Octopus Opens Jar from Inside of It
If you put an octopus in a jar, it will be able to set itself free.
People may be the most intelligent creatures on Earth, but there are plenty of smart animals living beside us.
We know that, we have dogs.

Hardly anyone expects any smart conduct, logical actions or signs of attentiveness from mollusks, though.
This octopus surprised everyone!
According to Live Science, octopuses are ocean creatures that are most famous for having eight arms and bulbous heads. Some other fun facts: They have three hearts and blue blood; they squirt ink to deter predators; and being boneless, they can squeeze into (or out of) tight spaces. They are quite intelligent and have been observed using tools.
Some people call their appendages tentacles, but that is incorrect; they are arms. Most octopus species have suction cups on the bottom of each arm. The arms seem to have a mind of their own.
In fact, two-thirds of an octopus’ neurons are in its arms rather than its head. That means that an octopus can focus on exploring a cave for food with one arm while another arm tries to crack open a shellfish.

Some octopuses even have warts. Two deep-sea octopuses in the Graneledone genus — G. pacifica and G. verrucosa — have skin bumps dotting their pink-hued mantles. These warty protrusions, it turns out, can be used to distinguish the two species, which have been incredibly difficult to tell apart.
Scientists reporting June 7, 2017 in the journal Marine Biology Research catalogued the distribution of warts on both species, pinpointing two variables that were consistent across the individuals within a given species: distance between the warts and the tip of the mantle and the extent to which the skin bumps spread down the creature’s arms.
Octopuses have an excellent sense of touch. Their suckers have receptors that enable an octopus to taste what it is touching.
