A five-minute boat ride from Koror lies this mysterious and fascinating shipwreck. The coastal freighter Chuyo Maru was bombed in April 1944 and sits upright on a sandy seabed between 11m and 40m. The entire ship supports all sorts of fish life, including numerous lionfish, and is overgrown with soft and hard species of coral. Look for the large anchor winch, stern gun, ammunition boxes, coils of cable, as well as the remains of the brass compass and the ship's telegraph.

The tops of the masts (crosstrees) are heavily encrusted with corals and delicate sponges of every hue and texture, attracting a host of small, colourful species.
