“When looking at a coral reef, we are fascinated by the enormous variety of forms of animal and plant life that inhabit it. However, paradoxically for this life that is apparently inexhaustible, it is difficult to understand that everything depends on a fragile superficial layer of microscopic organisms, the madrepore polyps that multiply constantly, never stopping, indefatigably building their limy skeletons on which other madrepore polyps will grow, or where other living creatures will find food and shelter, in the eternal battle for survival”.
Angelo Mojetta, marine biologist
