Peltodoris atromaculata Reproduction

When we explore our underwater reefs we are often amazed by the number of species that we find in a few square meters and as in this case even in a few square centimeters. We have said it many times that biodiversity makes a habitat and an ecosystem more stable, solid and long-lasting. Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know and recognize them all.

This video was made on the island of Redang in Malaysia during a boat trip to go to the famous Turtle Sanctuary: in fact, in certain periods of the year many turtles reach this location to lay their eggs. They have thus also become a tourist attraction and are so used to the presence of man that they allow themselves to be approached very easily.

Zero visibility - Basket star - Astrospartus mediterraneus

When we dive at depths greater than 40 meters and far from the coast, about 7.5 nautical miles, it is difficult to make predictions about sea conditions such as currents, presence of fish and marine organisms but above all visibility on the bottom. If weather forecasts are now reliable and safe over 24/48 hours, it is practically impossible to predict what will be found on the bottom once immersed.
