20 curiosities about octopuses based on scientific studies
Octopus is undoubtedly one of the most fascinating marine animals in existence. The complex physical characteristics, the great intelligence it possesses or its reproduction are some of the themes that have aroused interest in scientists all over the world, which led to the development of several studies.
CAT Spraying No More REVIEW
Cat Spraying No More is an excellent opportunity for the cat owners to learn about training the cat with a systematic approach. It helps in preventing the unwanted litter issues and other risks of bad feline behavior as well.
All these details served as inspiration for writing this article by YourCatCareguide, in which we compiled a total of 20 curiosities about powders based on scientific studies . Find out more about this wonderful animal.
The amazing intelligence of the octopuses
- The octopus, despite not being especially long-lived and expressing a solitary lifestyle, is able to learn and behave of its own kind by itself.
- They are very intelligent animals, able to solve complex problems, discriminate through classical conditioning and learn using observation.
- They are also able to learn through operant conditioning. It has been shown that one can work with them using positive rewards and negative consequences.
- Their cognitive ability has been demonstrated by conducting various behaviors depending on the stimulus present as a function of their survival.
- They are able to transport materials to make their own refuges, although they have difficulty in movement and may temporarily jeopardize their survival. In this way, they have the opportunity to subsist for longer.
- The powders apply a significantly different pressure when they are willing to manipulate different utensils, hold or, on the contrary, when they act defensive in front of predators. They have been shown to retain prey, as in the case of fish, much more intensely than the tools they can use for their protection.
- They recognize and differentiate their own amputated tentacles from other members of their species. According to one of the studies consulted, 94% of the octopuses did not eat their own tentacles, transporting them only to their refuge with their beaks.
- Octopus can mimic species of its environment that are poisonous as a form of survival. This is possible because of its long-term memory capacity, learning and defensive reflex memory, present in any animal.
- It has presynaptic facilitation of serotonin, a neurotransmitter substance that influences mood, emotions and depressive states in a wide range of animals. It is for this reason that “The Cambridge Declaration on Consciousness” includes the octopus as an animal that is self-conscious.
- The organization of the motor conduct of the octopus and the intelligent behavior that it possesses was fundamental for the construction of robots of great capacity, mainly due to its complex biological system.
Physical characteristics two powders
- Octopi can walk, swim and cling to any surface thanks to their strong and powerful suction cups. For this precision three hearts , one that works exclusively on your head and two that pump blood to the rest of the body.
- The octopus can not entangle itself because of a substance in its skin that prevents it.
- It can modify its physical appearance, as do the chameleons, as well as their texture, depending on the environment or predators present.
- It is capable of regenerating its tentacles if they are amputated.
- The octopus arms are extremely flexible and have a multitude of movements. To ensure its correct control, it moves through stereotyped patterns that reduce its freedom and allow greater mastery of the body.
- Their vision is color-blind, that is, they have difficulty discriminating red, green and sometimes blue shades.
- The octopuses have around 500,000,000 neurons , the same ones that owns a dog and six times more than a mouse.
- Each octopus tentacle has about 40 million chemical receptors , so each individual is considered to be a large sensory organ.
- As it is devoid of bones, the octopus uses the muscles as the main structure of the body, through their stiffness and contractions. It is a motor control strategy.
- There is a relationship between olfactory receptors in the octopus brain and its reproductive system. They are able to identify the chemical elements of other octopuses that float in the water, including through their suction cups.
