The World of ‘S’ Animals

1. Snake 


Snakes are elongated, legless, carnivorous reptiles distinguished from legless lizards by their lack of eyelids and external ears. They are found in a wide range of habitats worldwide, with around 3,600 known species.

Interesting Facts:

  • Snakes have a unique anatomy that allows them to swallow and digest large prey.
  • They have flexible jaws, which allow them to eat prey bigger than their head!
  • Snakes are found on every continent except Antarctica.
  • Some species of snakes have a venomous bite, which they use to hunt and defend themselves.
  • Snakes have internal ears but not external ones.

2. Shark

Brief Description

Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven-gill slits on the sides of the head, and pectoral fins that are not fused to the head.

They are known for their cylindrical shape and tapered edges, which allow them to sail smoothly through deep waters.

Sharks are usually 5.8 to 7 meters long and weigh up to 5500 pounds. They are naturally colored to camouflage and blend with their surroundings.

Interesting Facts

  • Sharks have no bones. Their body is primarily made of cartilage, the same material from which the human nose and ears are made.
  • They have pretty good eyesight, meaning they can see clearly in dim-lighted areas.
  • The skin of sharks often feels like sandpaper due to small teeth-like structures.
  • Sharks can become immobile when flipped upside down, known as tonic immobility.
  • Sharks are ancient fish, and scientists believe these fishes have been around more than 450 million years ago.
  • One species of shark — the epaulette shark — has evolved the ability to walk on land over small distances!
  • Sharks have long been thought to have a sixth sense, known as electroreception, which allows them to detect electric fields and temperature shifts in the ocean.

3. Skunk


Skunks are omnivorous animals known for their ability to spray a strong, unpleasant scent to deter predators.

They have a distinctive black and white coat, which warns other animals to stay away. Skunks are found in Canada, the United States, Mexico, and South America.

They are generally solitary creatures, although they may group in colder climates for warmth. Skunks can range from 8 to 19 inches in length and can weigh between 6 to 14 pounds.

Interesting Facts

  • A skunk’s spray can be detected at up to 1.5 miles.
  • Skunks are not affected by snake venom.
  • They can have between 2 to 10 babies in a litter.
  • Skunks are known to carry rabies and can pass it to other animals or even a family pet.
  • The lifespan of a skunk can be up to 7 years, but the average age is 3.

4. Salamander


Salamanders are amphibians that are found all over the world, including Europe, Asia, North America, and South America.

They are nocturnal carnivores active at night, with some species burrowing in the mud to make their homes under rocks near bodies of water.

Salamanders can range in size from less than an inch to as long as 6 feet, with the largest being the Chinese giant salamander, which can grow to 130 pounds.

The average lifespan of a salamander is around ten years, but this can vary according to species.

Interesting Facts

  • Salamanders must keep their skin wet and cool to survive.
  • They can’t hear sound but can feel vibrations in the ground to detect movements around them.
  • A salamander can regrow a tail it has lost in an attack.
  • Some salamanders live under rocks, while others live in trees.
  • Depending on its species, a salamander can lay up to 450 eggs at one time.

5. Squirrel


Squirrels are a family of small or medium-sized rodents. They are native to Africa, Eurasia, and the Americas and have been introduced to Australia.

They are known for their bushy tails and the ability to climb trees. Squirrels can range from 5 inches to 3 feet long, depending on the species.

They are generally very active during the day and can be seen foraging for food, primarily nuts and seeds.

Interesting Facts

  • More than 200 squirrel species live worldwide, with the notable exception of Australia.
  • The smallest squirrel is the African pygmy squirrel which is only five inches long from nose to tail. On the other hand, the Indian giant squirrel can reach up to three feet long.
  • Like other rodents, squirrels have four front teeth that never stop growing, so they don’t wear down from the constant gnawing.
  • Tree squirrels are the most commonly recognized, often seen gracefully scampering and leaping from branch to branch.
  • Other species are ground squirrels that live in burrow or tunnel systems, where some hibernate during winter.

6. Squid


Squids are cephalopods, a type of mollusk, and are closely related to octopuses. They are known for their streamlined bodies and two long tentacles.

Squids are strong swimmers, and certain species can ‘fly’ for short distances out of the water. They can be found in both saltwater and freshwater and are known to inhabit every ocean in the world.

Squids vary, with the smallest species measuring about 1 inch long and the largest, the colossal squid, reaching lengths of up to 46 feet.

Interesting Facts

  • Squids have three hearts. Two pump blood to the gills, while the third pumps it to the rest of the body.
  • Their blood is blue. This is because it is copper-based, turning blue when it oxidizes.
  • Squids are known for their speed. They are among the fastest invertebrates in the world.
  • They have complex brain structures, excellent eyesight, and are thought to be quite intelligent.
  • Some squid species can change color. They use this ability for communication and camouflage.

7. Seahorse


Seahorses are fish known for their unique upright swimming and a horse-like head. They are found in coastal waters around the globe, with more than 45 species identified.

Seahorses have a unique body structure with flesh-covered bony plates instead of scales.

Their eyes work independently of each other, and they use prehensile tails to grip holdfasts on the seafloor to avoid being swept away by currents.

Their colors vary and can change to offer camouflage or to signal a foe or potential mate.

Interesting Facts

  • Seahorses are among the only animal species on Earth where the male bears the unborn young.
  • Most seahorses are monogamous and mate for life.
  • Seahorses have a unique feeding mechanism; they suck their food through their long snouts.
  • They are poor swimmers and often attach themselves to seagrass or other underwater plants.
  • Seahorses are under threat due to habitat loss and are often used in traditional medicine or sold as aquarium pets.

8. Saanen Goat


The Saanen Goat, also known as the “queen of the dairy goats,” is a charming white goat renowned for its high milk production and sweet temperament.

Originating from a region in Switzerland known for its dairy production, the Saanen Goat is one of the most popular goat breeds. It thrives in various climates but has a preference for cooler weather.

The Saanen Goat is admired for its looks, robustness, and resistance to diseases.

Interesting Facts

  • A Saanen Goat can produce up to three gallons of milk a day.
  • Saanen Goats are excellent diggers that can dig out of a fenced area.
  • Despite being the largest dairy goat breed, Saanen Goats are docile and easy to handle.
  • Saanen Goats are friendly with most animals and make excellent pack goats.
  • They are resistant to diseases and have tough hooves, making them adaptable to various climates.

9. Sloth


Sloths are slow-moving creatures that spend their lives in tree canopies, munching on leaves and napping.

They move through the canopy at about 40 yards per day. Sloths have a low metabolic rate and sleep 15 to 20 hours daily.

Interestingly, these long-armed animals are excellent swimmers and occasionally drop from their treetop perches into the water for a paddle.

There are two different types of sloths, two-toed and three-toed, and six species: Pygmy three-toed sloth, Maned sloth, Pale-throated sloth, Brown-throated sloth, Linnaeus’s two-toed sloth, and Hoffman’s two-toed sloth. The pygmy sloth is critically endangered, and the maned sloth is vulnerable.

Interesting Facts

  • Habitat: Sloths are an integral part of tropical rainforest ecosystems. Among the most common mid-sized mammals in Central and South American rainforests is the brown-throated sloth.
  • Threats: The health of sloth populations is wholly dependent on the health of tropical rain forests. But tropical rain forests are at risk of deforestation. Without an abundance of trees, sloths will lose their shelter and food source. When sloths come to the forest floor—which they do once a week to relieve themselves—they are more exposed to predators and can do little to fend off.
  • Conservation Efforts: WWF works with communities, governments, and companies to encourage sustainable forestry. WWF created the Global Forest & Trade Network to create a market for environmentally responsible forest products. The network works at national and regional levels to expand the area of forests under responsible management. And since 2003, WWF has been working with the Brazilian government on the Amazon Region Protected Areas initiative (ARPA) to protect the rain forest. ARPA has become the largest conservation project in the world.

10. Salmon


Salmon are large fish native to the rivers on both sides of the North Atlantic and the Pacific Ocean.

There are six species of Pacific salmon and one Atlantic species. The adult Atlantic salmon averages about 10 pounds in weight, while the king salmon averages about 23 pounds, though individuals of 50–80 pounds are not uncommon.

Salmon are silvery-sided fishes in the ocean, but during the breeding season, a change in coloration occurs that varies from one species to another. The males generally develop hooked jaws.

Interesting Facts

  • Life Cycle: Pacific salmon live mostly in the ocean, but as adults, they return to the stream where they hatched to spawn. They use their olfactory senses (their sense of smell) to find their spawning grounds in their home river, and at least one species, the sockeye salmon, can also sense differences in Earth’s magnetic field to navigate back to its home stream from the open ocean. The female digs a pit in the stream gravel into which she and a male spawn simultaneously, and she then covers up the eggs with gravel. Adult Pacific salmon die soon after spawning, but many Atlantic salmon return to the sea and after one or two years in open waters may spawn again, some up to three or four times.
  • Migration: The migrating salmon, impelled by instinct, fight rapids and leap high falls until they reach their spawning grounds. Even landlocked salmon, which mature in deep lakes, ascend tributary streams to spawn. The spawning grounds may be close to the sea, but the king and chum salmon swim more than 2,000 miles up the Yukon River to spawn in its headwaters.
  • Commercial and Recreational Importance: Although fished commercially in certain areas, Atlantic salmon are valued chiefly as sport fish. They are farmed in fish pens in many parts of the world. The king and coho salmon are prized sport fish in the larger rivers of the Pacific coast. The commercial fishery of Pacific salmon nets millions of pounds annually, of which nearly half is pink salmon, one-third is chum salmon, and most of the remainder is sockeye.

11. Scorpion


Scorpions have elongated arachnids characterized by a segmented curved tail tipped with a venomous stinger at the rear of the body and a pair of grasping pincers at the front.

They are most common and diverse in deserts but inhabit many other environments. Scorpions are primarily nocturnal and have a reputation as evildoers in fables and legends.

They are relatively large among terrestrial arthropods, with an average size of about 6 cm (2.5 inches). Approximately 1,500 species of scorpions exist, but only 30 or 40 have strong enough poison to kill a person.

Interesting Facts:

  • Survivors of Evolution: Scorpions have been around for hundreds of millions of years, making them one of history’s great survivors. They are hardy, adaptable arthropods that have survived in various harsh locales.
  • Dietary Adaptability: Scorpions typically eat insects, but their diet can be extremely variable, which is another key to their survival in so many harsh locales.
  • Venomous Creatures: There are almost 2,000 scorpion species, but only 30 or 40 have strong enough poison to kill a person. The many types of venom are effectively tailored to their users’ lifestyles and are highly selected for effectiveness against that species’ chosen prey.
  • Reproduction and Life Cycle: Scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female’s body, where the embryos are nourished in utero for several months to a year. The birth process itself may last from several hours to several days.
  • Feeding Habits: Scorpions are opportunistic predators that eat any small animal they can capture. They lack conventional jaws, and their feeding habits are unusual. They chew the prey as quantities of digestive fluids pour over the midgut. The victim’s soft parts are broken down, liquefied, and sucked into the scorpion’s stomach by a pumping action. Eating is a slow process, often taking many hours.

12. Sea Otter


Sea Otters (Enhydra lutris), also known as great sea otters, are completely marine otter species found along the coasts of the Pacific Ocean in North America and Asia.

They are the largest otter species, reaching 100–160 cm (40–65 inches) long and weighing 16–40 kg (35–90 pounds) when fully grown. Sea otters have webbed feet, water-repellent fur to keep them dry and warm, and nostrils and ears that close in the water.

They spend most of their time in the water, often floating at its surface, lying on their backs in a posture of serene repose.

Interesting Facts

  • Tool Use: Sea otters are a few mammal species that use tools. They often use rocks to break open crabs and other shellfish, whereas sea urchins are crushed with their forefeet and teeth.
  • Kelp Forest Guardians: Sea otters play a crucial role in maintaining the health of kelp forests. By consuming herbivorous urchins, they enable kelp forests and the fish associated with them to flourish.
  • Social Creatures: Sea otters gather in groups of up to 1,000 individuals, grasping one another’s forefeet to create large rafts or pods.
  • Endangered Species: Although the sea otter had been hunted almost to extinction for its fur by 1910, it has made a modest recovery during the 20th century due to conservation efforts. However, population declines since the 1980s due to pollution from oil spills, conflicts with fisheries, predation by sharks and killer whales, and disease prompted the International Union for Conservation of Nature and Natural Resources to reclassify the sea otter as an endangered species in 2000.
  • Unique Reproduction: Female sea otters give birth in water to only one young at a time, and the young remain dependent on the mother until six to eight months of age.

13. Sea Turtle


Sea turtles are marine reptiles that belong to two main families: Dermochelyidae, which includes the leatherback sea turtles, and Cheloniidae, which includes green turtles, flatback sea turtles, loggerhead sea turtles, hawksbills, and ridleys.

They are highly aquatic, and most species only appear on coastal beaches for egg-laying. Adult sea turtles are mainly found in tropical and subtropical seas, but the juveniles of both families occur naturally in more temperate waters.

The leatherback is the largest sea turtle, weighing up to 2,000 pounds. It’s also the only sea turtle that doesn’t have a hard, bony shell. Its carapace is somewhat flexible and almost rubbery to the touch.

Interesting Facts

  • Long-Distance Travelers: Sea turtles migrate incredibly long between feeding and breeding areas. The leatherback travels an average of 3,700 miles each way.
  • Dietary Habits: With some exceptions, most sea turtles are carnivorous and prefer warm, coastal marine environments. The leatherback sea turtle inhabits pelagic (open ocean) environments and follows the blooms of its jellyfish prey, moving widely throughout the oceans.
  • Reproduction: All sea turtles are egg layers, and females must come ashore to bury their eggs in sandy environments. Females nest only every third or fourth year; however, they often nest multiple times during a nesting season. While most species usually have two to four egg-laying events per nesting season, the loggerhead has up to seven.
  • Conservation Status: Most species of sea turtles are threatened or endangered. They are typically slow to mature, long-lived, and migratory; before reaching sexual maturity, many are intentionally or accidentally captured in coastal fisheries and killed. The minimum time from hatching to first reproduction appears to be about 10 to 15 years, a characteristic shared by the largest species, D. coriacea, and the smallest species, L. kempii and L. olivacea. Others, such as Chelonia mydas, require over 20 years to reach sexual maturity and reproduce for the first time.

14. Stork


Storks are long-necked large birds that belong to the family Ciconiidae, related to the herons, flamingos, and ibises.

They range from about 60 cm to over 150 cm (2 to 5 feet) in height. All or part of the head and upper neck may be bare of feathers and brightly colored.

Storks are voiceless or nearly so, for lack of a fully developed syrinx (vocal organ), but some clatter their bills loudly when excited.

They fly, alternately flapping and soaring, with necks outstretched and their legs trailing. Storks occur mainly in Africa, Asia, and Europe. One species, the black-necked stork, also occurs in Australia.

Interesting Facts

  • Variety of Species: About 20 species of storks vary greatly in appearance. For example, the saddle-billed stork of tropical Africa is more than 120 cm (4 feet) tall, with exceptionally long and thin legs and necks. Its slightly upturned bill is red, crossed by a broad black band surmounted by a small yellow plate in front of the eyes.
  • Feeding Habits: Most storks eat small animals caught in shallow water and fields. Some feed primarily on carrion, like the marabou stork of Africa and the adjutant stork of India. The open-billed storks of Africa and Asia have a gap in their bill that is likely an adaptation for holding snails, their primary food source.
  • Breeding Season: Most storks are found in flocks except during the breeding season when they pair off. The nest, a large twig platform built by both sexes, is constructed in trees, on rock ledges, or, in the case of the white stork, on rooftops and chimneys, often in colonial groupings. Both parents and hatch incubate three to six chalky-white eggs in about five weeks.

15. Swan


Swans are the largest waterfowl species of the subfamily Anserinae, family Anatidae.

They are gracefully long-necked, heavy-bodied, big-footed birds that glide majestically when swimming and fly with slow wingbeats and with necks outstretched.

Swans feed by dabbling (not diving) in shallows for aquatic plants. Male swans, called cobs, and females, called pens, look alike. Swans are sociable except in breeding season. They mate for life.

Interesting Facts

  • Variety of Species: There are about seven or eight species of swans—some of them probably races of a species. Five are all-white, black-legged birds of the Northern Hemisphere: the mute swan, the trumpeter swan, the whooper swan, Bewick’s swan, and the whistling swan. The Southern Hemisphere has the black swan (Australia) and two pink-legged forms (South America): the black-necked swan and the coscoroba.
  • Breeding Season: Courtship involves mutual bill dipping or head-to-head posturing. The pen incubates, on average, a half-dozen pale unmarked eggs on a heap of vegetation while the cob keeps close guard; in some species, he takes his turn at brooding. After repulsing an enemy, swans utter a triumph note, as geese do. The young, called cygnets, emerge short-necked and thickly downed; though capable of running and swimming a few hours after hatching, they are carefully tended for several months; in some species, they may ride about on their mother’s back.
  • Lifespan: Swans mature in the third or fourth year and live perhaps 20 years in the wild and 50 years or more in captivity.
