So we continue on within the Vietnam module, wanted to go ahead and really kind of bring to focus the biodiversity of primates within Vietnam. So here we have another cladogram, and we'll go ahead and we'll define out the animals that exist in the area. So we've got our strepsirrhines, so we've got some loris species. Got our cercopithecoidea, so those are our old world monkeys, a number of species there. And then hominoidea, so we have both six different species of gibbons, and then of course we have humans there. So this example of some pretty good humans. All right, to refresh, home to approximately 25 primate species, and I'm saying 17 of which are endangered or critically endangered. So remember, from the last video, from the intro, we said that there are 20 threatened with extinction. So a little bit of difference, not all of the ones that are threatened with extinction are currently endangered or critically endangered. But that does not mean that, with this rapidly rising human population and restriction of areas and the other threats that we'll discuss, that these species are not threatened with extinction. Okay, so to kind of do a laundry list of all the species, we'll go ahead and we'll start with our strepsirrhines. So our nycticebus, these are going to be our lorises. We have both the pygmy slow loris and the slow loris, so both are vulnerable. For old world monkeys within Vietnam, We have actually six different macaque species. So you have rhesus macaques, a least concern species. We have our stump-tailed macaques, which are going to be vulnerable. Assamese macaques, on the upper right-hand corner, and these ones are near threatened. Our long-tailed macaques, so we've got two different species of long tails. One is kind of the crab-eating or the general long tailed macaque. And then the second one is the Con Song long-tailed macaque, so a species that lives in a very restricted habitat on Cordell Island. And then the last one are pig-tailed macaques, which are also a vulnerable species. Okay, if we move into our langurs, so in the upper left-hand corner, we've got our Cat Ba langur or the golden-headed langur. So a species that we've seen before, and that we'll talk about a little bit more in the next few videos, and that's a critically endangered species. That's one of the ones on the top 25 most endangered primates. We've got our Delacour's langur, so again, another critically endangered species. Two species of silvered langurs, so Germain's langur, and then the Annamese langur. Upper right-hand corner, we've got our Hatinh langurs, we got our Francois' langurs, and our gray langurs. What's really kind of fun about all these guys is when you start to look at the facial features on a number of them, some of them have different tufts. Some of them have these fantastic crests that stand up top their head, like Delacour's langur on the left there has those white pants. So the Vietnamese name for them is [FOREIGN], which is little monkeys in white pants, which is kind of a fun way to look at them. But again, a really wide, wide diversity of old world monkeys. And then we've got our odd nose group. So our Tonkin snub-nosed monkey, only living in Vietnam, critically endangered species. We'll talk more about them, and we've mentioned them in the past. The red-shank douc, so a species that lives in Vietnam, Cambodia, and Laos. We'll talk a little bit more about them specifically in Son Tra Nature Reserve. And then we've got our grey-shanked doucs, so a species that is again endemic to Vietnam, only lives in Vietnam. And then our black-shanked doucs. So 11 species found in Vietnam, really, really an impressive diversity of animals. And then as I mentioned, we've got six species of gibbons. So I have three of them pictured here and then another three named. But the ones pictured on the right-hand side, we've got our western black-crested gibbons, we've got our southern yellow-cheeked gibbons, and our northern white-cheeked gibbons. Now, for a number of years, there was a lot of taxonomic debate in terms of how many gibbon species there actually were. And when they went through and they did more research on it, they found that there was also the eastern black-crested gibbon, a critically endangered one, the northern yellow-cheeked crested gibbon, and the southern white-cheeked crested gibbon. So lots of exciting work being done to figure out what's going on with the taxonomy of gibbons. And again, that just shows the incredible diversity of primates that are currently found in Vietnam. So with all the diversity in mind, we'll go ahead, and in the next video, we're going to talk about some of the threats. So be thinking about some of the threats that we've already discussed and how you think those are directly applicable, or what you think would be different within Vietnam.
