Pelican Eel

(Image Source)
Pelican Eel, Umbrella Mouth Eel, Gulper Eel, Eurypharynx pelecanoides, no matter what you call it, this is one strange looking animal. Pelican Eels are so named because of their absolutely gigantic mouths. They are found in rather deep waters, between 3,000 and 26,000 feet, of both tropical and subtropical waters around the world.

Pelican Eels can grow up to a meter in length, with a large portion of that taken up by its massive head. Their mouths have hinged jaws that would allow them to eat fish much larger than themselves. Their stomachs stretch as well, though interestingly, they have very small teeth. This, combined with found stomach contents, demonstrates that Pelican Eels primarily eat small crustaceans.

Another rather interesting part of their body is the long, whip-like tail. Pelican Eels have long tails that are tipped with bioluminescent photophores. It is believed that these serve a purpose to lure prey in the dark, deep water.

Not much else is really known about these strange fish. They live so far down that we only really get to study specimens that get accidentally caught by fishermen. They have need been evaluated by IUCN.

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...
