Ctenosaura similis
A small population of Ctenosaura similis was studied in Belize, British Honduras. Ctenosaurs were most abundant in areas disturbed by man. Juveniles and adults were ecologically separated in the study area. Courtship behavior was observed in the early part of the dry season. Eggs hatched in June or July and a hatchling tripled in length during its first year. C. similis is omnivorous. Most activity occurred near burrows and the greatest distance moved was 88 m. Ctenosaurs basked in heliothermic and thigmothermic positions and shifted locations as the day progressed to remain in the sun. They were often active during the hottest hours of the day. Overt aggressive behavior was not observed within the population although an outsider was attacked and the population's males generally were not seen in close proximity to one another. Territoriality was probably present within the population.
