Communication and Perception
Olfaction, vision, and motion detection via the lateral line system help zebrafish perceive their local environment and evade potential predators. Movement in the surrounding water is detected by the lateral line, which can detect small changes in pressure in the immediate environment. Zebrafish respond to a broad range of chemical cues detected by the olfactory bulb. Olfaction is particularly important for reproduction in zebrafish. Female zebrafish must come in contact with male gonadal pheromones in order to ovulate. Meanwhile, male zebrafish must come in contact with female pheromones in order to initiate spawning behavior.
Communication Channels: chemical
