CC updates! :D

Hey guys, it's me again, updating this precious cc family blog(: There has been quite a buzz going on in CC recently, so here are some updates!

1) some of the 09 Docents from various stations have decided to seek permission from the zoo management to include sharks and tigers conservation into CC station for the whole of the CNY period (till Feb end). To know more about tigers conservation and facts, you can visit HERE for more information.. We're still collating information and waiting for the management's response!
For those who are very passionate and have the time to join us in this conservation projects (not restricted to CC docents only), please join us! Click HERE to leave us a message on the wall OR simply speak to us on our tagboard (scroll down, at the right hand column) :D

2) please join "Wildlife Reserves Singapore" on Facebook! It's quite an efficient platform to learn about more about the animals you love! Click HERE to join! If you love animals and your docents job, here's the best place to get the updates of things which most visitors will not know (from behind the scenes!!!) :D

3) PP station has some newborn primate babies and some of them are endangered species in the WORLD! Pictures follow..Lion-tail macaque (above) - the most endangered macaque in the world. Don't they look like lions with their mane-stuff around the faces?


Black and white Columbus monkey



The baby is pure white in colour! As they grow older, they will turn into black and white, just like their mum and dad in the pictures!!


Family


Black Howler Monkey (female). The female is yellow to light brown in colour for their hair. As for male, theirs is black in colour. See the picture below for the baby!


Baby black howler monkey is also light brown in colour! Wonders which colour it will turn into when it grows up!

Colugo's classification

Quoted from Norman Lim's Colugo book:

Flying Lemurs are classified in the order Dermoptera, from the Greek words derma, meaning "skin", and ptera, meaning "wing", thus "skin-wing". This is one of the smallest of all the 26 mammalian orders. There is only one family in Dermoptera, that is Cynocephalidae, from the Greek words cyno meaning" dog", and cephalus meaning "head", hence "dog-head".

Lately, results from morphological studies and molecular studies have often yielded differing views on the relationship of flying lemurs with other extant mammals. Of great interest to geneticists is the recent discovery that the genomic composition of the mitochondria in dermopterans is highly similar to that of simian primates (suborder Anthropoidea; which includes humans), making them our likely distant relatives. Professor Ulfur Amason of Lund University, Sweden went on record declaring that: "We (human beings) are more closely related to flying lemurs than we are to half-apes."

When the Colugo was excluded from the primate order, one reason was that it has a small-brain, large ventricle syndrome, something that it shares with other non-primates like the Koala of Australia (Phascolarctoscinereus) and the Three-toed Sloth of the Neotropics (Bradypustridactylus). This, however, could be due to other factors that these animals share, i.e. mainly an exclusive diet of leaves that exposes them to high levels of ph yo toxins. In other words, the toxins in the Colugo's diet might cause developmental disturbances that give it a small brain and conceal its true relationship to primates. So, while the original classification by Linnaeus was later rejected, he might in fact have been right all along in placing the Colugo among the primates!

So........ in summary, Colugo is a mammal in the order Dermoptera!
