Anjanamba is the name of a cave in South-Western Madagascar, Atsimo-Andrefana region, in the Mikea Forest. It is a fully submerged cave system that has been explored to more than 10km (in 2019) using cave diving techniques. It is the longest underwater cave of Africa.[1]

The cave was first described by Jean-Noël Salomon in 1987 in his PHD Thesis, as a vertical shaft giving access to the water table. He reports the name Ampanonga.[2]

In 2016, Ryan Dart (Madagascar Cave Diving Association) and Phillip Lehman (Dominican Republic Speleological Society) rediscovered the entrance and started the underwater explorations. Gathering a team of cave divers, 4 expeditions have been conducted in the cave and more than 10km of flooded passages have been explored and mapped.[1]

Three short films have been produced on the explorations, titled Spirits of the Cave.[3]

The cave hosts cavefish[2] of the genus Typhleotris[4]
