The speaker discusses the "dark side" of dolphins, claiming that despite their intelligence and friendly nature, they exhibit some disturbing behaviors. He shares three main disadvantages of dolphins: they use drugs, specifically a toxic fish called pufffish, to get high; they engage in harassment, often in groups, and have even been known to attack humans; and they kill their own young, with no clear reason or explanation. The speaker notes that dolphins are highly intelligent and social creatures, but their behavior can be brutal and violent at times.
