The collection of the museum includes over two floors. The ground floor is home to fish tanks of varying sizes that house all manner of marine life. All kinds of fish you would find in the sea area of Khanh Hoa Province are presented there: reef sharks, living coral, turtles, anemones, puffers, lionfish, sea horses, clownfish, and a whole array of colorful reef species, some of which can be found in no other place in the world. Each of them has a label indicating their name and characteristics in Vietnamese and in English. 

The upstair flooor is for exhibiting specimens, local boats and fishing artifacts, plus an 18 metre long whale skeleton. Over its long history, this museum has been holding more than 20000 specimens of tropical marine creatures. Apart from the real fishes, there are also rare species’ skeletons or bodies preserved in formaldehyde solution. There are even finds of endemic species from Kampuchean Vietnamese seas and from other nearby countries, some of which are extremely rare, like the dugong or sea cow. Kids are often very excited to visit the big tropical turtles and crocodiles.

Besides the museum aquariums, there are also many of the theme rooms in the National Oceanographic Museum of Vietnam which focus on marine science featuring the history of its research equipment and technology such as: “From Light to Life” (features algae and phytoplankton), “Life in a Drop of Water” (microscopic aquatic organisms), or rooms illustrating coastal natural disasters, traditions and culture of Vietnam fishing.
