  1. Breed reptiles in captivity: Snakes – Vipers

    A study in 1972–1976 at Fort Worth Zoological Park, and a second private collection, USA (Tryon & Radcliffe 1977) reported that lower California rattlesnakes Crotalus enyo enyo bred successfully in captivity. In 1974–1976, three females produced four litters of 2–7 young each following gestation periods of 176–299 days. One litter of seven included two young that were stillborn and one that died soon after birth. The overall sex ratio was 12 males to two females and one of unknown sex. In 1972–1974, one female and one male snake were acquired by Fort Worth Zoo, and two females and a male were acquired by a second private collection. Snakes were housed in a 60 cm fibreglass exhibit with a gravel substrate, or a 38 litre tank with a newspaper substrate. Temperatures ranged from 22–33°C.
