In the later Devonian, descendants of pelagic lobe-finned fish — like Eusthenopteron — were followed by:
Panderichthys, suited to muddy shallows;
Tiktaalik with limb-like fins that could take it onto land;
Early tetrapods in weed-filled swamps, such as: Acanthostega, which had feet with eight digits, and Ichthyostega with limbs. Descendants also included pelagic lobe-finned fish such as coelacanth species.
