Walking Catfish

Clarias batrachus
Today we're going to be learning about yet another animal that has entered the pet trade... but with some damaging results.

Walking Catfish in their native environment aren't all that bad. They hail from Southeast Asia, and live in a variety of freshwater habitats. They can even be found in waters that other fish will not tolerate well, like canals, flooded areas, and even in brackish zones.

The common name of this species come from the fact that they can "walk" across land. Their pectoral fins allow them to stay upright while they move outside of the water. The movement is far from graceful, but it does let the fish move between different bodies of water.

Walking Catfish are omnivores, and use their barbels to hunt around for anything and everything. They are generalist feeders, consume plant matter, eggs, small fish, and invertebrates. The Catfish themselves are fished for food in their native range.

Back in the 1960s, individuals in the pet industry decided to bring Walking Catfish to Florida. Fish either escaped or were intentionally released into the wild, and now they are considered a dangerous invasive species. They are hurting local fish farms as well as the native species, due to their ability to move outside of water, their hardy disposition, their voracious appetite, and the fact that they carry Enteric Septicemia (ESC). Since the 1960s they have also moved into a handful of other states as well. It is now illegal to own one of these fish in the United States without a federal permit.

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
