The schematic drawing has devonian sarcopterygia lobe-fins and tetrapods four legged animals. Fishapod half fish and half four legged animals.

The list below includes six devonian lobe-fins and tetrapods as well as one from Carboniferous and one from Permian periods.

First animal in the list is the still living Coelacanth and last animal pictured is a seal as an example of a developed mammal who can swim and also move on land using its fins and breathing with lungs.

Among the mammals we know from our own world there are animals that move in water with fin like limbs. The details are different but the idea is the same as in Late Devonian lobe-fins and tetrapods. Those fins are clumsy on land ... but work somehow!
