Richmond Birdwing

Ornithoptera richmondia
The Richmond Birdwing is one of the smallest species of Birdwing Butterfly... though they are still quite large as far as Butterflies go-- their wingspan can get as large as 15cm. Males and females differ in appearance. The female are larger, but have plainer, brown-grey wings. Males have black wings, but with bright, iridescent blues and greens. Both sexes have red on their thorax.

They are endemic to Australia, and as larvae they normally feed on two specific plants that are also endemic to the continent, Pararistolochia praevenosa and Pararistolochia laheyana. Those larvae need very specific conditions to survive, which is why the Butterflies live in only a very specific range (and are rare-sighted). The larvae require soft plants (like those listed above) to feed upon, but they also need a large volume of food to quell their ravenous appetite. As adults, the Richmond Birdwings are strong fliers, and are often found high up in the canopies, coming down only to feed or lay eggs.

The Richmond Birdwing has not been officially listed by the IUCN, but they are considered locally vulnerable in a few areas, but stable in others. Because their larvae have specific needs, habitat loss and the loss of native plant life are major concerns.

IUCN Status : Not Listed
Location : Australia
Size : Wingspan up to 15cm
Classification : Phylum : Arthropoda -- Class : Insecta -- Order : Lepidoptera
Family : Papilionidae -- Genus : Ornithoptera -- Species : O. richmondia

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!

Banggai Cardinalfish

Pterapogon kauderni The Banggai Cardinalfish is a small tropical fish that is becoming very rare in the wild, even though it has been successfully bred in captivity. You will only find these small, 3in long fish around the Banggai Islands of Indonesia. They are the only members of their genus, and you can tell them apart from other Cardinalfish by their three-striped bodies, tasseled first dorsal fin, long second dorsal, and their deep-forked tail fins. Banggai Cardinalfish are diurnal and live in small groups of about a dozen members. They are opportunistic feeders who dine on whatever smaller plants and animals they can find. Courtship and mating is pretty interesting for these guys-- females are the ones who initiate. They isolate a male and the pair will perform various courtship rituals before spawning. The Cardinalfish are mouthbrooders, which means that the males take the fertilized eggs (up to 90 of them) into their mouths and incubate them for up to 30 days. During t...
