Are there any harmless animals in the world? While some animals can be terrifying and dangerous, there are many animals that are harmless to humans and other animals. In fact, some animals are so harmless that they don’t prey on other animals, don’t typically attack other animals, raid their nests, or otherwise cause destruction.

These animals have calm, peaceable natures and are safe around other animals. To compile a list of the top 10 most harmless animals in the world, we looked at animals that fit these criteria. The harmless animals on our list are calm, peaceable, and just want to be left alone to feed, sleep, and raise their families.

Here are the top 10 most harmless animals in the world according to the search results.


Top 10 Most Harmless Animals In The World

Giant African Millipede


The giant African millipede, also known as shongololo, is the largest extant species of millipede in the world. It can grow up to 33.5 centimeters (13.2 inches) in length and 67 millimeters (2.6 inches) in circumference, with approximately 256 legs. The number of legs changes with each molting, so it can vary according to each individual.

Giant African millipedes are native to subtropical western Africa and love warm, dark places on the rainforest floor. They have a life expectancy of about 7-10 years.

These millipedes are quite docile and slow-moving, making them safe to handle. They have two main modes of defense if they feel threatened: curling into a tight spiral exposing only the hard exoskeleton, and secretion of an irritating liquid from pores on their body. This liquid can be harmful if introduced into the eyes or mouth, so it’s important to handle them with care.

Giant African millipedes are divided into segments, and each segment has two pairs of legs. They are herbivores and feed on decaying plant matter.



Butterflies are insects that have large, often brightly colored wings, and a conspicuous, fluttering flight. They are the only group of insects that have scales covering their wings, although some butterflies have reduced scales. Butterflies belong to the order Lepidoptera, which means “scaly wings” in Greek.

The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago. Butterflies are nearly worldwide in their distribution and are complex creatures with many day-to-day activities. They are cold-blooded, meaning they rely on external sources of heat to regulate their body temperature.

The vision of butterflies appears to be excellent, especially within short distances. Butterflies are herbivores and feed on nectar from flowers. They are important pollinators and play a vital role in the ecosystem. The most distinctive physical features of the butterfly are its club-tipped antennae and its habit of holding the wings vertically over the back when at rest.

The butterfly is also a symbol of being transgender, because of the transformation from caterpillar to winged adult.


Llamas are domesticated South American camelids that have been used by Andean cultures as pack animals and for their wool since the pre-Columbian era. They are social animals and live with others as a herd. Llamas can learn simple tasks after a few repetitions and can carry about 25 to 30% of their body weight for 8 to 13 km (5–8 miles) when using a pack.

Llamas were domesticated from guanacos in the Andean Highlands of Peru 4,000-5,000 years ago and are among the oldest domestic animals in the world. They are primarily used as a beast of burden, but also provide native herdsmen with meat, fiber for clothing, hides for shelter, and manure pellets for fuel.

Llamas are willing pack animals but only to a point. An overloaded llama will simply refuse to move. Llamas are a modified ruminant with a three-compartment stomach and chew their cud like cattle and sheep. Due to their low protein requirement and efficient digestive system, llamas are economical to feed.

Llamas are the largest of the four lamoid species and can carry a load of 45–60 kg and average 25 to 30 km (15 to 20 miles) travel a day.


Manatees are large, fully aquatic, mostly herbivorous marine mammals that belong to the family Trichechidae and the genus Trichechus. There are three accepted living species of Trichechidae: the Amazonian manatee, the West Indian manatee, and the West African manatee.

Manatees are sometimes called “sea cows” because of their gentle and slow-moving nature. They spend most of their time eating, resting, and traveling. Manatees are herbivores and eat aquatic plants, consuming floating, emergent, and submerged vegetation from freshwater, brackish, and saltwater environments. They are mammals and must surface to breathe air.

Manatees are usually seen alone, in pairs, or in small groups of a half dozen or fewer animals. They are graceful swimmers in coastal waters and rivers, powering themselves with their strong tails. Manatees are vulnerable to extinction due to loss of habitat and collisions with boats and ships.

To protect manatees, educational campaigns teach boaters to look for patterns caused by a manatee’s tail on the surface of the water so they’ll know if a manatee is nearby and to proceed cautiously through shallow waterways.

Red Panda

The red panda, also known as the lesser panda, is a small mammal native to the eastern Himalayas and southwestern China. It is slightly larger than a domestic cat with a bear-like body and thick russet fur. The red panda’s coat is mainly red or orange-brown with a black belly and legs, white-lined ears, a mostly white muzzle, and a ringed tail. Its head-to-body length is 51–63.5 cm (20.1–25.0 in) with a 28–48.5 cm (11.0–19.1 in) tail, and it weighs between 3.2 and 15 kg (7.1 and 33.1 lb).

Red pandas are very skillful and acrobatic animals that predominantly stay in trees. They use their long, bushy tails for balance and to cover themselves in winter, presumably for warmth. Red pandas are herbivores and eat aquatic plants, consuming floating, emergent, and submerged vegetation from freshwater, brackish, and saltwater environments.

Almost 50% of the red panda’s habitat is in the Eastern Himalayas, and they live in high-altitude, temperate forests with bamboo understories. The loss of nesting trees and bamboo is causing a decline in red panda populations across much of their range because their forest home is being cleared.

Red pandas are endangered, with a population of less than 10,000 individuals.

Manta Ray

Manta rays are large rays that belong to the genus Mobula and are classified among the Myliobatiformes (stingrays and relatives) and are placed in the family Myliobatidae (eagle rays) . The larger species, M. birostris, reaches 7 m (23 ft) in width, while the smaller, M. alfredi, reaches 5.5 m (18 ft) .

Manta rays have broad heads, triangular pectoral fins, and horn-shaped cephalic fins located on both sides of their mouths. They have horizontally flattened bodies with eyes on the sides of their heads, and gill slits on their ventral surfaces.

Manta rays are filter feeders and eat large quantities of zooplankton. They are highly intelligent and highly threatened, and the largest rays in the world.

Manta rays live in tropical, subtropical, and temperate ocean waters across the globe. For decades, scientists thought there was just one species of manta ray, but in 2008, researchers discovered that there are actually two distinct species: the reef manta ray and the giant oceanic manta ray.

The giant manta ray is the world’s largest ray with a wingspan of up to 30 feet.


Opossums are marsupials that are native to the Americas and are the largest order of marsupials in the Western Hemisphere, comprising 93 species in 18 genera. The most notable species is the Virginia opossum or common opossum, which is the only marsupial found in the United States and Canada.

Opossums are scavengers and often visit human homes or settlements to raid garbage cans, dumpsters, and other containers. They are attracted to carrion and are known for “playing possum” when threatened, which involves falling unconscious and exuding a smell like rotting meat.

Opossums are solitary, nocturnal animals about the size of a domestic cat and are successful opportunists. They have a triangular head, a long pointed nose, and grayish fur everywhere but on their ears, feet, and tail.

Opossums have opposable hallux, which are clawless big toes that work like thumbs and help them grab branches when they climb. A female opossum gives birth to helpless young as tiny as honeybees, and babies immediately crawl into the mother’s pouch, where they continue to develop.

Opossums may give birth to as many as 20 babies in a litter, but fewer than half of them survive.


The aye-aye is a nocturnal, arboreal lemur that is native to Madagascar. It is the world’s largest nocturnal primate and is currently classified as Endangered by the IUCN. The aye-aye is the only extant member of the genus Daubentonia and family Daubentoniidae. The aye-aye has rodent-like teeth that perpetually grow and a special thin middle finger.

The aye-aye is an omnivorous animal that feeds on both other animals and plant matter, moving about high up in the trees and under the cover of night. Males have huge home ranges, between 250 to 500 acres, while the home ranges of females are much smaller, usually between 75 to 130 acres.

Aye-ayes are solitary foragers who spend up to 80% of the night feeding and traveling through the forest canopy. They build their nests high in the trees and will rarely sleep in the same one two nights in a row. The aye-aye is often viewed as a harbinger of evil and death and killed on sight.

The aye-aye is thought to be one of the creepiest animals in the world with its name possibly believed to have come from the cry of alarm when a person spotted one.

Basking Shark

The basking shark is the second-largest living shark and fish, after the whale shark, and one of three plankton-eating shark species, along with the whale shark and megamouth shark. It is a slow-moving filter feeder, and its common name derives from its habit of feeding at the surface, appearing to be basking in the warmer water there.

The basking shark has anatomical adaptations for filter-feeding, such as a greatly enlarged mouth and highly developed gill rakers. Its snout is conical, and the gill slits extend around the top and bottom of its head. The basking shark is a coastal-pelagic shark found worldwide in boreal to warm-temperate waters, living around the continental shelf and occasionally entering brackish waters. It is often seen close to land, including in bays with narrow openings.

The basking shark is typically seen swimming slowly at the surface, mouth agape in open water near shore. It is one of only three filter-feeding shark species, eating tiny organisms called zooplankton.

The basking shark is harmless to humans and is often seen lying near the surface of the water with its dorsal and caudal fins exposed or with its belly up.

Goliath Birdeater

The Goliath Birdeater is a species of tarantula that belongs to the Theraphosidae family and is found in northern South America. It is the largest spider in the world by mass and body length, and second to the giant huntsman spider by leg span.

Despite its name, the Goliath Birdeater only rarely preys on birds; in the wild, its diet consists primarily of other large arthropods, worms, and amphibians. However, because of its size and opportunistic predatory behavior, this species commonly kills and consumes a variety of insects and small terrestrial vertebrates.

The Goliath Birdeater is native to the upland rainforest regions of Northern South America, including Suriname, Guyana, French Guiana, northern Brazil, eastern Colombia, and southern Venezuela.

Most noticeable in the Amazon rainforest, the spider is terrestrial, living in deep burrows, and is found commonly in marshy or swampy areas. The Goliath Birdeater is an edible spider and is part of the local cuisine in northeastern South America, prepared by singeing off the urticating hairs and roasting it.
