Thus, the correct answer is ‘Lepidosiren. ‘
Why are they called lungfish?
In lungfishes these organs are, both in function and in structure, primitive lungs like those of amphibians. The name lungfish is thus well applied: these fishes have lungs that are derived from the swim bladder (an organ used for buoyancy in most bony fishes), which is connected to the alimentary tract.
How many species of lungfish are there?
six species
Worldwide, there are six species of lungfishes. Four species in the genus Protopterus(Family Protopteridae) are found in Africa. One species Lepidosiren paradoxa (Family Lepidosirenidae) is recorded from South America. The Australian Lungfish is the only species in the Family Ceratodontidae.
Where are lungfish found?
African lungfish live in freshwater swamps, backwaters and small rivers in West and South Africa. These prehistoric animals have survived unchanged for nearly 400 million years and are sometimes referred to as “living fossils.”

What fish has lungs and gills?
The African lungfish’s dorsal (back) side is lighter, and its body and fins are dotted with black or brown spots. 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.
Do fishes have lungs?
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.
Why do lungfish have lungs?
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.
Why is Dipnoi called lungfish?
The Dipnoi are a group of sarcopterygiian fish, are are commonly known as the lungfish. Their “lung” is a modified swim bladder, which in most fish is used for buoyancy in swimming, but in the lungfish also absorbs oxygen and removes wastes.
What and why lungfish is so unique?
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.
Do people eat lungfish?
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
