I feel like this might be a little bit of a cheat here, since I did actually cover Moas before, albeit in a very general fashion. Today though, I'll be talking about one specific species of Moa, the Upland Moa, which was the smallest of the species, as well as the last to go extinct.

Upland Moas, as the name suggests, lived in the higher, cooler elevations of New Zealand's South Island. One remarkable feature of this species is that they are the only Moas to have feathers all the way down their legs and feet. The feathers and their small size were adaptations to their cold weather environment.

Mummified Moa Head
How do we know about these feathers? Mummification of course! Because Upland Moas lived in such cold, dry habitats, their bodies have been subject to the process of natural mummification. We have examples of mummified Upland Moa heads and feet, which allow us to know more about the species than mere bones would. For example, we know from these specimens that Upland Moas had small olfactory chambers, which means that they may have had greater vocal skills then other Moas.

Their high elevation habitat is probably what allowed these birds to live longer then the other Moas. They only had one predator before the arrival or man, the Haast's Eagle, and due to their remote location it took humans longer to find and hunt them. They went extinct sometimes around 1500CE.

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...

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills. IUCN Status :  Not Listed ...

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!
