Hispaniolan Solenodon

Alright so. The Hispaniolan Solenodon (Solenodon paradoxus) is considered to be one of the best examples of what mammals looked like during their beginnings over 70 million years ago. The ancestors of this shrew-like creature branched off from other mammalian families during the late Cretaceous period, and the extant Hispaniolan Solenodon is now one of the last few remaining native mammal species in the Caribbean. Literally dozens of mammal species existed on these islands prior to human colonization, but now due to loss of habitat and increased predation from introduced species populations, only around fifteen remain.

The Hispaniolan Solenodon is unique to the island of Hispaniola, were it can be found in a multitude of habitats... well, that is, if you can find them. They are very difficult to locate in the wild, and at times many believed them to be extinct. Conservation efforts have been ongoing between various government agencies, zoo organizations, and the EDGE program. EDGE brings awareness and conservation to some of the rarest and most genetically unique mammal and amphibian species in the world. The Hispaniolan Solenodon is an EDGE Focal Species.

What makes the Hispaniolan Solenodon so unique? Well, aside from the 76 million year old evolutionary split, they are one of only a few mammals that can produce toxic saliva. This mechanism is used to capture their insect prey and is something that was more commonly found in prehistoric mammals. The venom is injected through their lower incisors. Solenodons are about the size of rats, are nocturnal, and live in family groups that consist of a breeding pair and one to two offspring. Only one case of captive breeding has ever been documented. Their life expectancy in the wild is unknown, but one captive individual lived eleven years, which places them as relatively long lived small mammal. Traditionally they only had three major predators, the Barn and Stygian Owls, and the Hispaniolan Boa. Today, feral dogs and cats, as well as mongoose introduced to the island, have hurt their numbers considerably. More information about this fascinating creature and its conservation can be found at EDGE and at The Last Survivors project.

Thank you so much to @greenantilles for the wonderful suggestion!

Greater Kudu

Tragelaphus strepsiceros The Greater Kudu is one of the largest Antelope species out there, which the largest males standing over 5ft tall at the shoulder and weighing over 600lbs. They sport horns that equally as impressive in size-- the record is 72in. You'll find the Greater Kudus in southern and eastern Africa, where they inhabit scrub woodlands. Their brown coloration and white stripes allow them to remain camouflaged within these woody surroundings. The Kudus are most active at dawn and dusk, and spend the daytime hours hidden in these forested areas. However, their stripes are not their only defensive mechanism; they also sport very large ears that allow them to hear approaching danger. When alerted, the Antelope can try and bound away to safety. Female Greater Kudus tend to live in moderately sized groups with other females and offspring. Most mature males are solitary, and will only join up with these herds during the breeding period that corresponds with the end

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!
