Also, here is a map to reference each body of water listed above.
In late 2008, I wrote a very simple post explaining ‘salinity’ and the overall general amount of salt in the ocean. Now, with new data being collected by NASA (in a joint mission with Argentina) using the Aquarius instrument aboard a satellite, Satélite de Aplicaciones Científicas, we are able to more completely understand “How salty is the sea?” The satellite measures the “brightness temperature” of the top centimeter layer of ocean waters.
June 10, 2012 marked was the one year anniversary this satellite has been in orbit. In the past year many finding have been confirmed using three sensors to collect approximately 3.6 million measurements (300,000 measurements per month)! For instance, 1) the Atlantic ocean is saltier than the Pacific ocean, 2) long rivers are responsible for massive plumes of freshwater that extend far into the sea (e.g., Mississippi River carry lots of freshwater into the Gulf of Mexico, the Kissimmee River, Lake Okeechobee, and the Everglades flowing into the Florida Keys region), and 3) rainfall along the equator’s rainforest create a significantly more diluted ocean than we once previously had envisioned.
Trivia question: Can anyone tell me the what you call the body of water where freshwater from rivers mix with the salty ocean water?

Yes, that is correct – April is National Frog Month. However, this is not a post about the amphibian, but is all about the frogfish! Contrary to popular belief, it’s easy being green if you’re a frogfish. First of all, you can change colors from green to black, or red, or orange, or yellow, or brown, or white, or purple, or even blue! These colors help the frogfish mimic corals, sponges, algaes, or even rocks. Often a trusting fish become prey all too easily as they go to hide in the ‘coral’ or ‘rock’ only to then get eaten by the frogfish that has transformed . Frogfish gobble up their prey in 6 milliseconds. Frogfish actually have the fastest mouth in the sea. Their mouth is able to expand 12 times its size and they can easily eat prey 25 percent longer. They’re opportunistic and eat whenever possible. They tend to feast on smaller fish, crustaceans, or even other frogfish!
Another amazing mechanism of the frogfish is an antenna that dangles from their head. They’ll mimic the actions of a smaller animal (e.g., a worm or shrimp) with this antenna so that their own prey will swim right up to them. Don’t worry though, the lure will regenerate if eaten.
Frogfish do not have a swim bladder, but do have modified pectoral fins enabling them to ‘walk’ along the seafloor. See the video below to see this in action.
Frogfish live in the tropical and subtropical areas in the Atlantic, Indian, and Pacific Oceans.
It is the original footage from these hairy frog fish walking on the sand was made by Daan van Wijk in Indonesia. These scenes are from the movie Impressionesia”.
