The crocodile-people comprise of a large, spell-bound family. Though human in their mind, they are very herptilian on the outside
Their head is roughly human, as are their arms. However, their hands are scaly like a lizard and have reptilian digits with claws. Their neck is also human. Their chest has many resemblances: The front of the breast is half-way between human and crocodile, the shoulders are lizardly just beside the breast, and the back is snake-like. Below the chest is another portion of the thoracic trunk, which is entirely snake-like. This part is flexible, and is as long as the chest proper. The entire belly, from the chest to the gonads, is covered in smooth crocodilian scales. Their abdomen is fully crocodilian. They have a crocodilian tail around the length of the legs, which are frog-like in their structure. These legs are crocodile-scaled, but with webbing and lizardly scales/claws on the toes. Their body and parts therein are roughly human in their proportions
Based on their anatomy, how would these beings most realistically move?
