Science writer and video blogger Sébastien Moro joins host Luisa Rodriguez to talk about the latest research on fish consciousness, intelligence, and potential sentience.
They cover:
• The insane capabilities of fish in tests of memory, learning, and problem-solving.
• Examples of fish that can beat primates on cognitive tests and recognise individual human faces.
• Fishes’ social lives, including pair bonding, “personalities,” cooperation, and cultural transmission.
• Whether fish can experience emotions, and how this is even studied.
• The wild evolutionary innovations of fish, who adapted to thrive in diverse environments from mangroves to the deep sea.
• How some fish have sensory capabilities we can’t even really fathom — like “seeing” electrical fields and colours we can’t perceive.
• Ethical issues raised by evidence that fish may be conscious and experience suffering.
• And plenty more.
