Located inside Universiti Malaysia Sabah. Have nine aquarium which contains large and small fish, turtle, sharks and etc. There also have mini theatre for video educational purposes. This aquarium is a non profitable facility by the Borneo Marine Research Institute. Despite having a rather small size, the museum do have plenty to offer. Seeing the green turtle swimming happily in the tank is how most marine science students of the university spend their time between classes as it is very calming.
