Abyssal Grenadier

Coryphaenoides armatus
Today's animal is one of those deep sea fish that we so uncommonly see alive. Even though they live in all of the world's oceans, the Abyssal Grenadiers normally hang out between 1,000 and 15,000 feet down!

These fish are abundant in the dark depths of the oceans. As adults they can grow nearly a meter in length, though smaller sizes are more common. They feed on other fish, sea urchins, crustaceans, and cephalopods.

Abyssal Grenadiers have a very distinct look to them. They have large heads (featuring large eyes) but bodies that taper out into a tail that completely lacks a caudal fin, along with spined fins that run down both their dorsal and central sides. These fish are known to be very slow-growing, and live as long as 60 years.

Amazingly, while many fish species are suffering, the Abyssal Grenadier populations are booming! They live so far down that they aren't affected by the fishing industry, and between 1989 and 2004 they doubled in number. Scientists don't know much else about them though. Their reproductive habits are unknown, and they have never been kept in captivity.

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!

10 Years?!

My goodness! It's been 6 years since I went on hiatus, and now more than 10 years since AaD was born, and what a world we've moved in to! Animal a Day is coming back- but in the meantime, check us out on Facebook, for your daily dose of #BIRDNEWS
