20 Makhluk Paling Menakutkan yang Masih Hidup di Bumi

1. The Angler Fish

Spoiler for pic:

The angry-looking deep sea anglerfish has a right to be cranky. It is quite possibly the ugliest animal on the planet, and it lives in what is easily Earth's most inhospitable habitat: the lonely, lightless bottom of the sea.
There are more than 200 species of anglerfish, most of which live in the murky depths of the Atlantic and Antarctic oceans, up to a mile below the surface, although some live in shallow, tropical environments. Some angler fish can be quite large, reaching 3.3 feet (1 meter) in length. Most however are significantly smaller, often less than a foot.

2. The Wolf Fish

Spoiler for pic:

In spite of its large size the Atlantic wolffish has retained the bodily form and general external characteristics of small blennies (Blennioidei). The largest specimen recorded measured 150 cm (almost 5 ft) long and weighed almost 18 kg (40 lbs)[3] Its body is long, subcylindrical in front, compressed in the caudal portion, smooth and slippery, the rudimentary scales being embedded and almost hidden in the skin. Atlantic wolffish vary in color, usually seen as purplish-brown, a dull olive green, or blueish gray.

3. The Camel Spider

Spoiler for pic:

1. Camel spiders can move at speeds over 30 MPH, screaming while they run.
2. Camel spiders can be as large as a frisbee.
3. Camel spiders venom is an anesthetic that numbs their prey.
4. Camel spiders can jump three feet high.
5. Camel spiders get their name because they eat the stomachs of camels.
6. They eat or gnaw on people while they sleep. Due to the numbing effect of their venom, the victim is unaware until they awake.

4. The Viperfish

Spoiler for pic:

The viperfish is one of the most unusual-looking fish in the deep sea. It is also one of the most popular and well-known species. Known scientifically as Chauliodus sloani, it is one of the fiercest predators of the deep. This fish can be easily recognized by its large mouth and sharp, fang-like teeth. In fact, these fangs are so large that they will not fit inside the mouth. Instead, they curve back very close to the fish's eyes. The viperfish is thought to use these sharp teeth to impale its victims by swimming at them at high speeds.

5. The Aye Aye

Spoiler for pic:

Aye-ayes can be found only on the island of Madagascar. These rare animals may not look like primates at first glance, but they are related to chimpanzees, apes, and humans.
Aye-ayes are dark brown or black and are distinguished by a bushy tail that is larger than their body. They also feature big eyes, slender fingers, and large, sensitive ears. Aye-ayes have pointed claws on all their fingers and toes except for their opposable big toes, which enable them to dangle from branches.

6. The Sun Spider

Spoiler for pic:

Their arms are sticky, which are used to hold their prey items while they eat them. Only the last pair of legs is used for walking.
The abdomen is rounded and the tail has no stinger of any kind, which makes it different from others of its species.
Females lay eggs in a burrow they dig in the sand.
They will lay about fifty eggs at a time and guard them with veracity until they hatch. The small sun spiders are active only at night, while the adults are more active at night but will also hunt and move around in daylight hours.
Windscorpions, or sun spiders are predators, but they have no poison to help them catch their prey.
They are very aggressive hunters, stalking and capturing prey in their arms rather than with poison. They eat insects, and some smaller animals such as lizards who are many times larger than the predator.
Sun spiders live independently of each other, and only the females with young will live in a group. They are very often regarded as beneficial because they feed on insects and can keep homes insect free.
Their harmless nature to man further discourages any control.

7. The Gharial

Spoiler for pic:

DISTRIBUTION:
Northern India subcontinent: Known populations exist only in India and Nepal. It is now considered very likely that historical populations in Bangladesh, Pakistan, Bhutan and Myanmar are extirpated.
Remaining populations in India are found in the Chambal River (<100 adults in National Chambal Sanctuary), Gitwa River (20-30 adults in Katernia Ghat Sanctuary), Son River (<5 adults in Son River Sanctuary), Mahanadi River (<5 non-breeding adults in Satkosia Gorge Sanctuary) and around 40 non-breeding adults in the Ken, Ramgenga, Yamuna and Brahmaputra rivers. Remaining populations in Nepal are found in Narayani/Rapti River (<10 adults in Chitawan National Park) and around 30 non-breeding adults in the Karnali, Babai and Koshi rivers.

8. The Jumping Spider

Spoiler for pic:

Jumping Spider, common name for any of a group of hunting spiders that can leap 10 to 40 times their body length. With over 4000 described species, they comprise the largest family of spiders. Jumping spiders are particularly diverse in tropical regions, but occur in habitats ranging from rain forests to above the timberline on Mount Everest in the Himalayas. More than 300 species have been described in the United States.

9. The Mouse Spider

Spoiler for pic:

There are eight species of mouse spiders in Australia and they are widely distributed across the mainland. They vary from 10 mm - 35 mm body length and all have distinctively bulbous head and jaw regions. They are often confused with funnel-web spiders. While mouse spider bites are not common, a few have caused serious effects in humans, with symptoms similar to funnel-web spider envenomation. Fortunately, mouse spiders are not usually abundant in heavily populated urban areas.

10. The Spicebush Swallowtail Caterpillar

Spoiler for pic:

Adults can be identified by their spoon-shaped tails and by their bright green (male) or iridescent blue (female) hind-wings. Ivory spots may be visible on the forewings, and orange spots may appear on the hindwings. Wingspan may be 3 to 4 inches.

11. The Praying Mantis

Spoiler for pic:

Mantises have two grasping, spiked forelegs ("raptorial legs") in which prey items are caught and held securely.

12. The Blue-eyed Dragonfly

13. The Giant Isopod

Spoiler for pic:

Looking like it just crawled out of a bad science fiction movie, the giant isopod is without a doubt one of the strangest creatures found in the deep sea. Known scientifically as Bathynomus giganteus, it is one of about nine members of the genus Bathynomus. It is also the largest known members of the isopod family, a group of crustaceans closely related to shrimps and crabs. The giant isopod is also related to the small pillbugs that you can find in the garden

14. The Frilled Shark

Spoiler for pic:

The frilled shark (Chlamydoselachus anguineus) is one of two extant species of shark in the family Chlamydoselachidae, with a wide but patchy distribution in the Atlantic and Pacific Oceans. This uncommon species is found over the outer continental shelf and upper continental slope, generally near the bottom though there is evidence of substantial upward movements. It has been caught as deep as 1,570 m (5,150 ft), whereas in Suruga Bay, Japan it is most common at depths of 50–200 m (160–660 ft)

15. The Dragonfish

Spoiler for pic:

The deep sea dragonfish, sometimes known as the scaleless dragonfish, is a ferocious predator that inhabits the deep oceans of the world. Known scientifically as Grammatostomias flagellibarba, it has extremely large teeth compared to its body size. In spite of its gruesome appearance, its is a small fish, measuring only about 6 inches (about 15 centimeters) in length

16. The Giant Grenadier

Spoiler for pic:

The giant grenadier, Albatrossia pectoralis, is a deep-water benthopelagic macrourid found in the North Pacific Ocean and the Bering Sea in depths of 200 to 2170 meters. Few macrourid species are commercially targeted by United States fisheries, but in the Gulf of Alaska and Bering Sea many are caught incidentally by trawl and longline fishermen. To properly manage the fishery, age and growth information is needed. The most common method of age determination involves counting growth increments deposited in calcified structures such as otoliths (fish ear bones).

17. The Blobfish

Spoiler for pic:

The Blob fish is a type of fish found off the coast of Australia and Tasmania but don’t expect to see one on your holidays as they are extremely rare to come by. The reason the Blob fish is so rare is that they live very deep down in the sea, literally just off of the sea bed. The Blob fish are found at a depth of around 800 meters which would make life impossible for most fish as at that depth the pressure is roughly eighty times more than at sea level..
