Researchers explored seven areas of ecological interest and found critically endangered bamboo corals (pictured), tree corals, and black corals that were full of shark eggs. Also documented were a species of sea star (Zoroaster fulgens) never before seen in the Mediterranean and a fish species (Gobius kolombatovici) that was previously believed to only occur in the northern Adriatic Sea
