Marsh Rice Rat

Oryzomys palustris
The Marsh Rice Rat is one of the most common mammals found near the Atlantic and Gulf coasts. There are around half a dozen different location-based subspecies that ranged from Texas to New Jersey.

Water is of no concern to the Marsh Rice Rat. As the name may suggest, they are right at home in wet and swampy waters. They have water repellent undercoats, are able to dive underwater, and they have been observed swimming distances of up to 300m!

Marsh Rice Rats breed almost year round, and produce litters of up to five offspring who are weaned and on their own in just three weeks. The Rats are prolific opportunistic feeders, snacking on snails, fish, turtles, and bird eggs among other things. Due to their nocturnal nature, however, they are frequently prey for Owls.

Size : Length 9in (23cm)

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

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


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!
