Scientists exploring the ocean floor in Antarctica have found a larger group of fish nests than ever before. The discovery came 1． a surprise, and it will help scientists develop a more complete idea of the ocean food web in the area.

In the south Weddell Sea, not far from Antarctica’s Filchner Ice Shelf, scientists were2． (amaze) to discover a group of about 60 million icefish nests on the ocean floor. Before this, the 3． (large) group of icefish nests that had ever been found includes less than 60 nests. Lilian Boehringer, a research student, was the first 4． (discover) the nests. “They were everywhere,” she told The New York Times.

The researchers used a special device called OFOBS to make two more four-hour “dives” ,5． (try) to discover the limits of the nesting area. The nests scientists found were in the shape of 6． circle. Each nest held about 1,700 eggs. Usually, Weddell seals (海豹)7． (spot) in the waters above the nesting site. Trackers 8． (fix) on some Weddell seals show that they dive all the way to the sea floor.

The team placed a camera on the sea floor before leaving, 9． will take a picture of the nests in the area 10． (two) a day for the next two years. They hope the pictures from this camera will help them learn more about the lives of the icefish.
