Microchipped - Certificated Australian Lung Fish 12-15cm Last One

Lungfish are really fascinating because they’re like a living bridge between fish and amphibians — a window into evolution. Here are the most special things about them:

🌊 Unique Features of Lungfish

1. Lungs and Gills Together
   
• Unlike most fish, lungfish can breathe with lungs (not just gills).
• They come to the surface to gulp air, especially in low-oxygen waters.
• Some species (African lungfish) are obligate air breathers → they’ll drown if they can’t reach the surface.
3. Dormancy / Estivation
   
• African lungfish can survive months to years without water.
• They burrow into mud, secrete a mucous cocoon, and slow their metabolism until rains return.
5. Extremely Old Lineage
   
• Lungfish have existed for over 400 million years (Devonian period).
• They’re considered “living fossils” because they still retain primitive traits linking fish to land vertebrates.
7. Huge Genome
   
• The Australian lungfish (Neoceratodus forsteri) has one of the largest genomes of any vertebrate (40x bigger than human DNA).
9. Long Lifespan
   
• Some can live over 100 years (especially Australian lungfish in captivity).
11. Closest Living Relatives to Tetrapods
    
• Genetically, lungfish are closer to humans, frogs, and reptiles than to other fish.
• Studying them helps us understand how animals first transitioned from water to land.

🐟 Fun Facts

• They have a very strong bite — can crush snails, clams, and even small turtles.
• Their movement on land (using fins like limbs) gives scientists clues about how the first four-legged animals evolved.
• Only 6 living species remain today: 1 in Australia, 1 in South America, and 4 in Africa.
