Fact Friday
The ocean absorbs much of the excess carbon dioxide produced from the burning of fossil fuels. As the ocean absorbs this rampant increase in CO2, it reacts with sea water, changing the ocean’s chemistry. This process is called ocean acidification, and we are already seeing the negative impacts in our oceans. Here you can see the shell of the pteropod exposed to ocean acidification on the right is weaker and has visible damage, making it harder for the animal to survive.

French Angelfish
“Til death do us part.” It’s common to find fish that mate for life in a coral reef ecosystem. French angelfish exhibit permanent, monogamous breeding pairs. Mating for life comes with benefits. These fish cooperatively feed and defend their territory from other fish. This is much easier to do with two fish, rather than one.
