Goliath Grouper

Measuring in at lengths of up to 8ft (2.5m), the Goliath Grouper (Epinephelus itajara) certainly lives up to its name. This giant, which tips the scales at around 800lbs (360kg), is found in the tropical Atlantic waters off of West Africa and the Americas, and in the Pacific from California to Peru. They are the largest members of the family Serranidae.

Goliath Groupers have large, stocky bodies that are nearly half as wide as they are long. Adults sport small spots across their greenish-brownish-greyish scales, and smaller individuals tend to have vertical bars down their sides.They have three to five rows of teeth in the lower jaw, though they are rarely used. Groupers are carnivores and consume fish and crustaceans, but they swallow their prey whole. While young, Goliath Groupers are preyed upon by other fish, but once full grown Sharks and Humans are their only real predators.

Goliath Groupers have a long lifespans; they reach sexual maturity around 6 years and it is believed they can live as long as 50. They are typically solitary fish, sometimes living in small groups, but during the breeding season they congregate in schools of 100 or more. Reproduction takes place via spawning, and the eggs are dispersed into the water currents. Newly hatched Goliath Grouper larvae are very small and kite shaped, and will reach juvenile form a month after hatching, when they reach about 1in (2.5cm) in length. Many other Grouper species exhibit hermaphroditic tendencies, with the fish ages as females before becoming male. This is not confirmed in the Goliath Grouper species.

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!


The Binturong ( Arctictis binturong ) also has an equally awesome alternate common name, the Bearcat! However, it really isn't much of a bear OR a cat. While it is true that it is part of the Feliforma suborder, it is not a member of family Felidae. Binturongs are a part of their own family, Viverridae, which is shared with Civets, Linsangs, and Genets. There are six subspecies of Binturong, all of which have slight differences based upon location and habitat. Binturongs range in body size from 60-100cm in length, (not including their tail which has roughly the same length) and weigh between 20 and 30lbs. Binturongs are nocturnal animals native to the rain forests of South East Asia. The species range spans through several countries including China, Malaysia, Indonesia and the Philippines. They are tree dwelling mammals, and have fully prehensile tails that basically double their body length and can be used to cling to the trees or to grasp food. Binturongs are phe
