This week’s question:

Both whales and sharks are animals with fins to help them maneuver through the water. What is the difference between the tail fin of a shark and of a whale?

BONUS: A whale shark, which can measure up to 40 ft long, is one of the largest animals in the ocean. Is the whale shark a whale or a shark, and what characteristics make it this?
