Which tentacles are used for light detection in banana slugs?

Explanation:
Light detection in banana slugs comes from the upper pair of tentacles, which bear eyes at their tips. These eyes are simple photoreceptors that sense light levels (bright vs. dark) rather than forming detailed images. This helps the slug avoid bright light and find shaded, damp areas. The lower pair of tentacles is used for smell and chemical sensing, guiding the slug to food and helping it navigate its surroundings. The tail end isn’t involved in light detection.
