Shark

There are multiple sharks in each reef. They are generally passive, unless you are spearing fish. This leaves a trail of blood that attracts the sharks. A shark will eat a fish off the end of your spear. **warning* in the current version of the game, when this happens you take damage, but there is no visible or audible cue that you did. Check your watch to see your health. ** If the sharks are far away you can usually spear 3-5 fish before it becomes a problem. They will not continue to attack you if you stop spearing fish.
