"Ah! Yeah! Anglerfish!" Jungkook nods emphatically, looking at Yoongi as though he's a genius, then around the aquarium as though he might be able to spot an anglerfish somewhere if he watches closely enough. (Though, now that he thinks about it, he's pretty sure that he's never seen an actual anglerfish in his life, and he's been to plenty of aquariums. Wasn't there something about their habitat that can't be replicated in an aquarium? He's not sure.)

He giggles when Yoongi leans forward and sharply bites the air, then lets himself be pulled along down the hall, gait occasionally slowing whenever he spots something that catches his interest. Which is fairly often. Unlike the zoo, where all of the exhibits have some amount of distance between them, the side by side nature of the tanks makes it very easy for Jungkook to be distracted the whole way down the hall.

"Some of them don't have teeth though, right? Like, like uh, the whales and their baleens? Although I guess whales aren't technically fish... or like, what're the called, parrot fish? The ones that look like they've got beaks. Maybe they've got teeth inside of those beaks, though," Jungkook mumbles half to himself.
