Gastric-Brooding Frog

Gastric-Brooding Frog regurgitating her young
There were once two species of Gastric-Brooding Frog; two remarkable creatures with a unique trait that went extinct as recently as the 1980s. At the time of their disappearance both species had very limited ranges in Queensland, Australia. The exact cause of their extinction is not completely understood, but habitat loss, disease, and illness most assuredly played their parts. The last Gastric-Brooding Frog was seen in 1981, and unsuccessful searches have been carried out to locate them since them.

What makes Gastric-Brooding Frogs so special is that they were the only Frogs in the entire world that incubated their eggs inside the mother's stomach. That's right, after laying her eggs, and having them fertilized by a male, the female frog swallows them all. During the 6 to 7 week incubation period the female does not eat. This is what keeps her from completely digesting her offspring.

Also amazing is the fact that the offspring go through a complete metamorphosis at this time. They never live as Tadpoles in the outside world, having moved through that process in the mother's stomach. When she regurgitates them, the young frogs hop away on their own and have no further contact with their parent.

    I'm not surprised!

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
