Answer:
External Fish Anatomy
Fins:
Fins are appendages used by the fish to maintain position, move, steer and stop.
Scales
Scales in most bony fish -- most freshwater fish other than gar that have ganoid scales, and catfish which have no scales -- are either ctenoid or cycloid.
Gills
The gills are the breathing apparatus of fish and are highly vascularized, which gives them their bright red color.
Eyes
Fish can detect color.
Nares
Paired nostrils, or nares, in fish are used to detect odors in water and can be quite sensitive.
Mouth
The mouth’s shape is a good clue to what fish eat.
Lateral Line
The lateral line is a sensory organ consisting of fluid filled sacs with hair-like sensory apparatus that are open to the water through a series of pores, creating a line along the side of the fish.
Vent
The vent is the external opening to digestive urinary and reproductive tracts.
Internal Fish Anatomy
Spine
The primary structural framework, upon which the fish's body is built, connects to the skull at the front of the fish and to the tail at the rear.
Spinal cord
Connects the brain to the rest of the body and relays sensory information from the body to the brain, as well as instructions from the brain to the rest of the body.
Brain
This is the control center of the fish, where both automatic functions, such as respiration, and higher behaviors occur.
Lateral line
One of the fish's primary sense organs, this detects underwater vibrations and is capable of determining the direction of their source.
Swim (or air) bladder
This hollow, gas-filled balance organ allows a fish to conserve energy by maintaining neutral buoyancy (suspending) in water.
Gills
Allow a fish to breathe underwater.
Kidney
This filters liquid waste materials from the blood, and these wastes are then passed out of the body.
Stomach and intestines
These break down food and absorb nutrients.
Pyloric caeca
This organ with fingerlike projections is located near the junction of the stomach and the intestines.
Vent
This is the site of waste elimination from the fish's body.
Liver
This important organ has a number of functions.
Heart
This circulates blood throughout the body.
Gonads (reproductive organs)
In adult female bass, the bright orange mass of eggs is unmistakable during the spawning season, but is still usually identifiable at other times of the year.
Muscles
Provide movement and locomotion.
