Piranhas have overlapping, small, and tough scales that provide protection against predators and environmental hazards. This scale structure helps reduce water resistance, aiding in their agility while swimming. Additionally, their scales can reflect light, which may assist in camouflage or communication among members of their species. Overall, the design of piranha scales is an adaptation that enhances their survival in their riverine habitats.
