Blue Corner, together with Jellyfish Lake, is one of the most amazing dive sites in the world. The reefs of Palau are at a convergent point of where three major currents meet. They are home to over 1,500 fish species, and over 700 species of coral and sea anemone.
Blue Corner is an amazing wall dive and contains many of these different species of marine life. It is most famous though, for the large big fish and divers can see many larger species all on the same dive. It is remarkable for this reason; it is hard to find a dive site in the world that matches Blue Corner for the sheer volume of larger fish, and even experienced divers will be left in complete awe at the amount of fish they will see.
The site is a channel and so has strong currents making it a dive for more experienced divers. Normally divers hook onto the reef to then watch the big fish as they swim by. There can be large schools of fish, alongside Green and Hawksbill turtles, eagle rays, manta rays, sailfish, and many sharks come to feed in the area. Other big fish include snappers, Napoleon wrasse, chevron barracuda, jacks, and tuna. Wahoo along with red-toothed triggerfish are in large numbers as well. Whale sharks and hammerhead sharks are also common in the area
The wall also has an abundance of soft corals on the plateau of the wall where divers will find smaller reef fish such as butterfly fish, Moorish idols, red-toothed triggerfish, and other common fish. Whilst these can all be seen, most divers stay for longer than a day to dive this site to try to see as many fish species and marine life as possible. Staying longer improves your chances of seeing the less common species such as sperm whales and killer whales and this is highly recommended.
