Sharks and whales are enormous ocean creatures that have large, torpedo-shaped bodies and dorsal fins. Both species swim well in the water, use their senses to catch prey and, as meat eaters, rely on carnivorous food to survive. Both the shark and whale have large teeth and huge jaws, and neither seem to show mercy when they kill.
According to LiveScience.com, there are many similarities between whales and sharks. Whales and sharks are both endangered species that adapt to live in various temperatures and environments - cold, warm, salt or fresh waters - to survive. Both sharks and whales live quite a long time. Some experts believe sharks can live to be 50 to 100 years old. Whales often live to be 60 to 100 years old.
While the teeth are different, whales and sharks both have extraordinary sets of them that serve a significant purpose and contribute to their overall health. Sharks have an outer coating on their teeth that contains 100 percent fluoride, which explains why they never get cavities. There are certain species of whales that have baleen plates in their mouths that enable them to filter food from water, making it easier to catch and consume food.
