What is Lungfish?
Lungfish are special and prehistoric freshwater fish found in South America, Africa and Australia. Historically, there have been hundreds of species of these fish, although only a handful survive today and many scientists believe that Lungfish represents a bridge from completely water to amphibious species. This fish is considered an endangered species because it has lost a large amount of habitat. In Australia, nature conservation programs began to improve their status, but in other parts of the world it is not so good.
Lungfish resembles an excessive eel, with some specimens weighing up to £ 25 (11 kilograms) at maturity and reaching a length of 6 feet (1.8 meters). Larger fish commonly occur in Australia. Fish have spotted green colors, with fins resembling residual legs and long dorsal fin. They are insatiable predatory fish and consume small fish that can be captured, as well as some plant material. Some of them have been to live for more than 80 years at age, with several such seniors held in captivity.
lungfish get their special name from the lungs or bladder they have. In addition to filtering oxygen from water, air is also able to breathe and some species will actually drown if they are held under water. This adaptation allows the fish to survive in low oxygen -level environments and means that they can often be found in areas with very minimal water. They must emerge to breathe oxygen and often occur in shallow lakes and streams.
These fish enjoy muddy stream beds and will plunge into them to lay eggs and nests. In addition, it is known that some species have come to peace during dry spells by digging deep into mud areas and building a cocoon with an air hole that adds fish until the water level is increased again. In this way, they may pause for three years, it seemed that it was growing out of the ground when the rain returned.
Some aquarists I will maintaineats Lungfish as pets. Because they are predators, Lungfish are usually held alone or with other resistant species that can protect themselves. In addition, because they like to face, high volume filter system is required to make the water clean. They certainly create a unique complement to fish collections, with their surprisingly expressive faces and archaic appearance.
