Centella Cave is a limestone cave located withinAnkarana National Park in northernMadagascar. It forms part of the extensive karst system of the Ankarana Massif, a Jurassic limestone plateau characterized by sharp limestone pinnacles known astsingy, underground rivers, sinkholes, and complex cave networks.[1][2]
The cave is one of numerous subterranean features within the Ankarana karst, which has been mapped and studied for its geomorphology and biodiversity.[3]
Centella Cave is situated within the Ankarana limestone massif, which dates to the Middle Jurassic period. The massif developed through tectonic uplift followed by prolonged chemical weathering and erosion, producing a mature tropical karst landscape.[3]
The cave system exhibits typical speleothems such as stalactites and stalagmites, along with vertical shafts and subterranean waterways. Underground rivers contribute to ongoing speleogenesis and groundwater circulation within the massif.[1]
The caves of Ankarana, including Centella Cave, support specialized fauna adapted to subterranean environments. Documented cave-associated species in the massif include several bat taxa and the blind cave-dwelling fishGlossogobius ankaranensis.[4][5]
The broader Ankarana region is recognized for high levels of endemism and ecological sensitivity.[1]
Centella Cave is accessible through guided excursions organized within Ankarana National Park. The park is managed by Madagascar National Parks and promotes regulated ecotourism to protect fragile karst ecosystems.[6] The dry season (May–October) is generally considered the most suitable period for cave visits due to improved accessibility.
