Lemming
* Most lemmings are solitary animals, only coming together to mate
  - three to six inches in length and weigh less than four ounces
  - attract predators
  - die of causes
* Most lemmings have offspring
  - teeth
* Most lemmings live in regions
  - on terrains
  - survive on diets
  - weigh ounces
* Some lemmings cause misfortune
  - defend territory
  - die of diseases
  - eat twigs
  - enter sea
* Some lemmings have ability
  - fur
  - stumps
  - tails
  - inhabit slopes
  - survive on vegetation
* also have sharp little teeth which helps the lemmings to gnaw through tangles of roots.
* are able to reproduce less than a month after being born.
* are active all year
  - during both the day and the night
  - also active
  - another food source for the Arctic fox
* are found in Arctic and subarctic regions of North America, Europe and Asia
  - only in the Northern Hemisphere
  - herbivores with a main diet of moss and grass
  - herbivorous heterotrophs and eat plants that grow in the tundra in northern Alaska
  - important animals in their ecosystems
  - little, furry animals with short, skinny, furry tails
  - mammals, thus they always have the same body heat
  - mouselike rodents that live in treeless areas of northern Canada
  - one of the only true Arctic rodents, and they prefer to reproduce in winter
  - probably their most favoured prey
  - quite rounded in shape with brown and black long, soft fur
  - seen flying into the water
* are small beetles that only eat plants
  - creatures who do what they're directed to do
  - mouse-like animals that live in the tundra
  - rodents related to muskrats
* are small rodents that feed on plants
  - look like guinea pigs
  - with an unusual reputation
  - small, furry animals with short tails and long whiskers
  - smalls
  - surprisingly solitary animals , only coming together to mate then separating again
  - the staple food for Arctic foxes
  - video games
* belong to the rodents.
* can also explode.
* commit mass suicide by jumping off cliffs
* dive from a cliff.
* eat willows and herbaceous plants.
* exhibit both diurnal and nocturnal active, often active both night and day.
* fall at constant velocity but are destroyed if they fall from too great a height.
* feed mainly on leaves, grasses, shoots and bulbs, occasionally storing food for winter use.
* get an urge to move when local conditions become too crowded.
* have a large number of predators
  - very short tail, a stubby, hairy snout, short legs and small ears
  - long claws on their forefeet and sharp teeth for gnawing roots
  - plasma membranes
  - rib cages
  - vertebrate feet
* live in Arctic and subarctic regions
  - colonies and dig burrows in the snow
  - some of the coldest environments on the planet
* make nests out of grasses, feathers and musk ox wool
  - paths through the grass, under roots or under snow, called runways
* migrate in summer
  - sporadically every few years when their population explosion
* move to the right or left and sometimes climb.
* never think about why they jump off cliffs.
* occupy areas.
* play a large and significant role in their ecosystems
  - similar role wherever they are found
* prefer high cliffs.
* search for food.
* sometimes have population booms.
* spend most of their lives alone, only coming together to mate.
  - the cold primarily for two reasons
* tend to be aggressive toward one another.
* vary in colour.
+ Lemming, Life: Rodents
  * Many lemmings leave to find a new home, when they run out of food and space. Soon, millions of lemmings decide to follow the crowd. They go across the Arctic as a huge mass. Foxes and owls kill many of them. Some drown when trying to swim across rivers.
