(Phys.org) —The eel-like body and scrawny "limbs" of the African lungfish would appear to make it an unlikely innovator for locomotion. But its improbable walking behavior, newly described by University of Chicago scientists, ...

For most vertebrates, losing a limb is permanent, but a lucky few species—such as salamanders and tadpoles—have the ability to completely regrow complex body parts. Understanding the molecular mechanisms underlying this ...

Lungfish (also known as salamanderfish) are freshwater fish belonging to the Subclass Dipnoi. Lungfish are best known for retaining characteristics primitive within the Osteichthyes, including the ability to breathe air, and structures primitive within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton. Today, they live only in Africa, South America and Australia. While vicariance would suggest this represents an ancient distribution limited to the Mesozoic supercontinent Gondwana, the fossil record suggests that advanced lungfish had a widespread freshwater distribution and that the current distribution of modern lungfish species reflects extinction of many lineages following the breakup of Pangaea, Gondwana and Laurasia.
