Part 2/9:
Behrend’s expedition begins in Greece, where he partners with Alexandros Frantzis, a leading expert on sperm whales. Their primary goal is to unveil the secret lives of sperm whales in the Mediterranean. Despite skepticism from people who think sperm whales are found only in more expansive oceans, Frantzis reassures Behrend that there are indeed sperm whales in the Mediterranean, particularly along the Hellenic trench.
As they launch the research vessel Nereis into the deep blue waters, the team prepares for the task ahead, which involves using hydrophones to listen for the distinctive clicks made by sperm whales—a crucial part of their communication and navigation.
