In Madagascar’s remote western desert, divers explore a hidden pool of water. Over 160 feet below the surface, this incredible underworld opens to over seven miles of connected tunnels and some of the largest underwater chambers in the world. Within these caves lies a graveyard carrying remains of now-extinct animals in Madagascar, including a lemur that once grew to the size of a gorilla.
