Positive thigmotaxis is often observed in animals seeking shelter or protection, as staying close to surfaces can reduce exposure to predators and environmental hazards.
When stimulated, these receptors send signals to the nervous system, triggering a motor response that directs the organism's movement.
In invertebrates, specialized sensory organs such as setae (bristle-like structures) or antennae are involved in detecting and responding to tactile stimuli.
Positive thigmotaxis helps animals find and stay in safe, sheltered areas, which can protect them from predators and harsh environmental conditions.
Thigmotactic behavior aids in navigation through complex environments, allowing animals to efficiently find resources and avoid obstacles.
Additionally, researchers use thigmotaxis as a behavioral assay to investigate anxiety, stress, and other psychological states in animal models.
