I've learned so much about animals since venturing on this A-Z quest. The xantusia is also known as the dessert night lizard found in desert regions of Mexico. However, contrary to its name, it is active during the day. The xantus, a kind of hummingbird, is also found in Mexico. Didn't think there would be an "X" animal didja? (let alone 2 from the same region) Yay!
