 GEDC0113 Outer Reef
Outer Reef is part of the reef that faces the open ocean. This is where most of the popular dive sites are located. It is where the dynamic elements of the reef comes to life bringing a whole host of spectacular images that for a long time have mesmerized divers from all over the world.At the Palau Aquarium, a 5,500 gallon tank live miniturized version of the outer reef has been created with variety of corals, soft corals and fish giving just a scale of the real thing.
 Palau Islands
Surrounded by the warm tropical waters of the Western Pacific with close proximity to the Asian sub-continent, the islands of Palau have the most diverse marine flora and fauna found anywhere in Micronesia. Palau, compared to other islands of volcanic origin, has the richest and the most diverse of marine organisms.
 exhibits1  Palau’s Topography
A visit to the aquarium will find a visitor poring over a detail of fine craftsmanship work as evident by the topographical map of the Palau Islands.
 exhibits2 Mangroves
Observe the long tentacle-like roots that emerge from the sides of the trees trunks and branches hanging down to reach the water. Catch a glimpse of the school of archerfish that readily spits out beads of water to hunt down food. Bring yourself down without getting wet, to see the upside-down jellyfish, ever pulsating on the muddy bottom of the mangrove forests.
 exhibits3 The seagrass bed
The next stop on your journey is the sea grass bed. Where else can you see schools of rabbit fish feeding without putting on a mask and a snorkel? This exhibit’s only rival is the natural habitat. The seagrass aquarium gives you a chance to see how the animals and plants interact. Spend some time and allow yourself to catch a glimpse of the inner workings of this habitat.
This interactive Touch Tank, our newest exhibit, is a fun, interactive way for children and adults to learn about marine invertebrates, such as sea cucumber and blue starfish. These invertebrates are safe to handle, and they each have a distinct texture—from slimy and slippery to coarse and dry. The Touch Tank Exhibit is located near picnic gazebos, and Palau Aquarium encourages families to visit, relax, and enjoy!
 exhibits4  The inner reef
An aquarium visit is never complete without seeing big fish. The Inner Reef aquarium is home to one of the trademarks of the reef areas – the large napoleon wrasse. A view of the water surface from the sides of the aquarium, any sport fisherman would be tempted to grab the giant trevally by the tail as it swiftly swims by. The white-tip reef shark, green turtle, giant grouper, eel and much more can be seen in this action-packed tank.
 exhibits5 The reef crest
Palau is famed around the world for its clear waters and its gorgeous diversity of corals. The Reef Crest exhibit testifies to the fact that Palau is indeed the world’s underwater “Garden of Eden.” Never before has anyone seen so many of the beautiful, specially selected species of coral (polyps) feeding butterfly fish along with the envied collection of corals ever put together inside one tank. The Reef crest is a “must see” for all enthusiasts.
 exhibits6  Marine Lake
Palau Aquarium has created the only exhibit in the world to display the lakes distinctive and famous residents – the golden Mastigia jellyfishes. Nowhere in the world can you see these unique and delicate creatures that have lost their ability to sting.
 exhibits7 Camouflage
The journey then takes you indoors where you will be fascinated by many rare, colorful, and exotic creatures. They are creatures from as close as the next seagrass area, and as far down where no light exists, and the inhabitants of areas with strong waves, rippling currents and constant surge action.
 exhibits8 The Deep Drop-Off
Amazing, rare, and deep-water creatures are showcased in these themed “Creatures of the Dark and the Deep” exhibits.

 exhibits9 The Palau Nautilus
Witness a “living fossil,” the endemic Palau nautilus, and be mesmerized by the shape and the special characteristics exhibited by these ancient animals that prowl in the deep, dark ocean.
The Overhang
A reef overhang is a place protected by the shade and teeming with beautiful fish that spend almost all their lives swimming upside down, and the colorful soft corals dangling downward. This exhibit brings you to a place where no one but divers have ever been.
Cave Creatures
They spook you with their bioluminescent features. Venturing out only during the night, these flashlight fish possess a luminous organ that produces light biochemically by bacteria that live within the light organ. A must see exhibition! Evolution never ceases to amaze
exhibits10 Symbiosis
The Symbiosis Exhibit is divided into three small habitats that entertain as well as nurture the roles and interaction of the animals in our delicate marine ecosystem.
