Northern Snakehead

Channa argus
The Northern Snakehead is a fish that is originally found in China, Russia, North Korea, and South Korea. However, in the past decade or so they have also made their way over to the United States and Canada, where they are considered to be an invasive
species.

You can identify a Northern Snakehead by its large mouth, very long dorsal fin, and a rounded tail fin. They come in shades of brown, with both lighter and darker blotches.

Northern Snakeheads are excellent hunters, with no natural predators of their own. Which is why their introduction to non-native areas has been so damaging. They disrupt the normal food chain and threaten the livelihood of other species. In North America, the fish have been both intentionally and unintentionally introduced, and have been found from Florida all the way to British Columbia.

One reason they are so hard to contain is the fact that they can breathe air, and can survive out of water for long stretches of time. This means that they have the ability to move between nearby bodies of water by wiggling their bodies.

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

Four!

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!
