Shark Attack!

Back in 1975, the Steven Spielberg’s “Jaws” movie became one of the most successful motion pictures of all time. Leveraging on the people’s ancestral fear of big predators, one of the main results of the movie has been keeping millions of people out of the water, printing in the general audience’s mind the idea that sharks are cold-blooded assassins and that...

More Harm than Good?

An important project for the island of Lembongan is likely to lead to more harm than good. The deployment of a submarine electricity cable from Bali has resulted in various accidents, seriously damaging the pristine and precious coral reefs of the island. This is another example of infrastructure developed without any attention to the environment. A submarine cable...

The Biorock Project: Coral Reef Restoration in Pemuteran (North Bali)

One of the biggest issues in modern Indonesia is the deterioration of coastal coral reefs, due to many factors like coastal erosion, illegal bombing or cyanide fishing, chemical pollution and so on.

The traditional fish market of Jimbaran and a sustainable seafood choice

Every visit to a ‘Pasar Ikan’ (fish market) in Indonesia can be an unforgettable experience.

A White House for Anemonefish

Coral bleaching is a natural phenomenon of zooxanthellae (the symbiotic algae necessary for the survival of many hard and soft corals) expulsion that some corals and anemones realize in presence of high temperature, which induces the production of toxins by their symbiotic “allied”. In this case, the enemy comes from inside and should be eliminated, and the animal...

Do we really need “artistic” underwater photography?
