How does respiration occur in fish?

Respiration in fish takes place with the help of gills. Most fish possess gills on either side of their head. Gills are tissues made up of feathery structures called gill filaments providing a large surface area for exchange of gases. Fish take in oxygen-rich water via their mouths and pump it over their gills.

Do fishes breathe air?

The answer is yes, some fish can breathe air. In fact, a few species can even survive on land, proving that it is not always bad to be a fish out of water.

How do fish respire through skin?

Many developing fishes breathe exclusively through their skin prior to gill development. Larval Monopterus respire through extensive subepithelial capillary networks. Posthatch Neoceratodus have a ciliated respiratory epithelium covering their body surface.

How do fish exhale?

Like us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. Gills are branching organs located on the side of fish heads that have many, many small blood vessels called capillaries.

What type of respiration occurs in fishes?

Cutaneous respiration (gas exchange occurs across the skin of an organism instead of gills or lungs). E.g., Reedfish and mudskippers. An electric eel can respire through buccal cavities. Some fishes like Scolopacidae respire through digestive tracts….Respiration in Fish.

Why do fish need to breathe?

Organisms like fish, which live in water, need oxygen to breathe so that their cells can maintain their living state. To perform their respiratory function, fish have specialized organs that help them inhale oxygen dissolved in water. Respiration in fish takes with the help of gills.

How does a Lungfish breathe?

Some fish can breathe air through vascularized (i.e. having veins to transport oxygen and other nutrients) bladders, but the lungfish have actual lungs. This allows them to take oxygen from the air, rather than just the water due to the insufficiency of their lungs. Most have two lungs, although the Australian lungfish only has one.
