Dragon's Breath Cave
Dragon's Breath Cave is a cave located northwest of Grootfontein in the Otjozondjupa Region of Namibia. It was discovered in 1986 and is named for the moist air rising from its entrance.
The cave contains the world's largest non-subglacial underground lake, with an area of almost. The lake is located around below the surface. Its total depth is unknown, though exploration to date suggests it is at least 100 m. Although it has been reported that the rare fish species, Clarias cavernicola, lives in the lake in the Dragon's Breath Cave, this is an error. It is only known from the nearby Aigamas Cave.
Martyn Farr records in his book "The Darkness Beckons" the exploration of the cave by a team of divers and cavers organised by Charles Maxwell the year after the cave was identified in 1986 by cavers as being of significant size.
