The ship's bottom is covered with coral and other marine life, especially stony coral. There are lots of fish swimming around. We ended up playing around with an octopus for a while, too. They change colors rapidly, it's really amazing to see. Inside the ship's holds, or the oil tanks, there are what look like miles of pipe and many valves that were used to transfer the oil between holds. The holds are big and since the ship is overturned, they're very dark.
