On this dive, we leave the mobulas behind and head down along the wall-break described above, as we move to even deeper water. We will explore sheer vertical sections of the wall, as well as ledges, overhangs and steep sandy slopes.
At these depths there is no penetration of sunlight. The fish, corals and fauna are unique and adapted to life in complete darkness. We have found exciting species of fishes here, including the ancient-looking jello-nose fish (Guentherus altivela), the goosefish, and a few as-of-yet unidentified species.
One highlight of our exploration around Cocos at great depth is an encounter with an almost mythical deep-water shark known as the prickly shark (Achinorhinus cookie). We have come upon this shark at depths from 800 down to 1,200 feet (250 to 400 meters).
Dive duration is between 2 and 2.5 hours.
