What are the functions of fish?
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.

What are the internal parts of fish?
Internal Anatomy: The internal organs of the fish perform the basic function of the body such as respiration, digestion, and sensory function. The brain, stomach, liver, and kidneys are same as in man for the fish and perform the same function. Some organs are different; man has lungs to breathe whereas fish has gills for the same purpose.
