Glacial Copepods Glaciella yalensis (Copepoda: Harpacticoida)

The glacial copepods are common species on Himalayan glaciers. This has been found on glaciers in Langang, Hidden Valley, Solu-Khumbu region in Nepal. However, they don't exist on other glaciers than Himalayas. Their size is about 1 mm. If you try to see the ice surface carefully, you might find that small red dots are moving on the ice surface. They tend to appear on glacial surface in the night time, when running melt water become less on glacial surface.
