By: Lubna Tanveer & Brittany Johnston INTRODUCTION Today I am going to talk to you about Ridge-nosed Rattlesnakes scientific name is Crotalus willardi. He is found in the southwest of United States and Mexico. At the mountain ranges above 4000 feet and below 9000 feet elevation. He eats primarily lizards, mice, and centipedes. He uses his venom injected through long, hollow, retractable fangs to kill his prey. He is reddish brown, orange-brown in color and sides of the face are marked with sharply contrasting white lines on a dark reddish brown background. When he is young he has a dark gray, black, or light yellow tail. His neck is slender and the head is broad and triangular. The best thing that he has is his tail because on the end of the tail he have rattle, it is made of loosely interlocking keratin's sections. Ridge-nosed Rattlesnake does not lay eggs in nests. He actually gives birth to live young. They mat one summer. Following summer 2 to 9 young ones are born. Fun fact about Ridge-nosed Rattlesnake is in 1986 he become official state reptile of Arizona. Many of them are without true rattles; they vibrate their tail against leaves to produce a rattling sound as a warning.  discoverer, Professor Frank C. Willard. WHERE DO I LIVE? I am found in the southwest of United States and Mexico. At the mountain ranges above 4000 feet and below 9000 feet elevation. WHAT DO I EAT?I eat primarily lizards, mice, and centipedes but it also occasionally takes birds and scorpions. I use my venom injected through long, hollow, retractable fangs to kill. HOW DO I LOOK ? I am reddish brown, orange-brown, or rust in color and my chin and sides of the face are marked with sharply contrasting white lines on a dark reddish brown background. My back is marked with pale crossbars lined with darker coloration along the front and back edges. When I am young I have a dark gray, lack, or light yellow tail. My neck is slender and the head is broad and triangular. The best thing that I have is my tail because on the end of the tail I have rattle, it is made of loosely interlocking keratin's sections. When I become adult, a new rattle section is added each time I sheds its skin. HOW DO I REPRODUCE? I do not lay eggs in nests. I actually give birth to live young. I mat one summer. Following summer 2 to 9 young ones are born.  In 1986 I become official state reptile of Arizona. Many of us are without true rattles, we vibrate our tail against leaves to produce a rattling sound as a warning. ACTIVITY Grade K-1 Create your own three feeding PowerPoint.
