Meeting the African Penguins!

I also was just able to upload another one of the many videos that I took when me, my dad, my grandma and grandpa, and my friend Masaki Kleinkopf went to the Cheyenne Mountain Zoo a month or so ago and got to meet the African penguins there!  This video takes place before we actually enter the enclosure, while we are still looking in on the penguins at the entrance to the exhibit!  Enjoy, and be sure to check out some of the other videos on there while you are at it!

At Last: Success With Primos!

Today's birthday post goes out to Megan Pullen!  Happy birthday Megan!  If you have a birthday coming up, just email me the date at cuyvaldar123946@gmail.com with the date and your favorite animal, and I will do my best to get a post in!

So the lock that I had ordered for my Primos Truth Cam finally arrived over the weekend, and on Sunday night I was finally able to set up the camera!  I made sure to use some of the fox urine in and around the area in the hopes of attracting red foxes.....and we got ourselves a hit!

For those of you wondering how in the heck I got fox urine, not to mention why, here is the skinny.  I started this thing called Foxbook.  Here is the description about what exactly it is, lifted from my "Foxbook" tab.  "Recently, my friend Masaki Kleinkopf and I started an experiment of sorts, to see whether foxes were in the area.  My mother had purchased fox urine to spray in her garden to keep garden pests such as squirrels from eating her vegetables.  I borrowed some and sprayed a bit on a wall near by to my use.  Underneath the spray site, I buried a plastic bin, and poured water into the dirt in the bin.  This turned the dirt into mud, and the plastic bin prevented the water from draining.  So now the bin remains muddy for days at a time, making it more likely for the fox visitors to leave footprints.  On the very first day, we got a hit, and three of the four days now we have gotten hits!  In perhaps my best pun yet, I created the term "Foxbook."  You see, it is like a social messaging site, where visitors can leave "Posts" on other peoples "Walls."  Haha."

So there is that.  We also got a skunky visitor, as well, along with a little child who tried to steal the camera from the tree.  Thank goodness for the lock!  Anyways, here are the pictures!  Enjoy them!

We have actually talked about foxes a great many times on this blog in the past.  Here are the posts in which we have done so:

• Channel Island Fox:  Shrinky Dink: The Channel Island Fox and the Island Effect
• Red Fox:  Guards of the Fairy Penguin
• Fennec Fox:  What Is It?  The Weekly Challenge #5 Answer
• Gray Fox:  The Fauna of South Carolina: Cetaceans, Foxes and Otters
• Red Fox:  The Fox's Animal Magnetism

Proterosuchus....or Should I Say "Broterosuchus?"

Before we learn about Proterosuchus, it will be helpful to discuss where this creature comes from.  Proterosuchus is an archosaur, and to understand what an archosaur is, we must first travel back 320 million years into Earth's history: back....to the middle of the Carboniferous Period.  To travel back to that period of Earth's history, click HERE TO SEE A POST I JUST MADE ABOUT THE EVOLUTION OF THE ANIMALS THAT WE ARE TALKING ABOUT RIGHT NOW.  Unless, of course, you are fine with just accepting the idea that the archosaurs are relatives of the dinosaurs, pterosaurs, and crocodilians, in which case you can just skip that post.  I think it's interesting, though, so it might be worth checking out!

Well, that was confusing.  So how does all of this evolutionary rig-a-ma-roll pertain to Proterosuchus?  Well, in his excellent book entitled "Gorgon," paleontologist Peter D. Ward actually talks about that.  Here is that passage from his book:

"During the Triassic a whole new suite of vertebrates populated the land.  The oldest true "ruling reptiles," the stock that would ultimately give rise to the dinosaurs, are found in the oldest rocks of the Triassic.  The most ancient of these is Proterosuchus.  Yet within several million years, there was a variety of these predinosaurs, belonging to a group known as the archosaurs.  From these ancestral stocks the successful lines of crocodiles and crocodile-like animals known as phytosaurs evolved.  From other members of this group came lizards, snakes, and, by the middle of the Triassic, the first true dinosaurs."  

Well, that certainly sums it up quite nicely, don't you think!  Anyways, Proterosuchus was around the size of the extant Komodo dragon, and was one of the largest reptiles alive during its time, in the Early Triassic Period.  Similar in appearance to the modern day crocodiles, it has been theorized that this animal would lie in wait much like the crocodilians, ambushing its prey when it came down to bodies of water to drink.  One bit of evidence that causes some scientists to believe that Proterosuchus hunted like the crocodilians was that the eyes of Proterosuchus were were located on top of its head, again like the crocodilians.

Remains of Proterosuchus are known from both China and South Africa, where it was first discovered by Robert Broom, a famous South African paleontologist, in 1903.  This specimen was discovered in the Karoo Basin, an enormous desert in South Africa where large numbers of fossils have been discovered.

The Archosaurs: A Brief Summary of Reptilian Evolution

320 million years ago, during the Carboniferous Period, the flora and fauna looked quite different than it does today.  Oxygen levels in the atmosphere were much higher, allowing insects to grow to enormous sizes.  Centipedes were the size of snowboards; dragonflies were the size of hawks; and spiders were the size of dinner plates.  There were also no mammals.  Not only that, but there were no reptiles, no dinosaurs, and no birds (which, of course, are dinosaurs).  There were, however, amphibians.  Amphibians, like frogs and salamanders, cannot lay their eggs on dry land, and instead must lay them in pools of water.  This is because the eggs that they lay, unlike those laid by dinosaurs, birds, reptiles, and monotremes (the two egg-laying mammals), have soft-shelled eggs, which allows water to move in and out of them.  They would simply dry up on land!

Around 320 MYA, however, something changed.  Some of these amphibians developed what is known as an "amniotic egg," the type of egg typified by the dinosaurs, birds, reptiles and monotremes.

Around 5 million years after that, around 315 MYA, another major split occurred, this time between the amniotes.  This split resulted in two lineages, the first of which, the synapsids, would one day become the mammals.  The second of these two lineages was the sauropsids.   Within the sauropsids was the group known as the archosaurs.  The archosaurs, in turn, suffered two major splits.  The first split was the crocodiles, alligators and their kin.  They joined with the rest of the reptiles contained within the sauropsids.  The second large split within the archosaurs was another large group, off of which the pterosaurs broke off, before the rest of the group became dinosaurs (and, in turn, birds).  If you look at the family tree below, you can see that the group known collectively as the "reptiles" is what is referred to as a "paraphyletic group."  Put simply, that means that a paraphyletic group consists of "all the descendants of the last common ancestor of the group's members minus a small number of monophyletic groups of descendants, typically just one or two such groups." So for reptiles, that means that the group consists of the last common ancestor of all reptiles (which includes both extant reptiles and the extinct mammal-like reptiles, the precursors of the mammals), including all of the descendants of that ancestor....EXCEPT for the mammals and the birds, which are defined separately.  I feel like I have confused you enough, so I am not even going to get into the whole dinosaur debate.

Viagra, Pornography, and the Giant Panda

Today's birthday post goes out to Maggie Zhang!  Happy birthday Maggie!  If you have a birthday coming up, just email me the date at cuyvaldar123946@gmail.com with the date and your favorite animal, and I will do my best to get a post in!

One of the many pictures of the giant panda that we took at the San Diego Zoo in California.  In fact, all of the giant panda pictures in this post were taken by my family and I.

Today we will be looking at a very interesting animal known colloquially as the "giant panda" (Ailuropoda melanoleuca), which translates to "black and white cat-foot."  Classified as "Endangered" by the IUCN, the giant panda is not only a symbol of its homeland of China (as well as its only land), but also for conservation efforts worldwide, being the symbol for the World Wildlife Fund.  It's closest living relative is the South American spectacled bear, and is frequently referred to as a "living fossil" due to its early branching from the rest of the family Ursidae.  Due to its basal position in the bear family, controversy surrounded the panda for many years as scientists struggled to determine where it belonged, often suggesting a close relation to both the raccoon and the red panda, who gets its name from the giant panda.  These two are only distantly related, however, despite the fact that they live in the same area, have largely the same diet, and both have what is essentially a thumb on their front paws.

Notice how the panda is grasping the bamboo, employing the use of its thumb appendages

It is estimated that the giant panda has been evolving away from the other bears for more than three million years due to the discovery of Ailuropoda microta, or the "dwarf giant panda."  The first skull discovered of the dwarf giant panda was in rocks in southern China that are around two million years old.  The skull indicates that this relative of the giant panda would have grown to around three feet in length, while the modern panda grows to a length of around five feet.  Despite the size difference, the skulls of the dwarf and giant pandas are actually quite similar anatomically, and dentition studies (studies of the animals teeth) indicate that the diet of Ailuropoda microta consisted largely of bamboo, much like the extant panda, for whom bamboo composes about 99% of its diet.  The giant panda will also consume tubers, grasses, and even meat when it can get it, like carrion, but also rodents and birds.

And now the reason why most of you are here: panda pornography and Viagra.  When I was researching the giant panda for this post, I ducked on to Wikipedia to employ the use of their range map of the giant panda.  At the bottom of the page, under the "See Also" tab, I couldn't help but notice the page entitled "Panda Pornography."  More than a little intrigued, I investigated, and its really quite funny, and not as weird as many of you were probably expecting.

No panda pornography here, but more of "The giant panda at the zoo searching for the food that the zookeepers left for it around the exhibit"

Many attempts to breed the giant panda in captivity have been made, given its "Endangered" status.  They are doing better now, and many pandas have been bred in zoos in China as well as at the San Diego Zoo in California, where apparently six have now been born.  (To see the "Panda Cam" at the zoo, click HEREEEEE).  Zoologists at a Chiang Mai Zoo in Thailand showed their pandas "panda pornogrpahy," literally just a bunch of videos of other giant pandas mating.  They hoped that the pandas would use this as a guide, and that it would arouse them.  Huh.  Despite the fact that this particular group of zoologists seemed to think the whole thing a success, efforts to duplicate the experiment have failed, causing the whole concept of panda pornography to come under intense scrutiny.

Furthermore, some Chinese scientists at the Wolong Nature Reserve attempted to excite the pandas by giving them Viagra.  Again, huh.  I mean, wouldn't you think that Viagra would be geared towards humans, and not necessarily bears?  I would, but I guess I don't know.  Despite their efforts, the Viagra trials were unsuccessful.

Acrobatic Felines: The Serval

This birthday post goes out to Maiji Castro, happy birthday Maiji!  If you have a birthday coming up, just email me the date at cuyvaldar123946@gmail.com with the date and your favorite animal, and I will do my best to get a post in!

Today, the serval is going to be added to our pantheon of acrobatic felines!  The serval (Leptailurus serval) is another one of those mid-sized cats, like the caracal, bobcat, and lynx, and is actually closely related to the caracal!  DNA studies place the serval in what is frequently referred to as the "Caracal Lineage," with the serval being the basal-most, or the earliest to split off, of these three cats.  The other two are, of course, the caracal, and its closest relative, the African golden cat.

So that tells us about the serval's phylogenetic position in the feline family tree, but what else do we know about this interesting creature?  And how is it so acrobatic?  Well, the serval, much like the caracal, is a jumper, perhaps not quite as high of a leaper, but nevertheless an amazingly nimble cat.  It's incredible jumps are assisted by its long legs: in fact, the serval has, in relation to its body size, the longest legs of any feline.  To see the incredible leaps of the serval, click on the link below!

A Pretty Awesome Serval Jump!

The serval is labeled "Least Concern" by the IUCN, and has a very wide distribution across the continent of Africa, excluding deserts (like the Sahara) and the equatorial jungles of the Democratic Republic of the Congo and the neighboring countries.  The serval once inhabited the countries of Tunisia, Algeria, and Morocco, as well, but seems to have been extirpated (caused to go extinct in one country as opposed to extinct overall; a local extinction).  It is also now found in Tunisia again, but was reintroduced there by humans.

Four albino servals have been documented throughout the years, all of which were born in captivity.  One was born in Canada in the early '90s, but died just a week or two after birth.  The other three were all born at Florida's excellent cat sanctuary, Big Cat Rescue.  (If you want to see a ton of really, really cute pictures, click on this link HEREEEEEEEEEEEEEE to their Facebook page.  Trust me, you will NOT be disappointed!)  One of these three died a few years back, but they still have two!  First is Pharaoh, who is featured in the picture below, and Tonga, who is featured in all of the rest of the pictures, and who recently overcame nose cancer.  Enjoy!

23-Fact Tuesdays: The Natural Bridge Wildlife Ranch!

Remember 23-Fact Tuesdays?  Not very surprising if you don't, since there was only one and it took place a few weeks ago.  But we are going to do one again (despite the fact that today is Sunday) and this time, all of the facts are going to be drawn from the Natural Bridge Wildlife Ranch (NBWR for short!)Adventure Guide Book!  If you recall, the Wildlife Ranch was the place that I talked about in our Animal Spotlight featuring the Aurochs a few weeks ago, where you drive through this large area and the animals will come up to your car!  Pretty neat, huh!?  And most of the pictures that I upload for this blog post will actually be ones that we took down there!  So, as Mrs. Frizzle from the Magic School Bus says, "Seat belts, everyone!"  Let's do this thing.

1.  The African bongo, a type of antelope, has a prehensile tongue that it uses to grab vegetation, much like a giraffe.

2. The "Critically Endangered" addax from the Sahara Desert has flat and broad hooves, which help to keep the animal from sinking into the sand.

A picture of an addax that I took while in Palm Desert, California, at the excellent zoo called "The Living Desert"

3.  The addax also is very lightly colored, which helps to reflect heat away from the animal, keeping it cool.

4.  The South American rhea can run up to 40 m.p.h.

A picture of the rhea that my mother took at the Natural Bridge Wildlife Ranch on our visit in 2008.  The rhea is one of the ratites, like the ostrich and the emu, amongst others.

5.  The Patagonian cavy is the second-largest rodent in the world, second only to the capybara.

6.  The Watusi is the largest horned animal in the world, and its horns can be six feet across when fully grown.

A picture of a Watusi, with a calf, that my mother took when we visited the Natural Bridge Wildlife Ranch in 2008

7.  The African springbok pronks, meaning that it jumps with all four feet off the ground.  Typically, when an animal pronks, it is either during pursuit by a predator, or simply during play.  During pronking, the springbok can jump ten feet in the air.

8.  The scimitar-horned oryx is labeled "Extinct in the Wild" by the IUCN, hunted to extinction in the wild for their horns, which the animal would sometimes use to spear predators to death.

 

 

9.  The gemsbok was kept in large, semi-domesticated numbers in ancient Egypt, where they were killed for sacrificial purposes.

10.  The Indian barasingha "has the unique ability to submerge their heads in water while closing their nasal passages," which "allows them to take advantage of vegetation in the swampy areas of their homeland."

11.  The name "wildebeest" came from the Dutch settlers who settles in South Africa.  It means (can you guess?) "wild beast."

12.  The nilgai, or the bluebull, is the largest of the Asian antelope.

13.  The "Near Threatened" white rhinoceros is the largest of all of the rhinoceros species, and the second largest land mammal, second only to the African elephant.

14.  The white rhino will wallow in mud to cool off, as well as to help protect their skin.

15.   The name "rhinoceros" comes from the Greek words "rhino" (which means nose) and "ceros" (which means horn).  Think about the name Triceratops real fast: tri=three, tops=face, so then cera (like "ceros") = horn!

16.  The "Critically Endangered" bactrian camel, the larger of the two camel species, can go several days without no water, spit when agitated, and can survive extreme temperature swings, from -20 degrees F, all of the way to 100 degrees F!

A picture of the bactrian camel that I took at the Denver Zoo when I went there with my friends Masaki Kleinkopf and Brynn Conroy in April of 2012

17.  The ostrich is not only the largest of all of the birds, but it is also the only bird to have two toes.

This picture of ostriches stalking our car looks like something out of Jurassic Park

An ostrich accosting my sister for food at the Natural Bridge Wildlife Ranch in 2011

18.  The blackbuck, native to India and Pakistan, is a "Near Threatened" species.  According to the guidebook, there are more blackbuck in Texas than there are in India and Pakistan.

19.  The gait of the giraffe is unique amongst quadrupeds.  As they walk, they swing both of their feet on one side of their body at the same time.

A picture of one of the giraffes from the Cheyenne Mountain Zoo from my visit a few weeks ago

20.  Giraffes eat around 75 lbs. of food a day, and can drink around 10 gallons of water in one standing!

21.  The heart of the giraffe can pump up to 20 gallons of blood per minute.

22.  There are two sub-species of sika (type of deer).  The Formosan sika, which inhabits Siberia, and the Japanese sika, native to Japan and Korea.

A picture of a Japanese sika that I took in 2011 at the Natural Bridge Wildlife Ranch

 23.  The North American elk is frequently referred to as the "Wapiti."  Wapiti is actually the Native American term that refers to the white patch of hair on the rear of the animal.
