Fish are aquatic, ectothermic vertebrates. Many structures in fish are adaptations for their aquatic lifestyle. For example, fish have a stream-lined body that reduces water resistance while swimming. Fish have gills for “breathing” oxygen in water and fins for propelling and steering their body through water.
