Did you know that  Goldfish were one of the first fish species to be domesticated? It happened nearly 1,500 years ago in China, where they took rather plain looking Asian Carp and bred them down. They spread to Japan in the 15th century, and were in Europe by the late 17th. Domesticated Goldfish can now be found all around the world!

There are dozens of different Goldfish varieties, coming in all sorts of shapes and sizes. Orange, black, white, and speckled are all common colors. Tail shape is also highly variable, with some being short and blunt and others growing quite long and flowing.

Did you know that there is a reason why Goldfish nibble at tiny bits of food all day? This is because they don't actually have a stomach in which to store food during digestion. Because of this, they have to eat very small amounts several times a day.

Another interesting fact about these popular fish is that they don't actually have three second memories. This misconception has been debunked by scientists and even by enterprising young Australians. Goldfish have the ability to store and recall information, and are able to recognize food and predators just like any other creature.

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!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
