Eggs of C. exsanguis, perplexus, tesselatus, and velox were harvested from field-caught lizards and incubated. All the hatchlings are females. Supplementary evidence from exclusively female hatchlings of these forms and C. cozumelus, collected in areas where no other teiid lizards occur, supports the hypothesis that these species are parthenogenetic.
