Which sensory organ do Pictus Catfish use extensively to locate food near the substrate?
Answer
Their barbels
Pictus Catfish rely heavily on their barbels as a primary sensory tool, especially given the murky or darker waters they inhabit in the wild. These fleshy, whisker-like organs are equipped with chemical receptors that allow the fish to 'taste' and sense objects in close proximity, essentially allowing them to feel their way around and locate food items resting on or near the bottom substrate. This adaptation is crucial for their foraging success when light levels drop, making the barbels indispensable for finding food that may not be visible.
