The twisting and curling lianas are part of many sceneries in rain forests. Lianas are climbing, or I should say creeping woody vines. They belong to the group of plants called epiphytes that grow on other plants. Some of them, may be as long as 1000 m. and thick as my torso. Lianas can secure some trees against falling but as well may pull when a heavier tree is falling. Lianas constitute a great natural walkways and bridges between the trees for many arboreal animals.
