  1. Breed reptiles in captivity: Crocodilians

    A study in 2012–2015 at the Smithsonian’s National Zoological Park, Washington DC, USA (Augustine 2016) found that Cuban crocodiles Crocodylus rhombifer bred in captivity, but hatching success of eggs was low. Twenty-six eggs were produced in 2012 and 24 in 2015. A total of three eggs hatched successfully and a further four produced hatchlings after eggs were opened manually or hatchlings were assisted during emergence. All eggs came from a single breeding pair of adult crocodiles, and 10 from each clutch that showed signs of development were incubated (eight in a 1:1 mixture of vermiculite and water, and two in suspended incubation containers). Eggs in suspended incubation containers were suspended over saturated vermiculite or a saturated sponge and standing water. Incubation containers were vented throughout the process and water was added to the vermiculite weekly.
