When you want to get schooled on how schools of fish live, breath, and migrate, you're diving right into what zoologists specializing in the study of fish call ichthyology.
Strap on your scuba gear and dive to the bottom of the ocean and you'll be in a sweet spot for any ichthyology expert. With its origins in the Greek word ikhthus, meaning "fish" and the suffix -ology, or "the study of," ichthyology stretches as far back as the Stone Age — when studying fish meant having something to bring home for dinner.
