Leptofoenus pittfieldae

Leptofoenus pittfieldae is an interesting animal, because it is only actually known from one single specimen. It is an extinct species of wasp that lived in the Miocene Epoch between about 5 and 23 Ma.

The Dominican Republic is known for its Amber. Many deposits have been found there, several containing specimens, such as our single L. pittfieldae. It is a male wasp, about half an inch long, and was discovered in 2008. It was determined to be a new species due to markings, wing shape, and antennae structure, among other things. It was studied at the University of Kansas natural History Museum by Dr. Michael S. Engel. Its species name, pittfieldae, comes from the name of the niece of the specimens donor.

L. pittfieldae  is the only member of its genus found anywhere in the fossil record, though their are five living species. All of those species are uncommon in the West Indies, which may point to why only one example of L. pittfieldae has ever been found; it was uncommon in that area as well.

I chose this animal today because it just goes to show that there are things out there that we may have never known about. This particular wasp was only discovered two years ago and is known only from one tiny specimen. How many other fascinating creatures of the past are still undiscovered?

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...
