For stability
what do the dorsal and anal fins do for a fish
I guess you mean "Anal fin". If so, the answer is "yes fish do have an anal fin."
The anal fin is the one just in front of the fishes anus.
It's the fin closest to the butt.
The caudal fin, commonly known as the tail fin, is located at the rear of a fish and is primarily responsible for propulsion and steering in the water. In contrast, the anal fin is situated on the underside of the fish, near the tail, and primarily helps with stability and balance during swimming. While both fins aid in maneuverability, their functions and positions on the fish's body differ significantly.
Behind the anal fin.
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 one closest to the bum.
Yes, it is the fin on the ventral surface of the fish between the anus and the caudal peduncle.
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 used to stabilize the fish while it is swimming.in some fishes such as trigger fishes.anal fin is used in sculling.in some live-bearinf fish,the anal fin of male is modified into a gonopodium.
A fish's fins have many functions. Fish have several fins, and what they do with them depends on their species. Some fins are used purely for decoration or to attract a mate, but most have more practical functions. Generally, the fish's tail (caudal fin) is used for propulsion and steering.The dorsal fin can be used to control height in the water and steering.The fins on the sides of the body are used to balance the fish, for propulsion, for steering and paddling.The pectoral fins on the fish's underside are used for steering.The anal fin in the male livebearer is modified for use during internal fertilisation - it becomes a penis-like organ called a gonopodium.
