IERAPETRA, Greece: On his fishing boat moored in the Greek port of Ierapetra in southwestern Crete, Alexis Charlambakis pries open the mouth of a freshly-caught pufferfish to reveal two massive teeth on each jaw. “If one of these bites you, it will take your finger clean off,” the 43-year-old said. “They are the destruction of the sea. They leave nothing behind.” Proof of the damage is visible on a neighboring boat deck: a ray, a common seabream and another fish netted that day lie half shredded.
