive strategies, including the camouflage of their skin by colour, shape and the adaptation of body posture to blend with their environment.
- Octopi, for fear, can change color to reflect their mood white, and red for rage.
- Octopus will release a violet ink and drive away from a threat.
- They can attain speeds of up to 40 kilometers (or 25 miles) per hour.
- After mating, female octopus release more than 100,000 eggs but only a few of them reach adulthood.
Some More Amazing Facts About the Octopus
- Cephalopods climate and lifestyle means they need to be able to perform complex and adaptive behaviours.
- We need to learn, understand and recall their surroundings and other animal behaviour, as active predators.
- They are the first invertebrates that can be seen using tools, such as using coconut shells to hide from possible predators and using water rocks and jets in a manner that could be defined as tool use.
- Local octopuses may collect shells of crustaceans and other items around their lairs to construct fortresses or gardens. Some bits of pulp bear protective shells.
- The common octopus has a wide range of techniques it uses to avoid attackers or to thwart them. Their first and most impressive line of defence is their ability to hide in the open. The popular octopus can almost immediately match the colours, patterns, and even textures of its environment using a network of pigment cells and specialized muscles within its skin. Predators like sharks, eels and dolphins pass by without even noticing.
- They were found to be playing with a ‘toy’ and have individual reactions and individual temperaments, with some scientists suggesting they have different personalities.
- All pulp are poisonous but only the small blue-ringed pulp is considered to be deadly to humans.
- There are about 300 recognized species of octopus, which is more than one-third of the total number of known species of cephalopod.
- Octopuses have 4 pairs of arms.
- There are three hearts to the pulp. Two blood pumps through each of the two gills, while the third flow through the abdomen.
- On detection, an octopus releases a cloud of black ink to hide the vision of its attacker, allowing it time to swim away. The ink also contains a substance which dulls the smell of a predator, making it harder to track the fleeing octopus.
- Fast swimmers, expelling water through their mantles, they can jet forward. And their fragile bodies, without any internal or external skeleton, can squeeze into unmistakably tiny cracks and crevices where predators can not follow.
- The spectacular mimic octopuses will adjust their body shape to imitate other species.
- They do have beak-like teeth, which can deliver a harsh bite, and venomous saliva, which is primarily used to subdue prey.
- If all else fails, an octopus can lose an arm to escape the grip of a predator and then re-grow it without permanent damage.
- These are some stunning facts about poultry.
COOL FACTS ABOUT THE OCTOPUS
OCTOPUSES CAN CHANGE COLOR
Their cells contain something called chromatophores, which are essentially tiny balloons which they can contract to create different colour shades. At the same time, they can also generate several colours. We usually use this to hide from predators or to interact with one another.
OCTOPUSES ARE HOMEBODIES
Don’t confuse them for the sake of shyness, but don’t expect them to be party life either. Octopuses are solitary animals who don’t go to schools or interact outside of mating with others. They normally hide in caves, unless they search for food or something along those lines.
OCTOPUSES ARE DEDICATED AND DEADLY LOVERS
Octopuses mate only once in their lifetime and the females eat the males afterwards. They do this because they stay with their eggs until starvation for as long as they can. Typically the males can be distinguished by their hectocotylus, which lies at the end of their arms which is how they can mate.
OCTOPUSES ARE ESCAPE ARTISTS
The octopuses are incredibly agile to fit into virtually any crevice or space. The only part of a strong body is its beak. Even with that, they can squeeze into the tiniest spaces without injury or problem. They can also get themselves out of small jars and aquariums. In order to keep them enclosed, aquariums often have to build special enclosures with astroturf (octopuses dislike the texture).
OCTOPUSES MAY LAY UP TO 100,000 EGGS
Up to 100,000 eggs can lay when mating. Baby octopuses are just the size of a grain of rice when hatching and only the size of a quarter after one year. The shear number of baby octopuses counteract the other dangers that they face after hatching.
OCTOPUSES HAVE HUGE BRAINS
By imitating one another, they can retain short-term knowledge, escape from enclosures and learn. Octopuses are definitely one of the most intelligent marine creatures out there. Octopuses and their relatives (cuttlefish and squid) represent an island of invertebrate animals in the sea of mental complexity. One generalization is that they have nine brains, with one unified brain in fact they have nodes all over their bodies.
GIANT OCTOPUSES REALLY DO EXIST
The potatoes can grow up to 30 feet and weigh 600 pounds under the right conditions. The Giant Pacific Octopus, usually found on North America’s northwest coast, will hit those heights if there’s plenty of food and health. The Giant Pacific Octopus will only live for up to five years, and up to two years for most others. This is an amazing Facts About the Octopus
OCTOPUS SPECIES ARE STILL BEING Found
Identification of all octopus species in the world will be unlikely. We have been able to categorize 300 different species so far, and have barely made a dent. The majority of its species and habits can not be accurately classified.
OCTOPUSES ARE THE HEARTS KINGS / QUEENS
Octopuses usually have three heart. They are Cephalopods, which means they have more than one heart that allows their whole body to pump blood. When they swim one of the hearts stops beating.
THE TINIEST OCTOPUS
Octopus Wolfi is the smallest known to date. They measure less than 1 inch and weigh less than 1 gram. It was discovered in 1913 and from that tiny creature we still have a lot to know.
OCTOPUSES ARE BOTH WARM AND COLD Species
The octopus can live in both warm and cold water while it is only present in salt water. The species that live in colder water appear to be smaller with the larger cold water species also affecting their reproductive capabilities.
