The main shapes are rounded, square, forked and lunate. Here are four main caudal fin (fish tail) shapes: Rounded tail: Sometimes this is called a paddle tail. Eels have rounded tails.

What causes fin and tail rot in Betta fish?

1. Fin and Tail Rot. As the name suggests, this disease affects the fins and tails of betta fish. It can be caused by bacteria or fungi. The fins and tail appear to melt away as a result of rotting. It can be prevented by keeping the aquarium or living conditions of the fish clean.

Why do fish have triangular tail fins?

Some fish have shortened tail fins roughly the shape of a triangle without separate lobes. Fish that inhabit the bottom of the body of water and camouflage themselves tend to have triangular caudal fins. Though not as fast as other fish, the design allows for a quick burst of speed to escape predators and hide.

What are the lobes of a fish tail fin called?

Ordinarily, caudal fins have an upper and lower lobe. In bony fish, the lobes are generally the same size and shape. This is called a homocercal tail fin. A homocercal tail ends at and connects to the fish’s spine.

Do betta fish have big tails?

The front two fins are called pectoral fins and are sort of like the arms. A fish’s tail fin is called the caudal fin, and is like a fish’s hips and legs.

What are the parts of the body of a fish?

Why do fish have fins on their back?

Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling.

Why do fish have vertical tails?

Show activity on this post. While fish tend to move from side to side (lateral undulation) for which a vertical tail makes sense, the land ancestors of marine mammals had their limbs under them and so their spines were already adapted to up and down movement (dorsoventral undulation).

What is the base of the tail fin called?

The base of the caudal fin (tail) where the vertebral column ends, which can be seen as a crease in the skin when the tail is flexed from side to side. The tail fin. The portion of the body between the posterior end of the anal fin base and the caudal base. The portion of the head between the eye and the posterior edge of the preopercle.

What is the difference between upper and lower lobe of tail fin?

Upper lobe of tail fin is much longer than lower lobe with vertebral column (backbone) flexing upward and extending into the upper lobe of the fin, common in some sharks. Upper and lower lobes of tail fin are approximately symmetrical and the vertebral column ends at or near the middle of the tail fin base, not extending onto the fin.

What is a lobe finned fish called?

Lobe-finned fishes are a class of bony fishes called Sarcopterygii. They have fleshy, lobed, paired fins, which are joined to the body by a single bone. The fins of lobe-finned fish differ from those of all other fish in that each is borne on a fleshy, lobelike, scaly stalk extending from the body.

Do betta fish need a bigger tank?

This is why bettas purchased in cups often become brighter-colored and their fins grow larger when placed in the right-sized aquarium – they are much healthier in a larger aquarium. I would note that smaller, independent fish stores generally store their bettas in more appropriately sized tanks.

Can bettas get sick from fin rot?

But most healthy animals do not get sick, even when there are pathogens in the water. If your betta develops fin rot, there’s probably something else wrong with your tank that made your fish susceptible to infection. Obviously, other animals in the tank experience the same conditions and could also get sick.

What happens when a fish has an infection in its tail?

The entire fin and/or tail has rotted away, and the infection begins to attack the body, potentially leading to loss of life. You may also notice your fish seems listless or doesn’t feel like eating anymore, since its body is working hard to fight the infection.

Why does my Betta have a chewed up tail?

A chewed-up, tattered-looking tail and/or fins is mostly likely caused by fin rot or by a tank mate’s nibbling teeth. If your betta starts looking a little worse for wear, you should determine and treat the cause as soon as possible. Fin rot is a sign that your fish has a bacterial disease.

What are the fins on the bottom of a fish?

Anal fins are on the ventral (bottom) surface of the fish, behind the anus. Fish use these for stability while swimming. Pectoral fins are located on each side of the fish, around where the head meets the body. These are often thought of as the fish’s “arms”. Pelvic fins are located on each side of the fish, near it’s bottom middle.

What is a fish’s tail called?

This is what we refer to as the fish’s tail. Anal fins are on the ventral (bottom) surface of the fish, behind the anus. Fish use these for stability while swimming. Pectoral fins are located on each side of the fish, around where the head meets the body. These are often thought of as the fish’s “arms”.

What is the function of the tail fin in a fish?

In bony fish, the lobes are generally the same size and shape. This is called a homocercal tail fin. A homocercal tail ends at and connects to the fish’s spine. The swinging from side to side of the caudal fin allows the fish to propel itself through the water by what is termed carangiform locomotion.

What are the parts of a fish?

EXAMPLES Fins • Hard parts: scales, teeth, • skeleton, otoliths Connections: inside-and-out • Internal structures and organs • Sensors • Many external and internal features of fishes are equivalent to our ownalthough several notable exceptions exist, such as the gas bladder (same as swim bladder) and gills.

What parts of a fish are equivalent to our own?

Parts of a Fish. Many external and internal features of fishes are equivalent to our own although several notable exceptions exist, such as the gas bladder (same as swim bladder) and gills. Major anatomical differences address significantly different challenges between living in water vs. air.

What are the internal organs of fish?

The brain, stomach, liver, and kidneys are same as in man for the fish and perform the same function. Some organs are different; man has lungs to breathe whereas fish has gills for the same purpose. The name and function of the internal organs are listed below with their functions. The fish body is built on this main structural framework.
