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.
Ocean acidification, caused by increased human carbon dioxide emissions into the atmosphere, could shrink the brains of squid, according to preliminary results from an ongoing research project presented at the annual conference of the Society for Experimental Biology in Florence, Italy, on July 8. The two researchers behind this research project raised squid in two parallel tanks: one replicating the (...) Read more In brief / Animals , Oceans
