According to Dr. Alex Schnell, working with octopuses is difficult because of their emotional swings. They might be outgoing and social one day and then refuse to leave their den the next, according to a cephalopod behavioral ecologist.
Aggressive Cephalopods
(Photo : Pia) My initial reaction to the experience, which I was able to capture on video, was horror, accompanied by curiosity. I had never seen an octopus up close before, but I was more fascinated at the moment. Remember, I was with my daughter, and I m sure every father can relate to being more defensive of her than afraid of the danger, Karlson said.
The former lifeguard left the octopus behind and went to put up a shelter for his wife and daughter farther down the beach.
Karlson was floating in the sea on his own about 20 minutes later (having swum there many years before) when the octopus reappeared - he was whipped around his left arm when gazing at crab shells in water about 1.5 meters deep.

Humans have the ability to experience a wide range of pains, from mourning to famine, and worst of all is - hitting your toe in the morning of a cold winter.
Pain was seen to be a far easy concept for invertebrates as a way of trying to ammend something that is affecting the body via reflex. However, new research depicts a different image for the perception of pain among one of the most alluring and clever invertebrates on earth which is the fish-punching octopus.

The Three Parts Of Octopuses Pain
A Journal that has undergone enhancement but yet to be a definitive version of record that is to appear in the journal iScience talks about the pain of octopuses in three major parts.

Scientists in Israel, in a serendipitous discovery while studying the causes of skin colour changes in the cephalopod due to light, have made a shocking discovery. They found that octopus arms can sense a beam of light and evade it even when its eyes cannot see the light.
In a series of tests and investigation, the scientists discovered that shining a light on an octopus s arm caused the animal to repudiate it, even when it was slumbering, and while the source of the light was present on the other side of a small opening into which its arms could fit but the light was unseen to its eyes.
