Fish have fins which help them to swim. Different fins have different purposes like moving forward, turning and keeping upright position. the paired fins help them to move forward. The unpaired fins help them to maintain balance and the tail help them to change the direction.
pushs the fish to move
The caudal fin of most fish provides thrust to move the fish forward. An exception would be the seahorses which do not have the fin. Their tails are prehensile.
Whales are mammals which means that they have lungs. Fish do not have lungs, they have gills. Whales also have a different way of swimming than fish. They move their tail fin up and down to move forward. While fish move their tail fin left to right to move forward. Whales also communicate with each other through whale songs. Fish cannot.
by moving there fin
The caudal fin or better known as the ¨tail¨ of a fish is used for propulsion (Thrusting forward).
In most fish, the tail provides forward thrust. However, I have seen certain fish use their pectoral fins to provide sustained forward thrust.
Force created by the tail and tail fin to propel the fish forward and steer the fish;
Flippers in fish, also known as fins, are used primarily for stability and maneuvering. The pectoral fin can help fish dive, climb, turn left or right as well as back up. The pelvic fins help the fish maintain an upright position while swimming and the tail fin is responsible for forward movement and speed.
the left fin or also known as the dorsal fin
Fish move by swimming. They move their fins back and forth to swim. Some fishes have a swim bladder which is an organ that help bony fish stay in different depth.
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?
It uses there fin to move and there gills to breath in oxygen
