According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
I think it's super fascinating that cleaner wrasse fish could possible self-aware. People typically think of fish as unintelligent creatures, but that's clearly not true for this fish. The part where the scientist injected the cleaner wrasse fish with harmless brown gel and then saw the fish attempting to scrape off the gel as if it were a parasite, once they saw themselves in the mirror, was super interesting. Humans do a similar action to this such as popping pimples, once they are aware they have one after looking in the mirror.
