The venom comes from a gland in the elbow and, like a party trick invented by Dracula, is ejected through the teeth.
This venom, however, isn't enough to save the slow loris from the dangers of the pet trade; it's listed as endangered on the IUCN Red List.
There are five distinct species of slow loris, including the Bornean slow loris, which can be found on the island of Borneo and spotted with the help of Borneo Eco Tours.
Maybe bulging eyes, slightly down-turned mouth, curly, prehensile tail and extremely long tongue, the chameleon is one of the more appealing reptiles.
As remarkable as its color-changing mood swings is the peculiar way chameleons move in a rocking motion.
Not the most efficient way of transportation, but definitely attention-grabbing.
About half the world's chameleons can be found in Madagascar. Terra Incognita Ecotours runs 15-day trips for $5,599 per person.
Meerkats are a type of mongoose that live in the deserts from the Kalahari of Bostwana to the Namib of Namibia, South Africa and parts of Angola.
With meerkats it's not so much their faces, which, while far from ugly, are really no different from those of the common dwarf mongoose.
It's the way they stand, the human-like upright pose with paws gathered demurely at the front.
Self-described "safari specialists" Somak Holidays runs meerkat expeditions called Meerkat Madness that cover the Kalahari and Namib deserts.
Meerkat Adventures specializes in short treks to meerkat grounds for 550 rand ($70).
Koalas aren't as sweet as they look.
Koala experts say the creatures' behavior most often varies between mildly cranky to downright bad-tempered.
The koala's enduring popularity indicates that, as in our love lives, good looks can blind us to severe personality flaws.
At the Lone Pine Koala Sanctuary in Brisbane, Australia, guests can pet koalas -- hopefully one of the better-tempered ones.
For the best chance of glimpsing a koala in the wild, you need only to book a trip to Australia's Otway Coast, where koalas can be found chilling by the Grey River, Kennett River, Wye River and Wongarra.
From "Mr. Popper's Penguins" to "Happy Feet," the squat, aquatic birds with their sleek, debonair coats have a secure position in pop culture.
There are 17 species of penguins in the world. Most are some version of black and white, none can fly and all are excellent swimmers.
What's more surprising is that penguins are also excellent runners.
Six of the 17 species live in Antarctica, so the most enjoyable way to call on these birds is through a cruise in the region.
