Most live at the bottom of the Atlantic and Antarctic Oceans, sometimes as far as a mile below the surface. The bottom of the ocean that is slimy is called a biogenous bottom. Transform boundaries are faults that connect two areas where plates are converging or diverging. Biogenous material is the sediment made up of the hard parts of sea animals that accumulate on the bottom of the ocean. The slender snipe eel, one of the most compact deep-sea critters, can grow to a minimum length of four feet, but weighs no more than six or seven ounces. Today, ships equipped with multibeam echo sounders are the primary method of gathering this information, although hydrographers use many other technologies as well. These maps show for the first time the course of ancient ice masses. Oceanographers aboard the HMS Challenger collected the first specimen of the species in 1873, which was the last time one was ever seen. By Casey Williams. The Floors of the Ocean, 1959.
