Lemmings are small rodents who live throughout the arctic in tundra or boggy habitats. They are four or five inches long, with a short tail, furry feet, and small ears.
A European species of lemmings is famous for making devastating migrations in enormous numbers at long and irregular intervals.
You could say that lemmings “stampede.” Without the hoofbeats. Whales stampede, too. No hoofbeats either.
Lemmings are “homebodies”...they tend to stay close to their burrows and take care of their offspring.
Lemmings produce four times as many females as males.
The main ingredient in the arctic fox’s diet is lemmings. The more they eat, the more little foxes there’ll be in a litter.
The collared lemming is the only true rodent that turns white in the winter.
Baby lemmings are born under the snow and drink their mother’s milk to survive.
Each female may have up to 3 litters a year with an average of 4 and one half young per litter.
Lemmings have smaller ears and tails than other rodents. Less surface area reduces heat loss. That means there is less skin area for heat to escape from.
A month after lemmings are born, they are ready to mate. Few lemmings live over a year.
It has been a common belief in southern Asia that a tiger’s ears are so sensitive that they can hear the whistling of a man’s breath through his nose hairs. So hunters keep their nostrils barbered.
