Jungle vines are an important part of the tropical rainforest ecosystem. They are typically woody, climbing plants that grow on trees and other vegetation. Lianas (6 letters) and lianes (6 letters) are two types of jungle vines. Lianas are thick, woody vines that can reach up to hundreds of feet in length and are often used by animals to move through the canopy of the rainforest. Lianes are thinner, more flexible vines that are used for support and to help plants climb. Both types of vines are essential for the health of the rainforest and its inhabitants.
