While scientists have already recorded around 1.2 million animal species, they are convinced that there are at least 8.7 million more species left to discover. The animal kingdom is diverse and marvelous. From long-nosed monkeys to long-legged crabs, here are some of the world's most unique creatures.
Scientific name: Carlito syrichta
Range: islands in Southeast Asia
The tarsier is named after its unusually long tarsals (ankle bones). These nocturnal primates are known for their lemur-like appearance and bulging eyes. They are carnivorous and have padded digits, which allow them to grip onto tree trunks while they move through the forest.
Scientific name: Ambystoma mexicanum
Range: lakes near Mexico City
This salamander has a long tail, external gills, and short legs. They are usually a darkish brown with black speckles. However, white and albino Axolotls are also common. In Mexico City, where these unique amphibians are found, they are considered edible.
Scientific name: Trachelophorus giraffa
Range: forests of Madagascar
This insect was only discovered in 2008, so our knowledge of them is limited. However, we do know that they are herbivorous and that they do not sting. They have long giraffe-like necks, with males having necks two to three times the size of a female's.
Christmas Tree worm
Scientific name: Spirobranchus giganteus
Range: on coral in the Caribbean and throughout the world's tropical oceans
The Christmas Tree worm is a unique species of tube worm found under the sea. They are known for their Christmas tree-like appearance and bright colors. Their tentacles, which give them their conical shape, allow them to eat and breathe underwater. When disturbed, these worms retract back into their tubes.
Scientific name: Monodon monoceros
Range: Canadian Arctic, Greenlandic, Russian waters
This unique marine mammal is most popularly known as the "unicorn of the sea". They have long tusks that can reach up to a meter (3 feet). The Narwhal tends to live in groups and they are usually found along the coasts or in rivers.
Scientific name: Cacajao calvus
Range: trees in the Amazon basin
The Bald Uakari is a red-faced primate native to South America. They prefer to live in flooded rain forests or near lakes and rivers, where water is plentiful. These mammals are herbivores, known to spend the day foraging for fruits and leaves. Unfortunately, due to hunting and the timber industry, their population is being threatened.
Scientific name: Nasalis larvatus
Range: along rivers and in the mangrove forests of Borneo
These primates are famous for their drooping nose. While both female and male Proboscis monkeys have a sagging nose, males have larger noses. Males also weigh twice the amount of a female Proboscis monkey. They are reddish brown and have long tails.
Japanese spider crab
Scientific name: Macrocheira kaempferi
Range: Pacific waters near Japan
These intimidating crustaceans have an orange body with white spotted legs. They prefer the deeper parts of the ocean, foraging for foods such as shellfish, algae and fish on the sea bed. Japanese spider crabs use their pincers to tear apart the meat of their prey. This spider-like sea bed crawler is one of the largest arthropods. Their leg span can reach up to 12 feet (3.7 meters).
