|

Most information comes from captive animals, as there is no accurate data on reproduction, including breeding season, for wild populations. Sexual maturity occurs at about 4-5 years of age. From studies of captive animals, the estrous cycle averages 35-5 days with estrus itself lasting 24-48 hours. No obvious seasonality in reproduction. Mating occurs on land and in water, typically 1-4 times during an estrous period. Gestation approximately six months, resulting in a single young (rarely twins) weighing about

CITES Appendix II. Classified as Endangered on The [UCN Red List. Primary threats are widespread habitat loss to logging and clearing for agriculture. Opportunistic bushmeat hunting has been reported in more fragmented areas and is believed to pose an additional threat to species viability. A population estimate in the early 1990s stated that there were less than 3000 individuals remaining. Although the true population size is unknown, even that estimate may be high and populations most likely are continuing to decline such that a 20% decrease over the course of the next 20 years is not without reason.
