Glacier mice

[2] Although what preconditions are necessary for glacier mice to form has yet to be determined, they have been observed in Alaska, Chile, Greenland, Iceland, Svalbard, Uganda and Venezuela, as well as several Subantarctic islands.

[3][4][5] In at least some cases, glacier mice apparently reproduce asexually due to the effect of the harsh glacier environment on traditional moss reproduction strategies.

[6] Glacier mice are notable for their movement across the ice, which appears to be non-random, taking the form of herd-like behavior.

This movement is as yet unexplained,[1] and does not appear to be solely the product of wind or the direction of a slope.

[7] The use of accelerometers has demonstrated that glacier mice do in fact rotate and roll, rather than simply sliding across the ice, over time exposing all of their surfaces.
