Why are butterflyfish called butterflyfish?

What is the function of the vasculature in butterflyfish?

How do butterflyfish survive on the reef?

Relying on their striking markings, rapid movements, and agility, butterflyfish are well equipped to evade the many hungry predators on the reef. The fish’s compressed disc shape allows them to maneuver along the reef easily and quickly and to hide in small areas between corals.

What is excretory system in fish?

Excretory and reproductive systems of a fish The gills are also part of the excretory system. Blood carries waste products and excess salts to the gill filaments. Carbon dioxide (CO2) and ammonia are excreted by the gills. Fish living in seawater and brackish water also excrete excess salt from their gills.

What is the function of mucus in fish?

In the epidermis of most fishes are cells that produce mucus, a slippery material like runny gelatin, that helps the fish slide through the water. The mucus wears off daily, carrying away microscopic organisms and other irritants that might harm the fish.

What is excreted from blood in fish?

Blood carries waste products and excess salts to the gill filaments. Carbon dioxide (CO2) and ammonia are excreted by the gills. Fish living in seawater and brackish water also excrete excess salt from their gills. The liver also removes wastes from the blood. The liver cleans blood after it has picked up digested products from the intestine.

What is a butterfly koi fish called?

Butterfly koi, longfin koi, or dragon carp are a type of ornamental fish notable for their elongated finnage. The fish are a breed of the common carp, Cyprinus carpio, which includes many wild carp races as well as domesticated koi (“Nishikigoi”). …

Are there different types of koi fish?

For example, there may be two koi of a particular type, but if one has better coloration or sizing than the other, it will typically sell for more. There are also koi called “butterfly koi”, and these are koi that were bred with long-finned carp to produce a fish with flowing fins.

How do butterflyfish eat coral?

The Ornate Butterflyfish feed by scraping the coral, dislodging polyps with each pass of their mouth. These fish have been documented eating large amounts of coral mucus as well and yet they seem to do no noteworthy harm to wild reefs.

What are the systems of a fish?

A complex organism like a fish has digestive, nervous, sensory, reproductive, and many other systems. Fish consist of interacting groups of organ systems that together enable a fish to function. The integumentary system is commonly called the skin.

What is the function of the organs in 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.

What type of blood do fish have?

The blood of fishes is similar to that of any other vertebrate. It consists of plasma and cellular (blood cells) components. The cellular components are red blood cells (RBC), white blood cells (WBC) and thrombocytes designated as formed elements.

How does blood leave the renal region in a fish?

All blood leaves the renal region through post-cardinal veins, but renal portal circulation is absent in lamprey and hagfish (Cyclostomata). Vertebrates excrete nitrogenous wastes from the body through the intestines and skin. However, most metabolic wastes are excreted through specialized excretory organs.

How is ammonia excreted from the body in fish?

Ammonia is the end product of protein catabolism and is stored in the body of fish in high concentrations relative to basal excretion rates. Ammonia, if allowed to accumulate, is toxic and is converted to less toxic compounds or excreted. Ammonia is eliminated from the blood upon passage through the gills. How do birds excrete?

What do fish excrete from their bodies?

Most of what is excreted by fish is undigested material and dead bacteria. Fish usually convert nitrogenous wastes into ammonia, which is secreted into the water through the gills. 80% to 90% of a fish’s nitrogenous waste is dealt with in this way. The rest will be formed into urea and pass out through the rectum.

Where does excretion take place in fish?

In fishes some excretion also takes place in the digestive tract, skin, and especially the gills (where ammonia is given off). Compared with land vertebrates, fishes have a special problem in maintaining their internal environment at a constant concentration of water and dissolved substances, such as salts.

Why is the excretory system important in fish?

Excretory System in Fishes • In vertebrates, the excretory and reproductive organs are morphologically interrelated because certain excretory ducts are used for the discharging of gametes also. So it has been convenient to treat them together as urinogenital system.

Why is the excretory and reproductive system in fish called urinogenital?

Because the excretory and reproductive organs of the fish are very close together, so these two systems are collectively called the urinogenital system. However, excretion and reproductive system work separately.

How is glucose excreted from the body in fish?

Most of the glucose is removed by the same process. In freshwater fish, the kidneys play an important excretory role in removing secondary nitrogenous compounds such as creatine and uric acid from the body, but the gills are the main organ through which major nitrogenous wastes such as ammonia (NH 3) and urea are removed from the body.

What is the function of mucus in discus?

Movement of water and ions in a freshwater fish; once again, the arrows into and out of the skin are short due to the presence of scales and mucus In addition to its other functions, mucus reduces drag when a fish swims. It covers the scales, filling in any gaps or irregularities and reducing friction. Discus fish are a type of cichlid.

What is hagfish mucus and why is it important?

Mucus is a very important substance for fish. It protects them in multiple ways and also has some surprising functions beyond protection. Although the thought may sound disgusting, fish mucus could be useful for humans. It may be possible to use the protein fibres in hagfish slime to make new fabrics and materials.

Why does a fish need mucus?

Mucus is helpful for a fish because in conjunction with the scales it partially blocks the movement of water into and out of the fish’s body. This helps to maintain constant conditions inside the fish. Other parts of the body also influence the salt and water concentration in the fish. The urine contains more or less water and salt, as necessary.
