Imagine this: You’re in the middle of the Gulf of Mexico with a big fish on the line. But suddenly, you’re surrounded by whale sharks, the biggest fish in the world. What do you do?! If you’re a scientist, you get curious. Marine biologist Rafael de la Parra tells us how and why he got a headcount of the biggest whale shark party ever seen. We adopted a whale shark!
