Do lungfish have gills or lungs?

Of extant lungfish, only the Australian lungfish can breathe through its gills without needing air from its lungs. In other species, the gills are too atrophied to allow for adequate gas exchange. When a lungfish is obtaining oxygen from its gills, its circulatory system is configured similarly to the common fish.

Can you have both lungs and gills?

Which fish does not breathe through gills?

mudskipper
Breathing without gills Fish from multiple groups can live out of the water for extended time periods. Amphibious fish such as the mudskipper can live and move about on land for up to several days, or live in stagnant or otherwise oxygen depleted water. Many such fish can breathe air via a variety of mechanisms.

Why do fish have gills instead of lungs?

Instead, fish breathe underwater thanks to their gills. These gills serve more or less the same purpose as our lungs, however, only instead of extracting oxygen out of the air, fish gills extract oxygen out of the water the fish swim in. Breathing is one of those few essential actions required for most life.

What do you need to know about lungfish fish?

The Australian lungfish reportedly breathes air through the nasal openings, the mouth remaining closed. In contrast to the more advanced bony fishes,…
