This week, my family and I visited the Melbourne Aquarium.  I saw the Australian lungfish there and really wanted to learn more about them.  Also known as the Queensland lungfish, they are a really cool fish.

Here are five interesting facts about them:

  1.  They are a very large freshwater fish, growing to 1.5 metres in length.
  2. Unlike the unrelated African and South American species of lungfish, the Australian lungfish only has one lung.  It can stay out of the water for several days at a time, helping it to survive drought and move from one pond to another.
  3. They can live for a long time, with one Australian lungfish surviving for 80 years in captivity.
  4. They are mostly carnivorous, eating frogs, tadpoles, small fish, invertebrates and some plants.
  5. They are a very old species, with fossils dating back over 100 million years.  In fact, scientists knew about the fossils before living lungfish were discovered by modern scientists.

I hope that you found these facts interesting and learned something new.

Are there any other interesting facts that you would like to share about Australian lungfish?
