The Deep Grand Reef is a large cave system located beneath the Grand Reef, featuring many hydrothermal vents.
It is accessed by cracks or holes found in the Grand Reef and is considerably more dangerous than it. The Cyclops could navigate it, albeit limited by the rock formations.
Description
Though it lacks the Membrain Trees found in the Grand Reef, it shares the same Anchor Pods. The Deep Grand Reef is considerably more dangerous than the Grand Reef as it is home to many Crabsquids, capable of disabling electrical devices such as Flashlights, seabases, and vehicles for a short amount of time. Crabsquids are also noted by the PDA as an “unusual energy signature”.
