How to scuba dive safely
There is one simple rule every diver should know and respect - limit the interactions with the marine life ideally to zero contact. Underwater animals and plants have been there for millions of years, while humans have found home on land. As cute as many of them might look, there are several good reasons why we should not touch or harass marine life. Direct interaction might be allowed (or even necessary) only in case of an official scientific research such as tagging certain fish or during rescue activities.
