Shadow Sharks

Shadow Sharks
The sixgill shark is a primitive-looking giant that is rarely encountered by divers. For wildlife filmmaker Natali Tesche-Ricciardi, finding this elusive shark is an ultimate challenge. Her search is made all the more difficult by the dangers of the Mediterranean's treacherous Messina Strait - a narrow channel of water where sixgills are sometimes seen but rarely studied. Using state-of-the-art ROV and submarine technology, Natali enters the depths of the Messina Straits.
