Mesenchytraeus solifugus is a species of oligochaete worms commonly called ice worms that inhabits coastal glaciers in the North Western portion of North America. M. solifugus is dark brown and grows to about 15 mm long and 0.5 mm wide. They have a high population density and are relatively common in their area. The ice worms are also very sensitive to temperature and can only survive from approximately -7 °C to 5 °C. The ice worm is studied for it’s ability to survive in low temperatures. ce worms have heavy pigment, absorbing all colours or reflecting dark brown; however, they burrow into glaciers to avoid strong sunlight. Carlo Emery named the species solifugus in 1898, meaning "fleeing from the sun".
