Some sharks swallow their prey without needing to chew. Other shark varieties, like the Port Jackson Shark, grind the prey using their broad back teeth. Some sharks are also filter feeders. When eating large prey, sharks injure them first to bring them under control and then use their teeth to bite and grind their prey.

Sharks, like fishes and cetaceans, have fins. These fins stabilize the shark and help it stay afloat in the water as well as move forward. Without their fins, sharks won’t be able to glide through water or hunt for their potential prey. Therefore, fins play a crucial role in facilitating the shark’s movement.

Cows pant during scorching summer months since they need to dissipate heat from their bodies. In addition to panting, you will notice them being restless, drooling, eating less, and standing more often. As such, it becomes necessary to cool them down, either by providing them with water or keeping them in shade.
