Zoo Babies: Lion Cubs at the Denver Zoo

On Saturday, my family and I went to the Denver Zoo.  We saw many awesome animals, but probably my favorite animals that we saw were the three new baby lion cubs!  Born in June of 2012, the cubs were sent to the zoo from Qatar, and will likely be shipped somewhere else once any long-term plans have been established regarding where they will stay.  For now, though, we get to enjoy the pleasure of these cubs, and now you can too!  Enjoy the pictures!

Hello there!

King of Pride Rock

The cubs look up as a HUGE flock of geese flies by overhead!  Nice timing, mother!  (That sounds like I'm being sarcastic but I actually am not.)

Ready to pounce!

Right before the goose flyover!

Your Dog May Be Dumb, But It's Brain Has More Folds Than a Cat's

When it comes to the anatomy of the brain, the more folds it has, the better.  This is because the folds create more surface area on the brain, which in turn creates more area for neurons to be, which in turn allows for more storing of information.  A month or two ago in my Psychology class, we briefly touched upon the brains of other animals.  I particularly remember the brains of the domestic dog and the domestic cat.  Even though it often seems, especially in my house, that my cat is a whole lot smarter than my dog, a quick look at the brains of both pets indicates otherwise.  The cats brain is pretty smooth in comparison to the brain of the dog.  If you think about the major differences between these two carnivores, one obvious difference sticks out like a football player in a group of people going to see the Hobbit premiere this weekend who are fully decked out in Lord of the Rings gear and are all Hobbit-sized: dogs are social creatures, while cats have a much more limited social capacity.  This probably helps to explain why your cat will suddenly and randomly bite you after you have been so lovingly petting her in your lap while she is purring.  They just don't know how to handle that much attention!  They also don't have any built-in social protocol.  Think about a socially awkward child: the situation is similar, except for the child it is simply that they had a different upbringing and not usually a matter of brain size.  Or maybe cats are just insane.

Anyways, as you can see by comparing the brains of the cat (above) and the dog (below), the dog has many more folds in its brain.  This makes sense, because the social interaction component would need more brain area to successfully function.

REAL FAST:  BELOW IS A HUMAN BRAIN FOR COMPARISON.

So with this in mind, it would make sense that the brain of the lion would be larger than, say, the brain of the leopard, now, wouldn't it?  Since the lion is a social animal, you would definitely think that.  This doesn't seem to be the case, however.  I did a little digging and couldn't really come up with much, but if I had to hazard a guess I would say its because the lion has the pride to fall back upon, so they don't necessarily need to be smart ALL of the time.  Also, leopards are extremely acrobatic, and spend a lot of time in the trees.  I suspect that this might also affect things, but I guess I don't know!  When I attempted to research it, literally all I could find was a bunch of Internet people comparing operating systems (?) called "Lion" and "Snow Leopard." 

Next we are going to compare the brains of the wolf and the red fox.  As you can see below, here our "Social Interaction=Big Brain" hypothesis is sound.  Not only does the wolf have a lot more folds in its brain, you can also see that the canyons created by the folds themselves are much, much deeper, which creates more surface area. 

Finally, let us compare the brains of the polar bear and the black bear.  HOLY.  COW.  As you can quite clearly see in the pictures below, the polar bear has MUCH more surface area on its brain than the black bear.  Now if you think about it, the environment that the polar bear is forced to survive in is much harsher than that of the black bear.  IN OUR POST ABOUT THE POLAR BEAR, we featured a video IN WHICH THE POLAR BEARS ARE PLAYING WITH SPY CAMERAS.  As the narrator points out, the curiosity of the polar bears is their "best hope for the future."  In their ever-changing world of ice and snow, which is now unfortunately melting, this curiosity is often what helps them survive the long, lean summers after the melting of the pack-ice, as well as the long, dark and cold winters.  Hopefully this brain power will be enough to sustain their populations in the future!

The Sounds of Star Wars

The dog that was once owned by George Lucas has gone down in history in more ways than one.  One very famous example stems from the dogs name: Indiana.  This inspired the first name of the swashbuckling adventure hero "Indiana Jones" from the film franchise of the same name.  Another very important legacy of Indiana (the dog) stems more from appearance.  Apparently, the idea for Chewbacca, the lovable Wookiee from the Star Wars franchise, came to Lucas when he saw Indiana sitting up in the passenger seat of Lucas's own car!  In fact, the name "Chewbacca" apparently is derived from the Russian and Ukrainian word "собака," which means dog.

Ben Burtt, the sound editor for all six Star Wars movies, recorded a number of bear sounds for the purpose of creating Chewbacca's speech.  Along with bears, cats such as the lion and the mountain lion were also recorded.  Camels were used in addition to these fiercer companions.  These were by no means the only contributions by the animal world to the sounds of Star Wars, however!  For example, when it came to the patrons in the Mos Eisley Cantina in Episode IV: A New Hope, many different tactics were utilized.  Synthesized Latin and chopped-up Swahili served for two of the customers, but animals were used as well.  One patron's laughter stemmed from a hippopotamus, while anothers came from a spring peeper tree frog.

That's not all when it comes to the Cantina scene, however!  Ponda Baba was the Aqualish alien, below, who, along with his friend Dr. Evazan, picked a fight with Luke Skywalker and Ben Kenobi.  He was "voiced" by a walrus.  Meanwhile, besides "dogs growling and bats squeaking," the "laughter" of hyenas was also used for the laughter of some of the Cantina's other patrons. 


Here are some more sounds, and what kind of animals contributed to their creation:

Geonosians:  Here is what Matthew Wood, the actor who brought the voice of the famous and much-loved General Grievous to life, has to say regarding the sounds made by the Geonosians:

"I recorded the mating calls of penguins as they came back from the Antarctic to little Phillip Island in Melbourne.  Other sounds came from when I was up in the rain forest; I was in a flying fox area, and they let me get close to these two flying foxes.  One of them had a banana, but the other one wanted some of it, so they started fighting.  They were really mad, and I recorded that whole thing.  So, for the Geonosians, Ben [Burtt] combined mating penguins and fruit bats fighting over a banana."

The penguins that he is referring to are the korora, commonly called the little blue penguins, discussed in a recent post.  They would also not have been returning "from the Antarctic," as these birds, the smallest known penguin, past or present, are not cold-weather birds, and really stick pretty close to Australia.

Boga:  One of my absolute favorite characters (yes, I know, technically she is just an animal, but still) was voiced by a combination of one of my favorite REAL animals, the Tasmanian devil, along with a few yelps from dogs and coyotes.

Wampa scream: An elephant bellow, overlied by the squawk of a sea lion.

Mynocks:  The whinny of a horse played backwards at half the normal speed, beginning with the bark of a seal.

Ugnaughts:  The noises made by these pig-like aliens were primarily from the pups of an arctic fox, as well as the mother, but a bit of "raccoons in a bathtub" was mixed in.

Rancor Noises:  The dachshund owned by the neighbors of Ben Burtt, the Syllas, barking, growling, and hissing.

The Sando Aqua Monster:  The deep growls that this massive creature from Episode I: The Phantom Menace makes were actually from the throat of Burtt's then-three month old daughter, named Emma.  "At one point, she had a growl in her voice when she was crying.  I thought, I can use this!  So I recorded that and then lowered the pitch way down in the computer."

 Kaadu:  The snorts of the kaadu were recorded from the sounds a whale made out of its blowhole when surfacing at San Diego's Marine World.

Kaadu/Gamorrean Guard:  Both of these creatures (the grunts of the kaadu, and everything for the Gamorrean Guard) were recorded from pigs.  Unsurprising, at least for the Gamorrean, given his appearance!

Poggle the Lesser - The leader of the geonosians (that is, until Queen Karina the Great is revealed in season two of the Clone Wars) was voiced in a number of different ways, but partially through "Swahili-type vocal clicks."

Acklay:  This creatures noises and shrieks were created from reworked dolphin noises, as well as a few pig sounds.

Octuparra Droids:  The sounds from these massive droids from the Clone Wars were partially created by cows.

Gor:  Pet of the aforementioned General Grievous, Gor was voiced by a mixture of a lion and a vulture.

Gundark:  This creature, first mentioned in the original trilogy ("You look strong enough to pull the ears off a gundark," said Han Solo to Luke Skywalker after his traumatic ordeal at the hands [haha irony (because the wampa gets his hands cut off)] of the wampa) was created from a conglomerate of a horse and a shrieking parrot.

I have to say, I think one of the coolest places to visit would be Skywalker Sound, the place where all of the sound and stuff for the Star Wars movies and tons of other movies are made, organized, edited, and such.  If they gave tours, then I would totally make the trip out there!  To take a tour of Skywalker Ranch would be absolutely fantastic!

Perfume-Loving Lions and Record-Breaking Cheetahs

Two interesting pieces of feline-news for you today!  The first actually takes place at the Denver Zoo!

13 year old male lion named Krueger seems to really like "Obsession," by Calvin Klein!  Apparently, if the perfume (or is it cologne?  Man-fume?) is sprayed inside of his enclosure, he goes to the same spot and "rubs his cheek on it."  When you actually think about it, it totally makes sense.  Perfumes and colognes are supposed to attract people due to pheromones inside of them.  Animals also use pheromones, mostly to communicate.

Has a cat ever done this to you?  Scent glands in the cheeks of cats (as well as in their paws) contain pheromones, used in communication.  Each cat has a unique scent, and it rubs off when they rub into things like this.  So when your cat greets you, it is partly due to affection, and also partly due to the fact that they are really marking you as their territory.  At least they aren't peeing on you!  So this explains why Krueger would rub his cheeks against the spots of Obsession sprayed around his enclosure.

Interestingly, the lions seem to enjoy Obsession more than other perfumes, and not all of the lions were attracted to it: only half of them were, in fact!  Emily Insalaco, an employee at the Denver Zoo, thinks that the lions like this particular cologne more than others due to the presence of cinnamon, which the lions have seemed partial to in the past.  If you want to see a video containing more information, click below.

Next up is Sarah the cheetah, one speedy demon from the Cincinnati Zoo in Cincinnati, Ohio!  Multiple times has this amazing cat beaten the world record for the 100 meter dash, and once even twice in the same day!  The first link below is from Sarah's first world record break, where she broke the world record twice in one day in 2009.  The second clip below is from more recently, when Sarah yet again beat the record, in June of 2012.

Simba, Pumbaa, and Other Swahili Names From "The Lion King"

Recently I decided to learn a bit of Swahili, and I have stumbled across a few things that I thought were quite interesting!  For instance, did you know that "Safari" meant "Trip" in Swahili?  I certainly didn't!  And the old movie entitled "Hatari!" actually means "Danger!" in Swahili!  Who knew! 

As I continued to learn more, I came across something else interesting.  As I was learning the animal names, I found that "Duma" meant "Cheetah," which excited me, as one of the main cheetah stars from BBC's "Big Cat Diary," one of the later seasons, is named Duma.  Next, I found out that "Chui" meant "Leopard...." and guess what?  There was a leopard named Chui, too!

Then, I found that "Simba" meant "Lion."  There was, of course, a lion that went by the name of Simba, in the first season of Big Cat Diary, I believe.  I had just assumed he was named after Simba from "The Lion King," which is still a possibility, but it could really go either way.


But I think it clear where the name of "Simba" came from for the Lion King.  As a matter of fact, many of the characters have names that mean something else in other languages.  For example, Ed, the hyena, is actually short for "Edward" in English.  Below is a list of others.

1. Nala - Gift
2. Pumbaa - Simpleton
3. Rafiki - Friend
4. Sarabi - Mirage
5. Shenzi - Uncouth
6. Sarafina - Bright Star
7. Banzai - Skulk, or Lurk

Animal Spotlight: The Sloth

Today's "Animal Spotlight" is the arboreal South American three-toed sloth (Bradypus variegatus).  The three-toed sloth holds the record for the world's slowest mammal: in fact, it is so slow, that algae grows on its fur, giving it a greenish color.  The algae helps to camouflage the slow animal in the treetops of its rainforest home.  In the case that its camouflage fails it, then it will resort to taking a stab at its attacker with its incredibly large claws.  Definitely not something that you want to take a hit from.

After perusing a few sources, I have come up with a list of the top 10 sleepiest animals, as you can see below.  The numbers are all number of hours spent sleeping a day. 

1. Koala:            20-22
2. Sloth:             20
3. Armadillo:       19
4. Opossum:       19
5. Lemurs:          16
6. Owl Monkey:  17
7. Lion:              14-16
8. Hamster:        14
9. Squirrel:         13-14
10. House Cat:     11-12 

 HERE is a link to an earlier post about the koala, and why it is so sleepy.  The sloth apparently is so incredibly sleepy simply due to the fact that its leaves are so poor in nutrients, much like the predicament the koala finds itself in.

Two other sloth facts struck me as pretty interesting.  The first one is the fact that, due to a few extra neck vertebrae, the sloth can turn its head 270 degrees, as you can see in the picture below.

The second interesting fact is that, despite the poor ability of the sloth to walk on the ground due to weak hind legs, they are actually surprisingly adept swimmers, as you can see in both of the videos below.

According to the website of National Geographic, the three-toed sloth is labeled as "Endangered" by the IUCN.  Sloths live in Central and South America, and the three-toed sloth specifically inhabits the countries of Venezuela, Guyana, Suriname, French Guyana, and Brazil.

Finally, to learn a little bit more about the sloth, click on the link below.  The video is a short clip narrated by David Attenborough, and is also quite amusing.  Enjoy!

Saying "Boo!" To A Sloth

The Komodo Dragon: Deadly Drooler or Poisonous Predator?

The Komodo dragon (labeled "Vulnerable" by the IUCN) has long had the title of "World's Deadliest Drooler."  Native only to the Komodo Islands in Indonesia, The story went that the Komodo would bite its prey and let it slowly die, eaten away from the inside out by all of the deadly bacteria that fermented in its mouth.  It ends up that this story, as that is all it is, a story, originated from just one or two accounts of the creature almost a century or so ago, and that they were based almost entirely upon observation.  After these accounts were made public, more and more researchers and scientists tagged on to this idea until, eventually, it was a scientifically accepted fact.

Further support for this hypothesis was observations of Komodos biting buffalo, a main food source, and simply hanging around for days, weeks, and (I believe) on at least one occasion, a month.  Scientists believed that the animals would slowly succumb to the copious amounts of bacteria that were at home in the mouth of the worlds largest extant lizard. 

While it is true that the mouth of the Komodo dragon was, in fact, home to a number of very virulent strains of bacteria, it seems that there are other players at work.  A group of scientists noticed that the Komodo dragon, and other closely related monitor lizards, all had interesting bulges in the sides of their mouths.  These bulges they thought resembled those seen in the Gila monster, one of just two lizards that were previously known to have venom, the other being Mexico's beaded lizard.  Komodo skulls are hard to get a hold of, however, and it wasn't until 2009 that the team of researchers were finally able to get ahold of a Komodo dragon skull to put through an MRI machine.  The MRI scan showed that the Komodo did indeed have venom glands.  Although the venom appeared not to be deadly, it was potent enough to act as a sedative.  This, the team concluded, was how the Komodo would kill its victims: sedate them with its mildly potent venom, and then finish them off when they were slow and torporous. 

This didn't explain why it sometimes took weeks for Komodos to finish off a buffalo.  Kurt Schwenk believes it is because the Komodos often don't want to risk life and limb.  So what they do is they bite their victims, and let a combination of shock and bloodloss do the trick.  As the prey slowly starves, being surrounded by Komodo dragons and unable to retreat anywhere, more and more Komodos congregate in preparation of the coming feast.  And given their slow metabolic rates, they can afford to wait, too: unlike a lion or a cheetah, they are in no hurry to finish off their prey, and see no reason to take unnecessary risks to finish off the prey.

While all of this research is highly disputed, and subject to many different points of interpretation, it does seem like the idea of the Komodo killing by its toxic drool is indeed false, although only future research will decide all of this for certain.

Acrobatic Felines: The Caracal

(Almost) everybody loves cats!  Not only the domestic kitties, but wild cats too, like the speedy cheetah, the social lion, and the elusive snow leopard, among others.  But most people don't know that there are all sorts of different cats, and thirty-six generally accepted species of cats!  Many have numerous sub-species as well, the leopard having eight or nine all by itself.

Today, I am going to introduce you to one of my absolute favorite wild cats: the caracal, which is fortunately labeled "Least Concern" by the IUCN.  The caracal is found all over Africa, pretty much except in the rainforests and the deserts, as you can see in the map below.  The caracal is also found in various non-African countries, such as Israel, Iran, Arabia, Jordan, Pakistan, and India.

I am not going to do a lot of talking (which is not normal, believe me), as words can't really do justice to what this cat can do.  So just click the link below, and be amazed.  (I actually have never watched this video with the audio on, so I don't even know what he is saying, because I think that the audio would simply detract from the video.  Enjoy!)

Predators of Baby Leopards: You Might Be Surprised

One of my favorite TV shows is BBC's Big Cat Diary, which I believe I have already mentioned once or twice.  It has been called by critics as "The soap opera of the Serengeti," and has played for a number of seasons, under various other titles.  Essentially, the shows premise is a log of what two prides of lions (the Marsh and Ridge Prides) are doing, as well as my two favorites, the leopards and the cheetahs.

This is neither a leopard nor a cheetah, but a baboon skeleton.  It's probably poor planning on my part to not put a picture of what I've already talked about so far, but you're going to have to deal with it.  Or just pretend that's a cheetah, baboons and cheetahs are practically the same animal anyways.

In one episode I was recently watching, one of the co-hosts, Saba Douglas-Hamilton, said something that I thought was very interesting about leopard cubs.  She said that the top three animal threats to African leopards (besides humans, forcing the IUCN to label the African leopard as "Near Threatened,") are lions, hyenas....and baboons.  Check out the baboon skeleton (above) and mounted stuffed specimen from the American Museum of Natural History below!

I was actually completely kidding before, baboons and cheetahs are not really that closely related at all, and very few people have an excuse to confuse the two.

I knew baboons were an issue to leopards as one of the leopard stars of the earlier series, dubbed Half-Tail, was missing half her tail, hence her name.  The two hosts at the time, Jonathan Scott and Simon King, said that they thought the missing half of her tail was due to either a lion attack or, more likely, baboons.

Chilling like a villain: a leopard takes a break after staring out the window all day and stressing out about those stupid robins in that stupid birdbath.  Those robins better consider themselves lucky that there's glass between them, you mark my words.  Photo Credit: Ted and Gail Neher

I had never really thought about it before, but when I heard Saba mention it, I thought that was kind of strange.  Well, I looked up "baboon skulls" on Google Images, and I think I get it now; their canines can grow up to two inches long.  As a good comparison, the average lion typically possesses two inch long canines.  Now that is some serious dental hardware; I'm glad I'm not a baboon dentist!  (That, and I'm guessing that you don't get paid very much).

A baboon skull mounted at the American Museum of Natural History in New York City, New York.  Check out those nasty canines, they're frickin' huge!!

Baboons, like many primates (actually I believe all except for tarsiers), are omnivores, so theoretically they could use their canines to subdue and consume their prey.  However, it seems that male vs. male competition is the primary reason why baboons have such enormous canines.  Check out the "mandrill" webpage on the website for Bone Clones (for the lazy amongst you, HERE is a link), and you can see that the male has enormous teeth, while the female has a dentition that is much less impressive.  This seems to support the idea that baboons (at least the males) primarily use their teeth in interspecific intimidation, in order to frighten off other males and secure breeding rights to the females.
