what do the dorsal and anal fins do for a fish

I call it a sketch of a fish's fin. I am sorry if this does not help, but unless there is a fancy name for it I'm pretty sure its a sketch of a fish's fin. Answer: I call it a sketch of a fish's fin too but on my math hw thing it says u call it a scale drawing. how dumb is that?
The pelvic fin is in the bottom; toward the front side of the middle. The pectoral fin is on the bottom, in the front. The pectoral fin helps control the direction the perch moves. The pelvic fin also controls the direction it moves. The anal fin is in the bottom back side and helps the fish balance. The dorsal fins are on top, one in the middle one it the back and stabalize the fish and aid in sharp turns. The caudal fin, or the tail, is in the back and helps to propel the fish through the water.
Look at the fish's bottom side. If the "anal fin" is fan shaped the fish is a female, if the fin is thin and pointed like a nozzle then the fish is a male. In the male this fin is called a 'gonopodium'
A fish has several different types of fins. There are the pectoral fins, located beneath the operculum (gills). There is the pelvic fin, located at the bottom of the fish, below the pectoral fin. There is the anal fin, which i located behind the anus, and there is the dorsal fin as well. It is located on top of the fish.
The anal fin is the one just in front of the fishes anus.
If you look at there bottom fin the males have a fin that sticks strait back where females are fan shaped.
That is almost all fish, but maybe you are thinking of a sun fish (mola mola) in particular.
The Snakehead fish is a freshwater predatory fish. it is native to Africa and Asia. They can be distinguished from other fish by being very long with a long fin on the top and slightly shorter fin on the bottom.
On a dolphin and most fish the fin behind the dorsal fin is the tail fin. Some fish, such as knife fish, have no dorsal fin or tail fin. Dolphins of course are mammals, not fish.
A female usually has a fan shaped anal fin( anal fin is on the bottom of the fish), and a male's anal fin is pointy, or "rod shaped".
The tail fin of a fish (the caudal fin) is a fish's means of propulsion through the water.
Dorsal - Top of the fish Caudal - The "tail fin" Anal - Rear most fin on the bottom of the body Pelvic - Front set of finds on the bottom of the body Pectoral - Right behind the gills on the side of the fish's body
The fin on the top/back of all fish is called the "Dorsal Fin."
