Ocean acidification may be shrinking the brains of the world's most intelligent invertebrates
Researchers found high-CO2 seawater cut squid brain volume by 49% and reduced hunting by up to 65%, raising survival concerns.

Madrid. An ongoing research project at the University of Acadia in Canada explores the effects of rising levels of ocean carbon dioxide on squid neurology. Its results, presented at the conference of the Society of Experimental Biology in Florence, Italy, reveal that exposure to future levels of ocean acidification could reduce its brain volume by approximately 50 percent.
Climate Change Could Shrink the Brain of One of the Ocean's Most Intelligent Creatures
A bigfin reef squid. —Reinhard Dirscherl/ullstein bild—Getty ImagesSquid are among the scholars of the deep. Distributed across all of the world’s oceans, the 375 squid species can navigate mazes, cooperatively hunt, communicate via color change, recognize individual humans, and learn from past experiences—such as remembering how to escape from an enclosure. Neuron by neuron, squid have brains about as complex as that of dogs, and along with oct…
Ocean acidification may be shrinking the brains of the world's most intelligent invertebrates
An ongoing research project exploring the effects of rising levels of oceanic CO2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe brain shrinkage appears to be most pronounced in the areas that interpret visual information, correlating with significant reductions in normal feeding behaviors and suggesting serious consequences for the future of squid and other cephalopods.
The pH value of the oceans decreases continuously due to human CO2 emissions. Now it has been discovered that squids form significantly smaller brains in acidic water and develop a restricted hunting and eating behaviour. Taipei (Taiwan). The seas have absorbed about 25 to 30 percent of the CO2 emissions that have been emitted since the beginning of industrialization. The average pH value at the sea surface has thus decreased from about 8.2 to a…
