  1. Relocate nests/eggs for artificial incubation: Snakes

    A study in 1981–1992 in the Okinawa Islands, Japan (Kamura & Nishimura 1993) found that artificially incubating habu Trimeresurus flavoviridis eggs resulted in some eggs hatching successfully. A total of 265 eggs hatched successfully (total number of eggs not given). When both hatchlings and un-hatched embryos were included, the ratio of females to males was equal (217:234). In 1981–1992, eggs from 62 female snakes were collected. They were incubated at 25–30°C in individual containers containing cotton or sphagnum moss Sphagnum sp., saturated with water.
