important of planarians
Planarians exhibit a behavior known as phototaxis, where they move away from light sources. This response is critical for their survival as it helps them avoid potential predators and harsh environmental conditions associated with bright light. By seeking dark, moist environments, planarians can maintain their habitat, conserve moisture, and enhance their chances of survival and reproduction. This adaptive behavior underscores the importance of sensory responses in the evolutionary success of organisms.
