I am taking the Marine Megafauna class at Duke University through Coursera. I just finished week 1 and took my quiz. I got 22/25. Here are some things I learned:
-The ocean is not uniform in salinity.
-One of the most important properties of seawater is its ability to dissolve salts, oxygen, and many other important elements and nutrients.
-Brackish water does not have the highest level of salinity that can still support life.
-Salinity and temperature determine the movement and ecological effect of a water mass.
-The benthos (or benthic zone) refers to the part of the ocean near the sea floor.
-Transitional forms of cetaceans had telescoping skulls.
