Giant Panda

Captive Panda at the Smithsonian National Zoo
Earth Day has arrived! And in celebration let's talk about the symbol of the World Wildlife Fund and one of the most iconic conservation poster animals out there- the Giant Panda. These large mammals are endemic to China

Giant Pandas are some weird bears. And yes, they are actual, Ursidae family-member bears, though in the past there has been speculation that they belong to some other group. At any rate, they have a digestive system made for processing a carnivorous diet, but they don't eat meat. As you probably know, Pandas eat Bamboo... which is odd because they get very few nutrients from the Bamboo. The result of their unnatural diet is that they have to eat lots and lots of the grass, up to 30lbs a day, in order to get their dietary needs satisfied.

Though their digestive tract hasn't adapted to the Bamboo diet, other features of their anatomy have. Their faces are especially round because they need large back molars and strong jaw muscles in order to grind down the fibrous plant. The have also evolved a modified "thumb" on their paws. This sesamoid bone is different from the one found in other bears, and it allows the Giant Pandas to grasp onto Bamboo easier.

There are a number of reasons why the Giant Panda is so endangered. Poaching and Habitat loss were the first threats to really affect them, though some of those pressure have been alleviated with the establishment of wild preserves. There are now around 40 separate preserves in China.

Unfortunately, it has been difficult to get the Panda population to rebound, though they are getting there. They have a mindbogglingly low reproductive rate, both in the wild and in captivity. In the wild, Giant Pandas are solitary; males and females meet up for only a very brief window of time in order to mate. After the deed is done, the male goes on his way, and the female may or may not be pregnant. Even with continued successful couplings, the birth rate is only about 1 cub every two years.

Captive breeding programs ran into all sorts of problems at first. The Pandas just didn't seem to have any desire to mate, and so most early cubs born were due to artificial insemination. Some hilarious methods have been employed over the years, including have the Pandas watch "Panda Porn," aka DVDs of other Pandas mating. Males have also been given Viagra! Natural births have been happening in recent years, though artificial insemination is still frequently employed.

Seriously. Pandas eat all day. I have about
40 pictures, they are all of them eating.
The ins and outs of Captive Panda ownership are quite interesting. All Giant Pandas outside of China are technically "on loan." Foreign zoos pay the Chinese government up to $1,000,000 each year in order to keep their Pandas, and the contracts typically have term limits to them. All Panda cubs born outside of China are still property of China, and most are sent back to their native land upon reaching adulthood. Bai Yun, the female Panda at the San Diego Zoo, has had four of her five cubs returned to China, were they take part in breeding programs.

Currently there are about 300 Giant Pandas in captivity, and it is estimated that there are around 1,600 in the wild, though there may be more. While they are not the most endangered mammals out there, they are certainly one of the most iconic.

  1. I have a couple of really great (in my opinion) pictures of Giant Pandas from the San Diego Zoo, if you want to check them out!

  2. Great video! I found panda very cute animals and the activity he does are just so cute and funny.

Bornean Orangutan

The Bornean Orangutan is one of two extant Orangutan species in the world. It is the third largest primate (after Gorillas) and is the largest primarily tree-dwelling animal in the world. Males are substantially larger than females, and average at around 165lbs. Bornean Orangutans are largely solitary. A handful might live within a small range but they will seldom interact with one another. Males and females only meet up to breed, which happens only once every several years. A young Orangutan will stay with it's mother for about five years, and the females tend to go about eight years between births. That is the longest interim period of any animal! Sadly, the Bornean Orangutans are in a lot of trouble. They need large forests in order to thrive, and deforestation and habitat degradation has left many homeless. They are also hunted for meat and for traditional medicines. Conservation areas are being established to help these guys in the wild, and it is believed that there are a


For anyone who was counting, yesterday was our birthday-- four years! Four years filled with animals from A to Z, more than 1,100 of them! I can't thank my readers enough, it's been wonderful! And in celebration of that milestone... I'm taking a break. Hopefully not forever, but for a little bit at least. In the mean time I plan on getting a new layout out, along with some updates to some of the older articles. I'll post updates here and on the Facebook page, I'm also brainstorming some new animal-related projects, so keep an eye out! Thanks again for four awesome years!


The Binturong ( Arctictis binturong ) also has an equally awesome alternate common name, the Bearcat! However, it really isn't much of a bear OR a cat. While it is true that it is part of the Feliforma suborder, it is not a member of family Felidae. Binturongs are a part of their own family, Viverridae, which is shared with Civets, Linsangs, and Genets. There are six subspecies of Binturong, all of which have slight differences based upon location and habitat. Binturongs range in body size from 60-100cm in length, (not including their tail which has roughly the same length) and weigh between 20 and 30lbs. Binturongs are nocturnal animals native to the rain forests of South East Asia. The species range spans through several countries including China, Malaysia, Indonesia and the Philippines. They are tree dwelling mammals, and have fully prehensile tails that basically double their body length and can be used to cling to the trees or to grasp food. Binturongs are phe
