Red-Tailed Fingerphibian

Fingerphibians are a relatively new group descendant from the Finger-Fish A group of derived Sea Robins. 

Unlike their ancestors, there are exclusively freshwater species in slow-moving bodies of water. 

Like their fellow terrestrial Acanthopterygii the Blish they’ve lost many of their more fishy traits. They’ve lost their dorsal and tail fins only keeping a tadpole-like tail fin. 

Although unlike Blish they only have two limbs as Blish modified their back fins into hind limbs even though this has severely impacted the shape of the pelvis and reproductive organs (male Icthtyopterans have snake-like Hemipenes) 

They are poikilothermic unlike Blish and compared to the also poikilothermic Lunge Fish they are far less active as detritivores feeding on a variety of worms and insect larvae in the soil of the lakes and rivers with small sharp teeth to catch and eat prey. 

The hand-like fins serve to anchor them to the floor as well the three finger-like protrusions (also modified fin rays) serve as highly sensitive rods filled with thousands of electricity-sensing pits to find prey in the soil. 

Like the Finger Fish, they are capable of moving themselves on land pushing along in a mudskipper-like bounding motion a primitive lung derived from stomach tissue lets them stay on land permanently provided they stay moist and avoid predators.
