The American Lobster, as its name might suggest, can be found in the waters of the Atlantic, running from Canada down to the Carolinas. They do not swim, instead they move about by crawling thanks to four pairs of walking legs. The fifth pair, (or rather, the first if going from head to tail) makes up the large claws.

Molting is a very important activity in the life of a Lobster. As they grow towards adulthood, juvenile Lobsters will molt their carapace multiple times a year. They essentially grow a whole new shell under their old one, and then seek out a safe place to shed. The Lobsters are vulnerable for a time after their old shell has been discarded, because the new one is still soft. It will harden over time, and adult Lobsters molt about once a year.

Molting has a big part in Lobster reproduction, as females can only mate when their new carapaces are soft, right after molting. They can lay thousands of eggs at once, which are carried on the underside of the female's tail for as long as a year!

American Lobsters are opportunistic feeders. They dine on Plankton, Mollusks, Fish, Algae, Worms, and even other Lobsters. They have also been known to consume their own recently molted shells!

The harvesting of American Lobster is a $300,000,000 industry, and overfishing exists in some areas of southern New England. Measurements are in place by the NOAA that outline the protection of breeding females, the minimum size a Lobster must be at to be caught, and what types of traps can be used. The largest American Lobster ever caught weighed 44lbs (20kg).

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


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
