Snake
The movement of snakes in trees has only recently been studied. While on tree branches, snakes use several modes of moving depending on species and bark texture. In general, snakes will use a modified form of concertina moving on smooth branches, but will laterally undulate if contact points are available. Snakes move faster on small branches and when contact points are present, in contrast to limbed animals, which do better on large branches with little 'clutter'.
