Fiddler ray (Trygonorhina fasciata), partly hidden in seagrass debris on the sandy floor. The water was about 4 m deep.
As the seagrass debris moved in the current, more of the fish's body became visible.
The fish's head and pectoral fins fuse to form a large flattened disc. Probably because of it's large round head and a long tail, it gets to be a member of the guitarfish family : )
The large dorsal fins on the fish's tail.
