Fish Depth Perception - Presentation

Final assignment of the course: "Cognitive and Brain Sciences Seminar".

In this presentation, I explored how fish perceive depth through a combination of sensory systems, including vision, the lateral line, the swim bladder, and nociceptors. I examined how diel vertical migration patterns are influenced by light levels, and how different sensory modalities contribute to navigation, predator avoidance, and buoyancy control. My main conclusion was that while fish integrate multiple sensory inputs, the dominant system varies by species and environment—for example, lateral line cues may dominate in murky waters, whereas vision plays a larger role in clear conditions.
