Breed reptiles in captivity: Snakes – Vipers
A study in 1969–1980 at Houston Zoological Gardens, USA (Carl et al. 1982) found that Aruba Island rattlesnakes Crotalus unicolor bred successfully in captivity. In 1973–1980, four females produced a total of nine litters of 2–5 live young/litter, or 3–8/litter when including still born young and infertile eggs. Three of these litters (2–4 live young/litter) were produced by two females born in captivity. The oldest female also produced a single infertile egg on three occasions. In 1969–1976, two female and two male snakes were acquired. Snakes were housed in a glass fronted enclosure (80 x 90 x 140 cm) with a gravel substrate, rocks and plastic plants, or in aquaria of various sizes with a paper substrate and hide boxes. Temperatures were maintained at 28°C and humidity was 85% in the enclosure and 75% in the aquaria. Snakes were occasionally temporarily separated and then returned to the same enclosure.
