Strangler figs are a fascinating group of plants found in many tropical forests. These plants share a common "strangling" growth habit, an adaptation that allows them to thrive in the dark understory where competition for light is intense.
These unique plants are hemiepiphytes, meaning they spend the first part of their lives without rooting into the ground. Their seeds, often dispersed by birds, germinate in crevices atop other trees.

Ficus craterostoma: A Notable Species
Ficus craterostoma, a species of strangler fig, is a fig shrub or tree of the Afrotropics that may grow up to 20 m tall. It is found in lowland tropical and swamp forests in the west, or in afromontane forests, including rocky situations, along Africa's eastern escarpments.
The leaves of F. craterostoma are dark and small, obovate to blunt-tipped (reverse triangular) or even concave at the tip. The small, stalkless figs grow in pairs in leaf axils.

Adaptations and Symbiotic Relationships
Strangler figs have developed remarkable adaptations to survive in the challenging environment of tropical forests. Their hemiepiphytic lifestyle allows them to reach for sunlight without the need to compete for ground-level resources.
Recent research suggests that strangler figs may even support their host trees during severe storms, showcasing a potential symbiotic relationship.
These all share a common "strangling" growth habit that is found in many tropical forest species. This growth habit is an adaptation for growing in dark forests where the competition for light is intense.
