Definition
A "plectognath" is an individual fish belonging to the former order Plectognathi. These fish are characterized by their fused or highly modified jaw structures. Think of them as the oddballs of the fish world, with specialized mouths! π They are known for their unique feeding habits, often involving crushing or grinding their food. Now largely replaced by other classifications, this refers to a fish with distinctive jaw morphology. It's a historical term more than a modern one.
