The shark species with teeth that are best adapted for resisting forces caused by side-to-side slicing or sawing during feeding is the sawfish. Sawfish have long, flattened rostrums (snouts) with teeth along the edges, forming a saw-like structure called a rostrum. These teeth are specialized for slashing through schools of fish and dismembering prey. The sawfish's teeth, with their saw-like arrangement, are well-suited for lateral cutting forces during feeding.
