The Twin Caves are a location in the Zahhab Region Depths in Endless Ocean 2. As the name of this location suggests, they are a pair of caves situated right next to each other on the Eastern side of the South Crevasse. An aggressive Bluntnose Sixgill Shark that patrols the area makes its territory known by attacking encroaching divers, so it is advised for players exploring this area to take extra care in observing their surroundings.
