One example is the so called "airbreathing catfish" (Clariidae). |
This family of fish has a labyrinth organ which allows them to breathe air. Some species from this group can "walk" on land. For example the Walking catfish (Clarias batrachus) of Southeast Asia, can "walk" on land by wriggling and using its pectoral fins, this allows it to move between the slow-moving, and often stagnant and temporary bodies of water in which it lives.
Another amphibious species of this family is the Eel catfish (Channallabes apus), which lives in swamps in Africa, and known to hunt beetles on land.
Some eels, such as the European eel and the American eel, can live for an extended time out of water and can crawl on land if the soil is moist.
Also, Mudskippers (Oxudercinae).
This subfamily of gobies is probably the most land adapted of fish. Mudskippers are found in mangrove swamps in Africa and the Indo-Pacific, they frequently come onto land and can survive in air for up to three and a half days.
Mudskippers breathe through their skin and also through the lining of the mouth (the mucosa) and throat (the pharynx). This requires the mudskipper to be wet, limiting mudskippers to humid habitats.
This mode of breathing, similar to that employed by amphibians, is known as cutaneous breathing. They propel themselves over land on their sturdy forefins.
