Turns out the most intelligent animal on earth is the Tridacna gigas, or giant clam. You probably can’t tell from the outside, but they're always thinking. Through the power of MRIs, we’ve discovered their remarkable faculty for language, reasoning, empathy, math, drawing, art, music, sports betting, video gaming, even joke-telling. In fact, they're capable of profound discourse and political debate, but are still working on evolving the appropriate mouthparts. Same with writing—they have so much to say, so many gripping stories to tell. But as you may know, they've got no hands. Once they do, though, you'd better watch out.
