What are the differences between carnivorous and herbivorous fish?

There are also differences in the gill rakers, the pharynx, the stomach (if there is one) and in the length of the intestines. In carnivorous fish, there is a definite stomach, or foregut. Herbivorous fish have no stomach but they basicly rely on a much elongated midgut area.

In carnivorous fish, there is a definite stomach, or foregut. Herbivorous fish have no stomach but they basicly rely on a much elongated midgut area.

What are the adaptations of fish?

Fish are aquatic, ectothermic vertebrates. Many structures in fish are adaptations for their aquatic lifestyle. For example, fish have a stream-lined body that reduces water resistance while swimming. Fish have gills for “breathing” oxygen in water and fins for propelling and steering their body through water.

How do fish move?

This is a relatively slow type of locomotion and a good deal of energy is needed to propel (move) the fish. Fish with streamlined bodies and a stiff, crescent-shaped caudal fin or tail, tend to move rapidly through the water by swishing their tail from side to side.

Why does a fish’s fin move side to side?

As the fin moves side to side, pressure builds up on the thrusting side of the fin and decreases on the trailing side. The gradient causes water to move sideways across the body. This lateral motion can disrupt the boundary layer, the layer of water right next to the moving body (the fish), which is crucial to reducing drag.

What is sub-carangiform locomotion in fish?

Sub-carangiform The sub-carangiform group has a more marked increase in wave amplitude along the body with the vast majority of the work being done by the rear half of the fish. In general, the fish body is stiffer, making for higher speed but reduced maneuverability. Trout use sub-carangiform locomotion.

What are the types of locomotion in fishes?

There are three types of locomotions in fishes depending on the shape of body. Eels (Anguilla) and cyclostomes having serpentine body swim by lateral undulation of the entire body that is caused by metachronal rhythm in the contraction of myotomes.

While there is great diversity in fish locomotion, swimming behavior can be classified into two distinct “modes” based on the body structures involved in thrust production, Median-Paired Fin (MPF) and Body-Caudal Fin (BCF).

What is the movement of fish?

More specialised fish include movement by pectoral fins with a mainly stiff body, opposed sculling with dorsal and anal fins, as in the sunfish; and movement by propagating a wave along the long fins with a motionless body in fish with electric organs such as the knifefish.

Can tilapia swim fast?

But they can’t swim as fast as fish using their bodies and caudal fins. As an example of how a fish moves through the water, consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance to movement and enabling the tilapia to cut easily through water.

What is the function of tail in fish?

Tail is that essential part which helps fishes to swim. They, generally, expand/stretch their muscles on either side of their body and relax the muscles on other side. This kind of motion makes them move forth in water.
