Great Diving Beetle

Dytiscus marginalis
Picking out just one Diving Beetle to talk about today was pretty tough, considering there are around 4,000 of them! Diving Beetles are members of a HUGE family, Dytiscidae, which includes 160 different genera.

The Great Diving Beetle is notable for its range, size, and incredible appetite. They can be found in various countries throughout Europe and Asia, and especially enjoy colder climates.

As larvae these insects can grow up to 2.3in (6cm) long. Though they are only about half that length as adults, they develop incredible hydrodynamic bodies that allow them to swiftly dive down into water in order to hunt and flee from their own hunters.

Great Diving Beetles will eat all sorts of things, even fish! They are carnivorous as both adults and larvae, and swim through the water, hunting out whatever living meals they can find. Adults have claws on their forelegs that let them grab on to prey. They then bite down and inject a fluid that begins to predigest the meal, which allows them to slurp up the insides. Yum!

Location : Europe and Asia

Classification : Phylum : Arthropoda -- Class : Insecta -- Order : Coleoptera

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!

Halloween Crab

Gecarcinus quadratus The Halloween Crab goes by many names, including the Red Land Crab, Whitespot Crab, and Moon Crab. I personally like Halloween Crab though, since it really reflects the interesting colors. They have black carapaces, orange-red legs, and purple claws! Halloween Crabs live in the Pacific coast mangroves and forests of Central and South America. They actually live in the forests as adults, and return to the ocean in order to reproduce. Did you know that they live as far away as 18 miles (30km)  from water? Not where you normally think Crabs to be! While living in the forest, the Crabs forage nocturnally for different plant matter, including leaves and sapling. They also dig long burrows into the ground for protection. These burrows can measure nearly 5 ft long! Halloween Crabs are sometimes kept in captivity, and can be very tricky pets due to their excellent climbing skills.
