Oceans cover more than two thirds of the earth's surface, and they are very deep! Fish and other animals make their homes in all different parts of the ocean, even on the bottom, or sea floor. The ocean is also filled with lots of plants, which provide food, homes, and protection for ocean animals. A person who studies ocean life is called a marine biologist.
Some animals that have the word "fish" in their names are not really fish. Some examples are cuttlefish (they are mollusks, see below), jellyfish (they are actually plankton), and starfish (they belong to a group called "echinoderms"). Can you think of any other animals that are called fish but do not have the things it takes to be a real fish?
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!
The aquatic displays and hands-on touch tanks at aquariums introduce children and parents to our local marine flora and fauna. Outreach programs are developed and presented by our marine staff and focus on place-based experiences and a hands-on approach to learning.
