The silvery lutung (Trachypithecus cristatus), also known as the silvered leaf monkey or the silvery langur, is an Old World monkey. It is arboreal, living in coastal, mangrove, and riverine forests in Peninsular Malaysia, Sumatra, and Borneo.
I just watched a great BBC Documentary called “Monkeys Revealed“. It covered fascinating facts about a numerous range of monkeys or primates. My favorite was the Silvery Lutung or Silvered leaf monkeys of Malaysia. The babies are born ginger in colour whereas the adults are a beautiful silvery colour. The babies are really cute and the documentary proposed that their coloration is to make them “hi-vis” or to give them high visibility vests, so to speak! It certainly showed the babies were very noticeable in the trees for the adults to look out for and protect!
The baby lutungs, also called langurs are born with orange fur and turn to silver at approximately three months of age, although some can begin their transformation aged just one month, according to Beth McDonald, a senior keeper at the San Diego Zoo
The link below tells more about these delightful monkeys, and shows an un-missable photo of a baby turning silver, head first.
Considering the extensive habitat loss that has taken place within the range of the species, there is reason to believe that this species is in decline, probably at a rate of less than 30% over three generations (approximately 30 years), thus qualifying if for listing as Near Threatened, almost qualifying as threatened under criterion A2c.
A monkey is a Primate and Primates are mammals belonging to the order Primates. Homo sapiens or human beings are Primates. If you are interested, you can find out how human beings sprung from the Order of Primates, and that apes and monkeys also originated from the same ancestor, by reading the Post below.
I also liked the Japanese or Snow macaques whom cuddled up in sub-zero temperatures, to keep warm during winter. They even took turns to get into the middle “hot spot”, as shown by cameras that filmed thermal ( hot ) areas. Mind you, I wasn’t so happy to see them having a hot bath in the hot springs, but turfing out the lowly ranked. I discovered that the monkeys have “ranks” e.g. the females are ranked according to their mothers, and the males according to their physical prowess and strength.
I liked the colorful Mandrill Baboons, but was not keen on the Hamadryas Baboon male “leader” whom attacked the females just to throw around his weight.
In finishing, I recommend this Documentary if you get a chance to watch it.
I love Orang-utans and of course, Gorillas ! Please see the information below about conservation of the magnificent Orang-utans.
