Its reproductive biology is poorly understood. Males are 39-42 mm SVL and 3-31/2 years of age when they reach sexual maturity; females mature a year later, and are >44 mm SVL. At the onset of markedly increased precipitation in the fall, courtship is inferred from the presence of sperm masses in female cloacae. The number of eggs in a clutch ranges from 2-12 (x = 7.33) and is not significantly correlated with the size of the female. Large females may exhibit biennial ovarian cycles; however, many females above the minimum size for sexual maturity are non-reproductive and either become reproductive after reaching age 4 or have ovarian cycles >2 years.Read More
