NAP TIME: Footage posted to the Denver Zoo's Facebook page shows Groucho, a 49-year-old elephant, circling around his pool before taking a nap. He reportedly uses his trunk as a snorkel while he sleeps. | Fox News

Happy New Year! Today we are wishing the happiest 51st birthday to the dominant male of Toyota Elephant Passage: Groucho. This old man has been taking the not-so-little 🐘🐘🐘🐘 under his wing and teaching them the ins and outs of being polite, respectable, and powerful male elephants, in the same way that male elephants learn from one another in Southeast Asia. The expected lifespan for the species is 47 years, so we're grateful for every extra moment we get with old man Groucho. | Denver Zoo C
