Fish fins are used to generate thrust and control the subsequent motion. Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins. As they swim, they use other fins, such as dorsal and anal fins, to achieve stability and refine their maneuvering.

How do aquatic animals swim?
Aquatic animals like fish have streamlined body which help to maintain balance in water. They also have fins and tails to swim. They move their tail side to side and fins forward and backward to move forward. That's how they swim.
Do fins help fish swim?
Fish swim by flexing their bodies and tail back and forth. Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. ... Fish use their back fin, called the caudal fin, to help push them through the water. The fish's other fins help it steer.
Which animals use fins to swim?
Animals with flippers include penguins (whose flippers are also called wings), cetaceans (e.g. dolphins and whales), pinnipeds (e.g. walruses, earless and eared seals), sirenians (e.g. manatees and dugongs), and marine reptiles such as the sea turtles and the now-extinct plesiosaurs, mosasaurs, ichthyosaurs, and ...
Why do fish have fins?
Almost all fish have fins that they use for swimming (locomotion), balance, stability, and steering. A catfish has dorsal, adipose, caudal, anal, paired pelvic, and paired pectoral fins.
How do animals swim faster?
Fast species typically taper down toward the rear, culminating in a very narrow caudal peduncle. This shape minimizes drag while preserving space to hold the mighty muscles required to move so fast. The shape also allows minimizes recoil of the body as it moves, increasing efficiency.
What special features do aquatic animals have for swimming?
Answer Expert Verified. They have gills to breathe, they have special wings to swim forward, their tail. These features lead them to swim in water.
Can a fish swim without fins?
Bony fishes also have an operculum, which helps them breathe without having to use fins to swim.
Why is it easier for fish to swim in water?
Fishes can easily swim in water because they have streamlined bodies, which produces minimum friction in water and energy required to overcome this friction is very less.
What helps the fish to float and submerge into the water?
The trick is the swim bladder, which is basically like an air-inflated balloon that can expand and contract depending on how much gas is inside. When the swim bladder expands it will increase in volume and therefore displace more water. This increases the fish's buoyancy and it will float upward.
What are fins used for in swimming?
Many competitive swimmers, or those trying to improve their technique, will use fins to increase their speed through the water, helping to improve their posture and keeping their hips high in the water. Using fins in this way helps you to focus on a particular aspect of your stroke such as hand position.
What are fins used for?
Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluids. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation. Fins first evolved on fish as a means of locomotion.
Do dolphins have flippers or fins?
Instead of arms and legs, dolphins have fins. The dorsal fin helps the dolphin maintain stability. The pectoral fin is used for steering and movement. Each tail fin is called a fluke.
How do tails help fish?
The tail fin (called the caudal fin) is the main source of movement for most fish. It's like the motor on a boat. ... This helps the fish to move more efficiently through the water.
How do fins and gills help a fish?
The gills (found under the gill covers) allow the fish to breath. As water moves over the surface of the gills, oxygen is absorbed - like lungs in land creatures. ... The Fins help the fish swim. The large muscles of the body actually do most of the work, but the fins help with balance and turning.
What is the function of tail fin in fish?
The caudal fin, or tail, of a fish is the only fin to be connected to the vertebral column. It is the primary means of locomotion for most fish. Unlike many marine mammals with tails that use an up-and-down motion, fish generally use a side-to-side thrust of their caudal fin for propulsion.
