A lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.

What is special about lungfish?
Lungfish are best known for retaining ancestral characteristics within the Osteichthyes, including the ability to breathe air, and ancestral structures within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton. Lungfish represent the closest living relatives of the tetrapods.
Can lungfish breathe air?
Unlike other fish with gills alone, lungfish can surface, take a breath and survive when other fish might be lacking air. In fact, much like many sea mammals, lungfish are obligate air breathers—they have to breathe air above water periodically to survive.
Can lungfish breathe underwater?
In their natural setting, African lungfish come up for a breath of air every three to five minutes. While underwater, they breathe through their gills.
Can lungfish drown?
They have two lungs (like ours) and can breathe air. ... And although they have gills, lungfish have true lungs, and they breathe through their mouth as well as respire through their gills. In fact, they must have access to air, or they will drown. The water's fine—but so is the mud.
How does lungfish keep its body hydrated during Aestivation?
The African lungfish, Protopterus annectens, is ammonotelic in water despite being ureogenic. When it aestivates in mucus cocoon on land, ammonia is detoxified to urea. During the maintenance phase of aestivation, urea accumulates in the body, which is subsequently excreted upon arousal.
Do lungfish have limbs?
The videos revealed that lungfish commonly use their hind, or pelvic, limbs to elevate their body off the surface and propel themselves forward. Though the forelimbs look similar to the hindlimbs, they were not involved in locomotion, the authors found.
Can a fish drown?
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen. Fishing equipment, such as some types of hooks, can damage the gills.
Can lungfish be pets?
As Pets. Housing: The African Lungfish can live in a tank with other small fishes. However, it is best to keep them under solitary conditions as they are very aggressive and can eat the small fishes. Lungfishes grow rapidly and hence it is important that they should be provided with a large tank from the beginning.
Is lungfish edible?
Human consumption of the lungfish varies by population; the Luo peoples occasionally do so but the Sukuma avoid eating lungfish due to a taste which is "locally either highly appreciated or strongly disliked." As technology advancements such as longlines and gillnets have been increasingly applied over the past 50 ...
How long can a lungfish stay underwater?
Once the water returns and the mud softens, the lungfish will wriggle out of its burrow. Some reports claim that the fish can stay underground in dried mud for as long as four years.
Can lungfish survive without water?
During drought it digs a pit and encloses itself in a capsule of slime and earth leaving a tiny opening for air. The capsule dries and hardens but when rain comes the mud dissolves and the lung fish swims away.
How long can lungfish live underwater?
African lungfish, Protopterus annectens, can live in suspended animation, called aestivation, without food and water for three to five years. They wake up when water becomes available.
Do fish ever fart?
Most fish do use air to inflate and deflate their bladder to maintain buoyancy which is expelled either through their mouth or gills which can be mistaken for a fart. ... Point being – No farts.
Do fish ever get bored?
Just like any other pet, fish can become bored, too. And while they won't chew up your shoes, keeping them occupied will ensure they live a healthier life. ... Bettas particularly enjoy moving them around the tank, but just about any fish will be curious enough to check it out.
Do lungfish have teeth?
The Ethiopian lungfish, Protopterus aethiopicus, has at the front of the upper jaw two rather rounded teeth with a hard transverse (from side to side) bridge. The lower jaw has a number of crushing teeth. The prey is sucked in, crushed, and thoroughly chewed; such a manner of eating is rare among fishes.
