Scientists discover amazing Antarctic giants

Although scientists expected to find a greater diversity of fish, instead they were surprised to find marine organisms they had never seen before, as if time stood still here for some of them and they've managed to keep impressive sizes. Scientists explained the size through the conditions offered by the water they live in (low temperature, few predators, plenty of oxygen). According to the National Institute of Water & Atmospheric Research (NIWA), at least 8 new species of mollusks have been discovered.
