- Sometimes, the octopuses also undergo autotomy of limbs to save their life from the danger. Isn’t it one of the amazing octopus facts?
- There are specialized skin cells in octopus that are capable of changing the apparent color, opacity and the reflectivity of the body’s external layer (epidermis).
- Though majority of the octopus species use three different colors for camouflaging, there are some that can switch to any of the five colors, viz. black, brown, red, orange and yellow.
- Besides being used as a defense measure, the color changing ability is also utilized for warning or communicating with other octopuses.
- Chromatophores, iridophores and leucophores are the three types of cells that are responsible for color changing in octopuses.
- When disturbed, the highly venomous blue-ringed octopuses change their appearance to bright red.
- For achieving greater camouflage, these mollusks can change the texture of their body by the use of muscles in their skin.

- A limb severed from the body of an octopus remains sensitive to stimuli. So unpleasant sensations cause distraction for it.
- Do you know the most intelligent of all invertebrate animals is none other than octopus?
- These animals show high degree of sensitivity to the environmental stimuli as it has been confirmed through scientific research.
- They not only understand the behavior of their prey but also remember its habitat that is an essential trait of a predator.
- The research works investigating the learning behavior of octopus indicate that it can learn through observation.
- These cephalopod mollusks also have the ability to solve problems. For example, these have been seen as unscrewing a lid to get prey or food from the container.
- Have you heard of Paul the Octopus, an octopus that lived from 2008 to 2010? He made several predictions about the finals of football association’s matches which often came true!
- Octopuses are known for constructing gardens and fortresses around their lairs for which they use crustacean shell and other similar objects.
- After having noticed their individualized responses and temperaments, the scientists have developed a view that each individual member of the family has its own personality.
- The venomous saliva, ejected from their mouth, helps in subduing and killing the prey. There are also beaklike jaws that can deliver a nasty bite to the victim.

They can not only switch their appearance into five different colors but also mimic the body shape of other animals. These are the tactics for defense against any possible danger to their life. Other safety measures include autotomy of limbs, ejection of venomous saliva, construction of gardens and fortresses and the use of ink sacs. So surprisingly, octopuses are the most intelligent of all invertebrate animals on earth. As an essential trait of a predator, these creatures have ability to remember the habitat of their prey as well as comprehend their behavior. At the same time, their capacity to learn through observation is also something worth noticing.
