There are some injury risks that diving exposes you to. This is dependent on the site. For example, coral reef dives carry the risk of coral cuts, which can take months to heal well, and of stings and bites from poisonous marine life. Educate yourself about risks in particular environments and particular sites and pay attention to dive orientations.

You can dramatically reduce the risk of injury by exercising caution and not interfering with the state of the dive site (e.g. by provoking the marine life or disturbing the bottom); this also helps preserve the site.
