Learn about Marine Life
There are thousands of species of marine life, from tiny zooplankton to enormous whales. Each is adapted to the specific habitat it occupies. Fish can drink salt water, and eliminate the salt through their gills. Seabirds also drink salt water, and the excess salt is eliminated via the nasal, or "salt glands" into the nasal cavity, and then is shaken, or sneezed out by the bird. Whales don't drink salt water, instead getting the water they need from the organisms they eat.
Microscopic plants and animals called plankton are very important in the ocean because they become food for a lot of animals. They drift along with the currents in the water and are eaten by fish, scallops, anemones, and others. Krill are small creatures that look like shrimp. They eat plankton and are eaten by larger animals, such as whales and birds.
Another important dive was the Trieste. The Trieste's first dive was made in 1953. In the years following, the bathyscape was used for a number of oceanographic research projects, including biological observation, and in 1957 she was chartered and later purchased by the U.S. Navy. The Navy continued to use the bathyscape for oceanographic research off the coast of San Diego, and later used the Trieste for a submarine recovery mission off the U.S. east coast. The bathyscape was retired following the U.S. Navy's commission of the Trieste II external, and is currently on exhibit at the Washington Naval Historical Center external.
Because many bioluminescent animals live far down in the oceans where it is very dark (since sunlight cannot travel down that far through the water), the lights they make work sort of like a night light and help them see where they are going and to find food as well as other creatures to mate with. The anglerfish is an example of a deep sea creature that uses bioluminescence to find food. It has a glowing "lure" that extends from its head and dangles above its mouth. Other fish think the lure is food, but when they try to eat it, the anglerfish eats them instead!
Fortunately, thanks to the work of past and present ocean explorers, the public is increasingly aware of these risks which encourage public agencies to take action and promote research. The efforts of public agencies using a multi-disciplinary approach, together with the efforts provided by numerous private marine conservation organizations that work on issues such as advocacy, education, and research, will help drive the momentum needed to face the challenges of preserving the ocean.
