I'm sure you've heard of hybrids like Ligers and Mules, but what about Wholphins? They are the result of crosses between two ocean-dwelling mammals- Bottlenose Dolphins and False Killer Whales. I should note, however, that the False Killer Whales (like regular Killer Whales) are members of the Oceanic Dolphin family along with the Bottlenoses, so the relationship isn't as far off as one might think.

While this hybrid might appear in the wild, we only know of them definitively from two individuals living at Sea Life Park in Hawaii. Back in 1985 a female Bottlenose and a male False Killer Whale lived in the same tank, and were performers in the park's aquatic show. No one expected the 14ft Whale and 6ft Dolphin to mate, but the surprise result was Kekaimalu. She herself actually gave birth to a 3/4 Bottlenose offspring in 2005 (She had two previous calves, one died shortly after birth, and one lived till the age of 9). That makes Kekaimalu and Kawili Kai the only known captive Wholphins in the world.

Wholphins are interesting because they area true mix of the species. They grow to a size somewhere in between that of the two species (Kekaimalu's calf was the size of a 1-year-old Bottlenose when she was but 1 month old!). They have an intermediate gray color, and their teeth also fall right down the middle- False Killer Whales have 44, Bottlenose Dolphins have 88, but Kekaimalu has 66!

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
