First up, we have the dolphin—everyone’s favorite aquatic genius. Dolphins have brains so large and wrinkled, they look like a used sponge that’s seen some stuff. They recognize themselves in mirrors, which is more than I can say for some toddlers. But here’s the kicker: dolphins also pass a test where they understand pointing. That’s right, a fishy mammal can read human body language better than your ex.
Yet, for all their smarts, dolphins still get high on pufferfish. Yes, scientists have filmed them passing around a toxic pufferfish like a joint at a Grateful Dead concert. Is that intelligence or just a really, really good Thursday night?
