Octopuses do have a high IQ as octopuses are incredibly and highly intelligent creatures.
Octopuses are considered to be the most smart of all invertebrates and display amazing cognitive abilities, which also rival many mammals and birds.
Research has also found that octopuses have a high volume of jumping genes or transposons, which are sequences of DNA that jump around the genome, which are also linked to advanced learning and memory in human brains.
Octopuses are masters of disguise and change their skin color, texture and shape not to just hide, but to also actively trick their prey or deter predators.
And octopuses also have both long term memory and short term memory and have even demonstrated an incredible ability to recognize individual people.
An octopus also has a decentralized nervous system and while octopuses do have a central brain, around two-thirds of the octopuses neurons are actually instead located in the octopuses arms.
Because two-thirds of the octopuses neurons are located in their arms, it means that each arm of the octopus can also taste, touch and operate somewhat independently.
Octopuses can also solve complex mazes as well as navigate sequential puzzle boxes, open jars that are child proof and even use coconut shells that are discarded as portable armor.
Octopuses do have two genders as there are distinct male octopuses and female octopuses.
In most species of octopuses, the female octopus is often larger than the male octopus and they can also be identified by looking at the tips of the octopuses arms.
Male octopuses have 1 specialized arm that is called a hectocotylus, which lacks suckers at the tip and has a modified scoop or groove that is used to transfer the sperm to the female octopus.
And female octopuses have suckers that extend to the very end of all 8 of their arms.
Octopuses do have the ability to hear you, although octopuses don't have any ears.
While octopuses don't have ears, octopuses can still hear, which they are able to do by detecting sound vibrations using special organs that are located behind the octopuses eyes.
The special organs that octopuses have behind their eyes that allows them to detect sound vibrations are called statocysts.
The statocysts that octopuses have that allow them to detect sound vibrations are fluid filled sacs that are lined with sensory hairs that sense the movement of water particles.
Because octopuses lack traditional ears like humans and other animals, an octopuses auditory experience is different from our hearing.
An octopuses hearing is limited to lower frequencies, which often range from between 400 Hz and 1000 Hz, with the best sensitivity occurring around 600 Hz.
And instead of processing acoustic pressure waves, like humans do, octopuses instead essentially feel the acoustic particle motion and vibrations through their statocysts and bodies.
An octopuses hearing is also considered one of the octopuses weaker senses.
Although it's also believed to be vital for the octopus to detect low frequency rumbles of any approaching predators like eels, sharks and marine mammals or even for eavesdropping on nearby prey.
Octopuses can also recognize humans and individual humans.
Research also demonstrates that octopuses, which are very highly intelligent invertebrates can also tell people apart, even when the people are wearing identical clothing or uniforms.
Octopuses can also remember past interactions and sometimes even develop distinct favorites and nemeses.
Octopuses also have 2 biological sexes, which are male and female as they do reproduce sexually and distinguishing between the sexes of the octopuses comes down to looking for a single and unique reproductive organ.
Male octopuses don't have a penis, but instead male octopuses have a specialized mating arm that is called a hectocotylus, which is often located on the third right arm.
The arm lacks suction cups at the tip and is used to deliver sperm packets also known as spermatophores directly into the female octopuses mantle cavity.
Female octopuses don't have the specialized arm and all of the 8 arms of the octopus are identical.
Female octopuses also have a mantle cavity that is used for receiving the male octopuses sperm packets, which they often also store to fertilize their eggs at a later time.
In some species of octopuses, like the blanket octopus, male and female octopuses are so drastically different that they also exhibit some of the most extreme sexual dimorphism in the animal kingdom.
Female blanket octopuses can also grow up to 6 feet long and male blanket octopuses average just 1 inch long.
