just a little bit.
mostly this is about their behaviour.

T-RhinoCrocs live and behave somewhat like how the Kindariku do, except the species as a whole isn't nearly as amorous or as war-like. They have systems for how each class and type lives and acts- though this does not always change ones behaviour.
Common Crocs are used for back-breaking labor and general outdoor work, hence Commoners tend to grow much larger and look much gruffer and more intimidating. Don't let their exterior fool you, though, Commoner Crocs have been said to be the most caring and passionate. While yes, what they do is demeaning, but they enjoy it nonetheless.
