The videos revealed that lungfish commonly use their hind, or pelvic, limbs to elevate their body off the surface and propel themselves forward. Though the forelimbs look similar to the hindlimbs, they were not involved in locomotion, the authors found.

Do lungfish have fins or limbs?

New research on the fin development of the Australian lungfis elucidates how fins evolved into limbs with hands with digits. The main finding is that in lungfish a primitive hand is already present, but that functional fingers and toes only evolved in land animals due to changes in embryonic development.

Can lungfish walk?

Lungfish are thought to be related to the first creatures that crawled out of the water to colonize land. But because the lungfish has scrawny, whiplike fins, scientists thought that the ability to walk must have evolved later in terrestrial quadrupeds.
