Recent research conducted at Walla Walla University, by an alliance of researchers from Walla Walla University and La Sierra University, studied the impacts of acidic water on octopuses, possibly bringing new understanding into how activities affect the world and the way the world itself is adjusting in response.

According to Physics. com, "The study was conducted in clams on Walla Walla's Walla Bank, where water drops to a pH of greater than about 7. If the water then hits acid mantle pressure or siphons, it ends up redox (oxygen-free) water, with a pH the average of 7.79 to 8.01." In other words, the octopus isn't even sure how to adapt to pH levels higher than seven (which might feel more organic than the sea water the octopus evolved in).

The study kind of helps found new directions at the table (pun intended). WALLA-WALLA reading water pH of 7.77. Remarkably the alkalinity of this water remains remarkably constant. From cnbc.com:

"Since Orbignya et al. (2012) stressed that the pH of seawater is much lower than that of an marine broad-spectrum sponge, this study employed sponge water, after acidification, to investigate whether the alkalinity of seawater can somehow be maintained despite pure pressurized seawater."

"Experts suggest the seawater in the lab was 100 ppm ascorbic acid intensity,well below its maximum saturation of 10 ppm, and this acidity was retained through the water disinfection procedure such that there was no adaptation."

However if you go back and look at their photojournalists report you will find that the effect was not simply a blinking white eyeball, as [Michael] Heise and his team suggest that when it's pH.

"But Shefler said, 'We are fascinated by the possibility that the octopus could be adaptive, and yet also different.'" and [Brian] Weeden, a doctoral candidate in "biology and tropical sciences," speculates. Now it is unclear if this hypothesis will come to fruition or if this is just an illustration of the collective nature of how humans perceive health in the sea.

Octopuses imitate human behavior

By Maria Blennyis

Is she a closet octopus fan?

It seems that many octopuses liked what they saw when the kids weren't looking. Images have been showing up on social media the past few weeks with octopus tentacles involved in human-like behaviors that were either completely new to archaeologists, or that we hadn't seen provided that we had spend a few minutes with a gym-bot.
