The movie My Octopus Instructor (2020) paved the best way for finding out the intelligence of the exceptional eight-armed creature. One final result has been extra consideration paid to different exceptional tales of human–octopus friendships.

At Hakai Journal, we find out about a part-time science trainer who befriended an octopus and discovered a tragic fact about her eight-armed companion:

One of many first octopuses Nitz raised was an algae octopus (Abdopus aculeatus) she named the As soon as-ler after the narrator of The Lorax by Dr. Seuss. She and her daughters would stand in entrance of the As soon as-ler’s tank and wave their entire arms as if they had been undulating blades of kelp. Ultimately, the As soon as-ler began waving again, imitating their actions with a single arm whereas retaining all of the others tucked neatly beneath her or caught to the glass. It grew to become a frequent ritual.

When the As soon as-ler began laying eggs, Nitz steeled herself for what would occur subsequent. As feminine octopuses brood, they change into sluggish and begin to deteriorate, dropping pigmentation and muscle tone and forming lesions that by no means heal. The As soon as-ler spent most of her time with half her physique inside her den, guarding her eggs, sometimes extending an arm to probe a chunk of meals, although she finally stopped consuming altogether. One morning, Nitz awakened and located 1000’s of child octopuses, every smaller than a grain of rice, bobbing and spinning by way of the tank. The As soon as-ler had torn aside her den to assist her kids swim free. Now, she was sprawled on the underside of the tank, sickly pale, her mantle heaving with each labored breath. Nitz sat in entrance of the tank along with her daughters, her hand on the glass, crying softly as their beloved octopus’s respiratory grew to become slower and heavier. Out of the blue the As soon as-ler did one thing none of them anticipated in these final moments: she inhaled deeply, raised her arm, and waved. “I waited for extra breaths, however there weren’t any,” Nitz remembers. Possibly that remaining gesture was merely a muscle spasm brought on by short-circuiting neurons. Maybe, of their grief, Nitz and her household had been seeing what they wished to see. Nonetheless, Nitz says, “it felt for all of the world like she was waving goodbye.” 


It’s unimaginable to know if the octopus was waving goodbye. A cat who’s about to be put to sleep by the vet (as a consequence of, say, no-longer-treatable kidney failure) can simply be interpreted as appearing like he is aware of he’s about to die. However we people are most likely over-interpreting his habits.
