Eastern Newt

Notophthalmus viridescens
Eastern Newts can be found in the Eastern United States, where they have a range that spans all the way from southern Canada down to Texas. They live in fresh bodies of water, typically near forest areas.

Eastern Newts go through some pretty interesting life phases. Adults will mate on land during the early spring, and the female will lay up to 400 eggs a season, one at a time,  in the water. The eggs are attached to aquatic plants, and will hatch in anywhere from 3 to 8 weeks, depending on the temperature.

Larval Newts look just like their adult selves, only much much smaller. They measure only about 7mm long! The larvae spend their summer eating as many little invertebrates as they can. When late summer comes around they metamorphose into their Juvenile or "Eft" form.

Eft Phase
Efts look different from the adults and larvae. For one, they completely lose their gills in favor of a set of lungs. They also have thinner, less powerful tails. Efts live on land for two to four years and feed on terrestrial invertebrates like snails and springtails. They hibernate under logs and rocks during the winter. Eventually they will grow large, flattened tails and return to the water as adults.

Thanks to those tails, adult Eastern Newts are very powerful swimmers. They remain in water for the rest of their lifetimes, and will feed on just about any invertebrate that they can catch. If they make it past the high mortality larval and eft phases, Eastern Newts can live up to 15 years!

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!

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.
