Amphibious fish


Amphibious fish are fish that are able to leave water for extended periods of time. About 11 distantly related genera of fish are considered amphibious. This suggests that many fish genera independently evolved amphibious traits. These fish use a range of terrestrial locomotory modes, such as lateral undulation, tripod-like walking (using paired fins and tail), and jumping. Many of these locomotory modes incorporate multiple combinations of pectoral, pelvic and tail fin movement.

Some kinds of amphibious fish based on how they breathe:

Lung breathers:

  • Various “lunged” fish: These are now extinct. A few of this group were ancestors of the basal tetrapods that led to all tetrapods: amphibians, reptiles, birds, and mammals.
  • Lungfish (Dipnoi): Six species, have limb like fins, and can breathe air. Some are obligate air breathers. Some species will bury in the mud when the body of water they live in dries up, surviving up to two years until water returns.

Gill or skin breathers:

  • Rockskippers: These blennies are found in Panama and elsewhere on the western coastline of the Americas. These fish come onto land to catch prey and escape aquatic predators. They often come out of water for up to 20 minutes.
  • Wooly sculpin: Found in tide pools along the Pacific coast, these sculpins will leave water if the oxygen levels get low and can breathe air for 24 hours.
  • 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.
  • Eels: 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.

So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
