What it does
Whether this species of Craspedocephalus lays eggs or bears live young is as yet unknown. They are ovovivipar. The female ley they transparent eggs in a bulk and she curl up around the eggs to incubate and protect them. Between 12 and 30 hours, all babies hatched and stay close to the mother. I breed them in 2026. It took approximately seven months from mating to egg-laying.
