What are the specialized cells in fish?

Specialized cells in fish include neurons for sensory perception, such as those in the lateral line system, which detect water movement and vibrations. Epithelial cells in the gills facilitate gas exchange, allowing for oxygen uptake and carbon dioxide release. Additionally, specialized cells in the skin, like chromatophores, control pigmentation and help with camouflage or signaling. Muscle cells are also specialized for efficient swimming, with red and white muscle fibers adapted for different types of activity.
