TED-Ed: How smart are dolphins? - Lori Marino

Dolphins are highly intelligent aquatic mammals known for their complex social structures, communication skills, and cognitive abilities. They evolved from land mammals and adapted to ocean life with advanced brains and echolocation. Dolphins exhibit cultural transmission, tool use, and language comprehension, demonstrating self-awareness and metacognition. Their empathy and altruism extend to humans, raising ethical questions about their treatment. The video explores these aspects, emphasizing the need for conservation and empathy towards dolphins.
