What makes the octopus unique?

This blog is almost, but not entirely, about Rh negative blood and issues. It is also about things I have learned many Rh negatives to be interested in. Which includes me. When I find something of interest to me, I will share it.

This one is about octopi. The first one is new to me, the other two I know. Nevertheless, here is the list of three:

1)

They feel pain.

Eating them alive is not cool. Here is what I’ve found so far:

A science-based report from the University of British Columbia to the Canadian Federal Government has been quoted as stating “The cephalopods, including octopus and squid, have a remarkably well developed nervous system and may well be capable of experiencing pain and suffering.”

Pain in cephalopods is a contentious issue. Pain is a complex mental state, with a distinct perceptual quality but also associated with suffering, which is an emotional state. Because of this complexity, the presence of pain in non-human animals, or another human for that matter, cannot be determined unambiguously using observational methods, but the conclusion that animals experience pain is often inferred on the basis of likely presence of phenomenal consciousness which is deduced from comparative brain physiology as well as physical and behavioural reactions.

Most animal welfare legislation protects only vertebrates. However, cephalopods have a special position among invertebrates in terms of their perceived ability to experience pain, which is reflected by some national and international legislation protecting them during research.

2)

They can change colors while sleeping/dreaming.

In case you’re wondering, this picture is real from an octopus in a fish tank in the middle of a living room.

3)

Their blood is copper-based and therefore blue.

To survive in the deep ocean, octopuses evolved a copper rather than iron-based blood called hemocyanin, which turns its blood blue. This copper base is more efficient at transporting oxygen than hemoglobin when water temperature is very low and not much oxygen is around.

    I have watched a few documentaries on the octopus. I find them to be so interesting. On Netflix just watched a documentary called my octopus teacher. It was really awesome. So smart. On you tube they had videos testing there intelligence. As humans the arrogance to believe we are smarter than animals is irresponsible to some extent. Dolphins have more grey matter than humans placing there intellect above ours. Like ken mentioned the African grey parrot very intelligent…But the octopus is mysterious. There was an article of a Russian Science Team that drilled deep into a lake in Antarctica. The claims said that the octopus could shape shift into what looked like a human…apparently that mission did not turn out well. The divers died from this octopus…so much to learn…incredible.

      That was awesome!!!!!Laughed so hard! My daughter and I always believed that our animals understood us. Finally science has backed up our belief that animals are very intelligent. When you respect all forms of life, then you are interested in listening and learning. If a water molecule can freeze into a beautiful shape from positive or negative shape from the simple projection of positive and negative words spoken during formation.( I think mike posted video on this ) how can we not believe in the incredible intelligence of all creatures. I’m not a person who laughs alot, but my daughter can always find and awesome video on you tube like this that makes me laugh. So many stories…one I recall a swimmer was protected from sharks and guided to safety by a group of dolphins…I watched a scientist who studied the frequencies of dolphins and concluded they were having conversations…Its awesome!!Thanks Ken!!!

    fwiw: “” Indian Ringneck Parakeets Are Excellent Talkers
    While it’s never a sure thing that your bird will be able to learn to talk, opting to adopt an Indian ringneck parakeet will certainly up your chances. These birds are notorious talkers. In fact, they were once considered sacred in their native environment based on their remarkable ability to mimic human speech. Long ago, religious leaders in India observed the birds repeating prayers that were recited daily in the gardens surrounding their places of worship.

    The clarity of their speech, along with their ability to learn dozens (if not hundreds) of words, still continues to surprise people. Ringneck voices are one of the most charming among companion birds, as they tend to be comically high-pitched. They typically start talking between 8 months and 1 year old and are quick learners, especially if their humans spend quality time talking to them every day. “” https://www.thesprucepets.com/facts-about-indian-ringneck-parakeets-390271
