Aerial roots that may eventually give structural support

All these vines have a strangling habit which is very common in tropical forests.^[1] This is an adaptation for growing in dark forests where the competition for light is intense. Strangler figs suck up the nutrients from its victims, causing them to die eventually.

One usually thinks that seeds start on or in the ground and grow upwards. Figs do it the other way round. Birds drop their seeds into the tops of trees, and the parasitic fig plant grows downwards, eventually round the whole tree. If not already at the top, they also grow upward to reach into the sunlight zone above the canopy.^[2][3]
