Colours of the Mediterranean Sea

Deep sea has an intense blue color. The light that penetrates the water changes its light intensity and its spectral composition by effect of  selective absorption by water of the different wavelengths that make up the visible spectrum.

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.
