That’s because the ice nearby has been melted, while the ice beneath the moss ball has been protected from the sun. Study co-author and wildlife biologist Sophie Gilbert told NPR that they noticed the balls were in slightly different spots every day. This video is unavailable. Surprisingly, the dominant moss ball movement direction does not align with the prevailing wind or downslope directions, nor with the dominant direction of solar radiation. The mice travel about one inch (2.5 centimeters) a day.

That list now includes on frozen glaciers in Alaska, where researchers looking for microbes – long assumed to be the only things that can survive in the harsh environment – have been finding the ice mysteriously covered with small, green mice moving around in formation on the surface … so many of them that the scientists received funding to study them. In the early 1950s, these globular forms of moss were given their playful name by Swedish plant biologists studying Falljokul glacier in Iceland, who came across a large dispersal of these cute rounded clumps, and coined them “Glacier Mice”. They tracked 30 glacier mice by tagging each moss ball with a loop of wire and some beads. Stephen Coulson, Author provided. That was in 2009. Researchers from Swansea University in the United Kingdom working near Greenland's Helheim Glacier spotted a spectacular calving event on July 12, 2010. Use up and down arrows to change selection. Then, from time to time, the moss ball falls off its ice when new ice forms and rolls to a new position. Glacier mice litter the ice surface. Moss balls tumble and move because of the sun. Mice on the move. If the glacier mice stopped rotating, the moss that comes into permanent contact with the glacier … "They're not attached to anything and they're just resting there on ice," he says. It is this rotation that enables the glacier mice to grow moss around the whole of their outer surfaces – sometimes creating near perfect spheres. The scientists stuck thermometers in five glacier mice to monitor their internal temperatures and brought 10 others back to the lab. Bartholomaus told NPR the movement was similar to a school of fish or a flock of birds and defied conventional explanation. Glacier mice can grow to the size of a tennis ball. The first option will be automatically selected. By using this site, you agree to the use of cookies by Flickr and our partners as described in our cookie policy.

Coulson pulled the moss balls apart, hoping to … (Photos here.) The moss wasn’t rolling down a slope, getting pushed by the wind, or following the sun. Glacier mice are soft green ovals, about as big as your hand. Perhaps the movement and moss growth is required to feed their gut microbes. Coulson pulled the moss balls apart, hoping to … But glacier mice are actually balls of moss, each about the size of a tennis ball, and typically shaped into slightly squashed spheres that amass around pebbles on … It seems that no matter where one travels on Earth (Remember traveling? While previous research had established that the glacier mice moved and rolled around – probably so every side could see life-giving sunlight – the new study shows that the clumps actually move together in specific directions.. Not that this movement is particularly fast: the group of 30 glacier mice were recorded as moving at an average of 2.5 centimetres (almost 1 inch) a day. He bravely touched one and found it was a soft, moss-covered ball of dirt. Scientists have known about them since at least the 1950s. Upon finding a lack of information on what these might be, Bartholomaus called them “glacier mice” and decided to study them.
