Okay, so it's pretty clear that he's not really a dragon - he's just a really big lizard. The Komodo dragon is named for Indonesia's Komodo Island, but its forked tongue was thought to resemble that of mythical dragons.
The tiny African mammal resembles a shrew, sporting an elephant's signature snout. But the elephant shrew is neither an elephant nor a shrew: it's a sengi.
Striking resemblance, but can you imagine trying to get a saddle on that thing? Seahorses are actually just awesome-looking fish, but poor swimmers (and awful runners).
Technically, they're not bugs and only half of them are even ladies. At least Americans have one-up on the Brits, though, who named them after birds. During the Middle Ages, insects were eating crops and spoiling harvests, so farmers prayed for relief. When the ladybugs began showing up to eat the insects, farmers called them the "Bug of Our Lady" or "Our Lady's Bug" in reference to the Virgin Mary. Hence, ladybugs.
Though not actually hogs - just spiny foraging mammals- they do grunt like pigs when hunting for food, which is what inspired the moniker.
