Mayhew 1962 Dec.14 UCR, Riverside Co., Calif. I still have 2 young Crotophytus wisligeni, 2 young Sceloporus magister, 2 young Sauromalus obesus, 4 young Phrynosoma m'celli, and 1 Amphibolurus pictus in cages in the laboratory. The Phrynosoma m'celli were just returned to the lab. today after a period of 9 1/2 weeks in the vivarium (Oct. 9) where they have been without food. The lights are still off in their cage so they can continue to "hibernate". They had all nearly stopped eating before they were placed in the vivarium. The lights in the cage containing the Crotophytus wisligeni have been off since because they had stopped eating. Neither the Sceloporus magister nor the Amphibolurus pictus eat in any quantity now, even though the lights are still on in that cage for 11 hours each day. The only animals that possess any appetite are the Sauromalus obesus. The thin S. obesus wakes over when flowers are offered, and eats quite a few blossoms. However, it doesn't eat as much as during the summer. The fat one still eats lots of mealworms & some flowers.
