Captive husbandry and breeding of Gonyosoma boulengeri

Abstract. The rhino rat snake Gonyosoma boulengeri is a medium-sized arboreal colubrid snake from southern China and northern Vietnam. Captive specimens maintained at the Zoological Society of London presented little difficulty in husbandry and were found to breed between March and June. A clutch of 9 eggs were laid on the 16 May 2008 and a clutch of 8 eggs were laid on 4 July 2013, following manipulation of the captive environment to reflect natural seasonality for this species. Post-laying incubation temperature was maintained at a constant 28.0 ˚C and lasted 52 days for the 2008
clutch and 57 days for the 2013 clutch. All individuals from the 2013 clutch had sloughed their skin for the first time by 10 days post-hatching, and five of the six fed, subsequent to sloughing, by 20 days post-hatching.
