A new study examines the seemingly crucial role of a protein acetylcholinesterase (or AChE).

The females don’t eat during the last month before they lay their eggs. Only the biochemistry in their bodies had already started changing. And now we are finally just getting a look at the mechanisms behind this impressive process. These findings don’t solve the mystery of such detailed tissue regeneration.

The film closes on a more uplifting note, ending with a scene showing Foster and his son discovering a small, delicate octopus while diving together, who they imagine is the offspring of his old friend. Once the eggs form they will stay within her body for a period of several months.

But the biological secrets inside their arm regeneration feat do hold the promise of learning more about how we might better regenerate our own diseased or lost tissue. They also point to more molecular medical work.

Researchers studied six healthy (eight-armed) female common octopuses (Octopus vulgaris), captured off of the Italian coast. As with most creatures, the octopus's main purpose in life is to reproduce. They do develop an instinctive urge to mate as the age of maturity arrives. And for the next hundred days or so, the arm tip grew back in to resemble the original one. And that's all cephalopods can do, too. What could be orchestrating all of these specific steps? It takes months before they are able to move to the bottom layers of the ocean floor. Anyone need a new arm? Such a toehold could help us make new leaps into regenerative medicine.

I just finished watching ‘my octopus teacher’ on Netflix which was really pretty, although it sort of got me a bit angry again at level of compassion from documentary makers trying not to get involved or meddle in nature’s affairs, while a creature is clearly in need of their help. 463, This story has been shared 460 times. "By targeting the AChE activity at single specific regeneration states, it will be possible to study the regenerative process in its proceeding and regulate phases of the reparative pathway," they noted. Depending on the species, he will either approach a receptive female and insert the arm into her oviduct or take off the arm and give it to her to store in her mantle for later.

Keeping these eggs save can be a very difficult job for a female Octopus. The octos were put under anesthesia and a small tip (just one to two centimeters) from each arm was removed. The process of mating is very unusual as the males use one of their arms to place a sack of sperm into the body cavity of the female. She will be close to death by the time the young arrive.

Adults usually weigh around 15 kg (33 lb), with an arm span of up to 4.3 m (14 ft). And further molecular signals were responsible for the “hook-like structure” that was visible at the end of the arm in the second week.
