The Red Squirrel or Eurasian Red Squirrel (Sciurus vulgaris) is common throughout Eurasia. The red squirrel is an arboreal, primarily herbivorous rodent.
The long tail helps the squirrel to balance and steer when jumping from tree to tree and running along branches and may keep the animal warm during sleep. The red squirrel, like most tree squirrels, has sharp, curved claws to enable it to climb and descend broad tree trunks, thin branches, and even house walls. Its strong hind legs enable it to leap gaps between trees. The red squirrel also has the ability to swim.
