Discus Cichlids

Symphysodon aequifasciatus   
Today's animal is actually.. well... three animals. There are three species of Discus Cichlids, all of which live in the Amazon River Basin, all of which have compressed, disc-like body shapes, and all of which have some really neat colors and patterns.

There is a little bit of controversy over how the three species are named and identified. There are two general camps, and both agree that there are three different species within the genus, but there is confusion over the classification. One group claims that S. discus  and S. aequifasciatus are close relatives, and a newly discovered species, S. tarzoo, is different due to its spots. Of course, a year after that finding was published another report came out arguing that S. tarzoo is actually S. haraldi, and that Haraldi adn Discus may have formed hybrids.

I'm confused just writing all that. And it doesn't help that these two studies give the same common names for different fish. The Green Discus is apparently both S. tarzoo and S. aequifasciatus! Anyway, for a little more clarity on the great Discus debate, check out this full article.

Discus Fish are popular in aquariums, and their farming has becoming quite a large industry in South Asia. Their bold coloring and interesting shape attract aquarists around the world. They also, like many Cichlids, have an interesting parenting style. While most fish lay their eggs and leave, both Discus Fish parents care for their larvae, even producing a secretion from their skin that their young can feed off of!

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.
