Octopuses have 8 arms with suckers in the form of concave spheres on the arms that are used to move on the seabed and catch prey. The highly flexible body allows the octopus to slip into very narrow rock crevices in the seabed, especially when escaping from predatory fish such as the Moray eel. Lesser-known octopuses from the suborder Cirrata have two fins and an inner shell so their ability to slip into tight spaces is reduced.
Octopuses have a relatively short life span and some species only live as long as 6 months. Larger species such as the giant North Pacific Octopus which can weigh up to 40 kilograms can live up to 5 years under suitable environmental conditions. Reproduction is one of the causes of death, male octopuses can only live a few months after mating and female octopuses die shortly after laying eggs. Death is due to the octopus’ neglect to eat for about a month while guarding the unhatched eggs.

Sense in Octopus
Octopuses have an incredibly sharp sense of taste. The suction device on the octopus’ arm is equipped with chemoreceptors so that the octopus can feel the object it touches. The octopus moves by crawling or swimming. Octopuses just crawl plus a little swim if they want to move slowly and only swim if they want to move quickly. It can move very quickly when they are hungry or when they are in danger. Octopuses can sense texture variations in objects they touch but cannot combine information to guess the shape of the object being touched.
The octopus is crawling The autonomic nervous system in each arm makes it difficult for the octopus to know the consequences of the movements made. The octopus brain issues higher-order commands to move the arm, but the more detailed instructions for moving the arm are provided by nerve cords. Octopuses don’t have a nervous system that gives feedback to the brain about the success of the brain’s command to move the arm, so visually observing arm movement is the only way for the octopus to know if the desired arm has moved or not.

The Intellegency of Octopus
Octopuses have a very complex nervous system with only a few localized in the brain. Two-thirds of the nerve cells are found in the nerve cords in the eight arms of the octopus. Octopus arms can perform a wide variety of complex reflex movements, triggered by 3 different stages of the nervous system. Some types of octopus such as the octopus octopus can move their arms to imitate the movements of other marine animals.
In laboratory experiments, octopuses can easily differentciate to distinguish various shapes and patterns. Octopuses can also open the lid of a jar by learning from sight alone, although this discovery is often contested for various reasons.
Octopuses find making movements that some people think are like playing games. Over and over again, the octopus releases bottles and toys in the middle of a circular current of water in the aquarium and then tries to catch them. Octopuses often break the aquarium they live in and sometimes come to other aquariums to look for food. Octopuses are also known to often climb fishing boats and open fish storage rooms to eat crabs.
