The Smithsonian's National Zoo is warming up to a new monitor lizard this winter. The young Komodo dragon, named Onyx, moved into his new habitat at Reptile Discovery Center Dec. 10, 2020. The team is just getting to know Onyx, but animal keeper Matt Neff has already nicknamed him “Junior” because he resembles the Zoo’s 22-year-old Komodo dragon, Murphy, in both looks and temperament. Onyx is a little over a year old, and keepers estimate he weighs just 2-3 pounds. He is tiny compared to Murphy who usually tips the scales at 146-152 pounds. That’s about average for Komodo dragons. They are the world’s largest lizards and can reach lengths of about 10 feet.
