Earlier this week, I invited you to test your knowledge about this fascinating endangered species. Today on Whale Shark Day, celebrate these creatures by taking our 1-question quiz below.

Seahorses aren’t horses, and mole-rats are neither moles nor rats. Not every animal is what it seems. So, how do whale sharks fit into this puzzle?

Is a whale shark a whale or a shark?

Whale sharks serve as a powerful symbol of the diverse marine life we must protect—and since they are endangered, it’s even more critical that we do so.

Thank you so much for your support. With you by our side, we'll continue to protect these creatures and the oceans they call home.

Yours in conservation,
