Ever heard of cobras, ever heard of tarsiers? Have you ever seen the 10,000-year-old turtle, have you ever seen a marta turtle that lives in fresh water? Next, we took stock of 8 rare animals in the world, strange, some of which may have been heard but not seen.
1. Banga tarsier
Each eye of the Bunga tarsier is larger than its brain, and the large eyes of this ultra-small primate are nature's weirdest night vision goggles, and its massive feet and powerful hind legs mean it can jump from tree to tree, looking for insects and small invertebrates to eat.

Banga tarsier
Where it was found: This tarsier is native to Borneo and parts of Sumatra. There is a "grueling hike" in the Clark Mountains of Borneo, where hikers can spot gibbons, orangutans and these cute little animals.
2. Viper
The fish's head is a nightmare at a glance, and many fangs of varying lengths protrude from its terrifying mouth that resembles the "Iron Virgin", and the viper has these characteristics because it lives in the depths of the ocean at depths of 1,000 to 2,000 meters.
Discovery: You won't be able to see a live viper unless you have a sea diving ball, however, visitors to the annual Ocean Festival in Iceland's capital, Reykjarm Harbor, may be able to spot a dead viper.
Fishermen often exhibit many strange deep-sea creatures, including marine lampreys, fangtooth and squid. The Reykjarm Ocean Festival, also known locally as "sjomannadagur", is held every June.
3. Red bald monkey
The ape has a shocking red head, so south Americans gave it the funny nickname "English Monkey", in honor of the first Britons to travel to their homeland, with a red face sunburned.
Discovery: Red bald monkeys can be found deep in the forests of Brazil, Peru and Colombia.
At the Mamirawa Sustainability Conservation Area, if you're lucky, you'll be able to spot red bald monkeys. Other animals found in the nearby area include three-toed sloths, black squirrel monkeys and pink pufferfish.
4. Marta turtle
This large freshwater turtle has several strange features. It looks like a piece of water-soaked bark and debris, and it has a very strange protruding nose that acts as a diver's snorkel and helps it dive.
It eats small fish in an unusual way. The Marta tortoise will find a place to hide itself, then wait for the prey to come to the door by itself, and when the prey is very close to it, it will open its mouth and suck the fish into its mouth like a low-pressure vacuum cleaner.
Places of Discovery: Marta turtles can be found in many parts of the Amazon Basin. In the city of Iquitos, Peru, you can see toucans, dolphins, tarantulas, piranha, anacondas and marta tortoises.
5. Fog-basking beetle
This ordinary-looking beetle collects water in a very unusual way, and precipitation in the namib desert is very rare, so when the coastal mist is blown inland by the wind, the beetle will stand upside down in the desert and collect small water droplets in the air with its own hind legs.
Discovery: The Namib Desert, which is also home to the very rare Namibian chameleon.
This chameleon can make the sides of the body appear different colors, one side black and one side white, so that one side can absorb heat in the morning and the other side to prevent heat loss.
6. Lowland streaked tenrec
The Horse Island Hedgehog comes from the island of Madagascar, home to many strange creatures, including finger monkeys (aye-aye) and lemurs.
The Horse Island hedgehog, which is covered in bristles and decorated with brightly colored yellow-brown stripes, attacks animals that attempt to attack it, piercing the deadly stingers around its neck into the target.
Discovery: Madagascar's Masoara Forest National Park, home to lemurs, hedgehogs, mongooses, geckos and chameleons.
7. Salamander
The Salamander is a salamander, an amphibian of the Animal Kingdom's Peter Pan. It is in the larval stage throughout its life, which explains why it has pinnate gills and eyes without eyelids.
In addition to this, it has an extraordinary regenerative ability. After a salamander loses a leg, it quickly grows new ones, and it can even regenerate very complex body parts, including parts of the brain and spinal cord, so scientists are very interested in it.
Place of Discovery: This animal is endangered and can only be found in Lake Hodgmirko on the outskirts of Mexico city.
8. Deer and dolphin (babirusa)
It is not surprising that the deer dolphin is a legendary creature on the Indonesian island of Sulawesi, as the inhabitants of the island were inspired by this animal and produced a lot of anecdotes and demon-like masks.
Deer and dolphins sharpen their teeth in trees and attack opponents with their fangs during clashes.
Discovery: In the Adudu Nantu and Tangkoko Nature Reserves of Manado in North Sulawesi Province, where large numbers of deer and dolphins live.
