The American Eel lives in the far-flung corners of the North Atlantic. It has a snakelike body and can grow up to five feet, though most individuals measure only two to three feet.
Its skin ranges from yellow to green-brown, and it has a lighter belly, camouflaging it in riverbeds and coastal waters.
These types of eels are both freshwater and saltwater eels. They spend most of their lives in freshwater or brackish environments. However, during the breeding season, they migrate to the ocean.
Additionally, these true eels eat various prey, such as insects, crustaceans, and fish. At night, the American eel emerges from the sand to hunt. They also don’t hesitate to step onto land for food.
The European Eel can grow up to 5 feet long and camouflage itself in its environment. Moreover, they are nocturnal hunters that feed on insects, crustaceans, mollusks, and other small aquatic animals.
Additionally, European Eels are catadromous; they spend most of their lives in freshwater or brackish waters and travel to the Sargasso Sea to breed1.
They turn from larvae to glass eels during their journey, then to yellow and silver eels. These types of eels can also breathe through their skin, enabling them to survive short periods of drought.
The Japanese Eel lives off the coast of Japan, Korea, Vietnam, and the northern regions of the South China Sea. They are olive green, tranquil brown, white, or soft yellow. Moreover, they have small heads with large eyes that help them see in the dark.
The Japanese Eel migrates most of its time in freshwater or brackish waters. During the breeding season, they migrate into the ocean, swimming hundreds, or even thousands, of miles to reach spawning grounds in the far West of the North Pacific Ocean.
Part of the eel life cycle is the development of leptocephali, offspring that rely on ocean currents to guide them back to their freshwater habitats for several months3.
The mottled eel (Anguilla bengalensis), also known as the African mottled eel, the Indian longfin eel, the Indian mottled eel, the long-finned eel or the river eel is a demersal, catadromous eel in the family Anguillidae. It was described by John McClelland in 1844. It is a tropical, freshwater eel which is known from East Africa, Bangladesh, Andaman Islands, Mozambique, Malawi, Sri Lanka, Sumatra, and Indonesia and recently from Madagascar. The eels spend most of their lives in freshwater at a depth range of 3–10 metres, but migrate to the Indian Ocean to breed. Males can reach a maximum total length of 121 centimetres and a maximum weight of 7,000 grams. The eels feed primarily off of benthic crustaceans, mollusks, finfish and worms.
The Indonesian Shortfin Eel is a deep-brown to light-yellow eel that inhabits the Indian Ocean, Western Pacific Ocean, and Indonesian waters. It is a unique subspecies of the Shortfin Eel, characterized by its shorter dorsal fin beyond the pectoral fins. This catadromous eel lives in freshwater rivers and streams.
During the breeding season, these eels swim against the current and return to the ocean. Moreover, the Indonesian Shortfin Eel embarks on land excursions, using its slender body and sharp pectoral fins to explore new territories. They undertake these journeys at night when they emerge from their burrows and crevices.
Scanning their surroundings for prey, they mainly feed on small fish, crustaceans, and other invertebrates.
The African longfin eel[3] (Anguilla mossambica), also known simply as the longfin eel, is an eel in the family Anguillidae.[4] It was described by Wilhelm Peters in 1852, originally under the genus Muraena.[5] It is a tropical eel known from freshwaters in southern Kenya, Cape Agulhas, Madagascar, and New Caledonia. The eels spend most of their lives in freshwaters far inland, but migrate to the Western Indian Ocean to breed. Males can reach a maximum total length of 150 centimetres; females can reach a maximum standard length of 120 centimetres and a maximum weight of 5,000 grams. The eels can live for about 20 years.[4] Juveniles and adults are known to feed off of carcasses, crabs, and bony fish.[6]
The Zebra Moray Eel has a body pattern of alternating black and white stripes. It commonly lives in the coral reefs of the Indo-Pacific region, including the Red Sea, Hawaii, and the eastern coast of Africa. The eel's teeth are shaped like molars, crushing crustaceans such as shrimp, crabs, and mollusks before eating them.
Despite its unique appearance and eating habits, this type of eel is peaceful. When approached by divers or snorkelers, it retreats to rocky shelters.
The freshwater habitats of New Zealand are home to the New Zealand Longfin Eel. These eels can grow up to 6.6 feet long, with females reaching this maximum size. Hence, the New Zealand Longfin Eel is one of the world’s largest eel species.
These eels are olive green to brown. Their long dorsal fins are notable features; they undulate gracefully, helping them move quietly during nocturnal hunts. Despite their size, they are shy creatures.
During the day, they hide in shadowy locations, such as submerged logs or unseen crevices. Their keen sense of smell helps them find prey, primarily invertebrates, small mammals, and other fish.
Moreover, these eels can live for over a century but only breed once. During the breeding season, they embark on an epic journey from their freshwater homes to their spawning grounds in the deep Pacific Ocean near Tonga. After mating, the eels die. Then, thousands of minute larvae return to New Zealand, guided by the waves.
The speckled longfin eel, Australian long-finned eel or marbled eel (Anguilla reinhardtii) is one of 15 species of eel in the family Anguillidae. It has a long snake-like cylindrical body with its dorsal, tail and anal fins joined to form one long fin. The dorsal fin also often extends farther than the anal fin. It usually has a brownish green or olive green back and sides with small darker spots or blotches all over its body. Its underside is paler.[2] It has a small gill opening on each side of its wide head, with thick lips. It is Australia's largest freshwater eel, and the female usually grows much larger than the male.[2][3] It is also known as the spotted eel.
The Southern Shortfin Eel typically inhabits cooler freshwater areas in Australia, New Zealand, and Tasmania. This species is dark brown and olive green, with a lighter underbelly and a shorter dorsal fin. Due to their snake-like locomotion, they can briefly go on land.
The Southern Shortfin Eel also starts life in the deep Coral Sea, turning from larvae into transparent glass eels. Braving numerous challenges, these eels journey from their birthplace to freshwater habitats. Female eels are larger than males, growing up to 3.3 feet long.
These types of eels prefer to stay hidden during the day under rocks and vegetation. They are active at night, feeding on fish, crustaceans, insects, and worms.
The purple spaghetti-eel[2] (Moringua raitaborua) is an eel in the family Moringuidae (spaghetti/worm eels).[3] It was described by Francis Buchanan-Hamilton in 1822, originally under the genus Muraena.[4] It is a tropical eel known from India, Bangladesh, Nepal, Indonesia, and the Philippines. It inhabits rivers and estuaries (including ones in West Bengal, linked to the Ganges River), and has adapted to rapid and wide changes in salinity, pH, and osmoregulatory and hypoxic conditions.[5] Males can reach a maximum standard length of 44 cm.

Pike conger eels can live in fresh and saltwater environments, although they typically prefer saltwater. These eels can grow from two to eight feet long and survive depths of up to 2624.67 ft.
Approximately fifteen different species of pike conger eels live around the world.
Sawtooth eels are pelagic fish living in the dark depths of the ocean. Their name comes from their inward-facing saw-like teeth. This type of eel comprises around eleven species; most sawtooth eels have a maximum size of 24 to 28 in.
Growing up to 5 feet, this long, slender eel moves quickly through the rocky reef environment. The Mediterranean Moray Eel ranges from dark brown to soft grey, with a yellowish underbelly. It doesn't have pectoral fins.
This eel feeds on fish, squids, and octopuses. However, it's far from the top of the food chain as larger fish and marine mammals like seals and sea lions also prey on them.
Moreover, the Mediterranean Moray Eel forces water over its gills to breathe, requiring it to open and close its mouth rhythmically.
The Giant Moray Eel lives in the Indo-Pacific region's rocky seafloors and coral reefs. It is the world's largest moray eel, measuring 10 feet and weighing over 66 pounds. (The Slender Giant Moray Eel is longer.) Its brown skin has a unique dark spot pattern contrasting with the colorful reefs.
Moreover, this nocturnal eel hides in crevices and caves to avoid predators and rest for its nighttime hunts for fish, cephalopods, and crustaceans.
The Giant Moray Eel also forms alliances with coral groupers to hunt prey. It chases prey into open waters while the grouper takes advantage.
The California Moray Eel lives in the moonlit kelp forests of the eastern Pacific. Their color palette ranges from bronze to olive green and can grow up to 60 in long, although most average around 24 in. Despite their size, they are shy and spend their days hidden in rocky alcoves, away from other marine life.
At nightfall, the California Moray Eel becomes active and relies on its sense of smell to locate small fish or various invertebrates. It creates a cloud of slime to trap and paralyze its victim against the reef or kelp.
Additionally, the eel starts life as a female and becomes a male as it matures through a phenomenon called protogyny.
The California Moray is a primarily solitary species that mainly interacts with others during mating.
The Longfin African conger lives in the Indo-Pacific oceans, from the Red Sea and East Africa to the Marquesas and Easter Islands. They can survive depths of 262 feet, growing up to 4.3 feet long.
This type of eel feeds on small fish and crustaceans. It has an elongated body and fin extending from just behind the head to the tip of the tail, earning it the name 'Longfin.'
The Snowflake Moray Eel has a distinctive pattern of black splotches resembling snowflakes. It is a relatively small eel, typically up to 24 inches long. They live in the tropical Indo-Pacific region, among coral reefs and rock formations in warm summer waters.
The nocturnal Snowflake Moray Eel spends the day in reef crevices to avoid the sun. It is skilled enough to navigate its underwater labyrinth and hunt for food at night. Moreover, its long, flexible body allows it to probe into narrow corners and crevices, looking for small fish and crustaceans.
The Snowflake Moray Eel is peaceful when not on the hunt, attracting aquarium owners worldwide.
The Green Moray Eel inhabits the deep, shadowy waters of the western Atlantic Ocean. Green Moray Eels can grow up to 7.2 feet long and weigh approximately 64 lbs.
Despite its name, this species is not green, but its natural color is soft brown with a layer of yellow mucus. When hit by light, this mucus gives the appearance of vibrant green.
These types of eels periodically open and close their mouths because their gills require a continuous flow of water for breathing. They eat mainly fish, squids, and crabs. Lastly, they hide in dark crevices of coral reefs or rocky underwater terrains during the day and come out at night to hunt.

Corn snakes' preferred diet consists primarily of small mammals, particularly rodents. In the wild, they commonly feed on mice, rats, and other small rodents suitable for their size. Studies on the feeding habits of corn snakes suggest that they play a crucial role in controlling rodent populations.
Corn snakes are opportunistic feeders, meaning they will eat a variety of prey when available. Apart from rodents, they may consume unguarded bird eggs, birds, reptiles, amphibians, and invertebrates.
The Corn Snake has a distinctive reddish-orange, brown, and gray pattern resembling kernels of Indian maize. Likewise, black-bordered red splotches on their back and sides contrast sharply against their vibrant colors.
These types of snakes are skilled climbers who often explore the treetops, though they prefer the ground as their natural habitat. They also help balance the ecosystem by controlling potential rodent problems.
Corn Snakes become less active during winter but do not enter a complete dormancy like certain snake species. Like most snake species, they emerge at night but can appear unexpectedly during the daytime if the temperature is cool enough.
The Eastern Diamondback Rattlesnake is a large venomous snake native to the southeastern region of the United States.
It can grow up to 8 feet long and has a unique zigzagging diamond pattern in bright yellows and earth tones on its back. This colorful pattern warns other animals of its lethal venom. Its dark skin allows it to blend in with fallen leaves and shadows.
The Eastern Diamondback lives in various habitats, from North Carolina to Louisiana, from pine-clad flatwoods coastal scrub habitats to barrier islands.
Despite their menacing appearance, they are not typically aggressive. Besides its prey, the Eastern Diamondback only attacks other animals when the snake feels threatened. Its venom paralyzes its victims and aids in digestion.
Before biting, the snake will shake its rattle, made from the same keratin found in hair and nails, to warn intruders.

Garter snakes live in North America. To spot this type of snake, look for the stripes along its body, resembling the garters used to hold up stockings.
Moreover, there are approximately 35 different species of garter snakes3, each with its distinct colors and patterns. No two garter snakes are exactly alike.
The harmless garter snakes are moderately sized, ranging from 23 to 30 inches. They live in various landscapes, such as woodlands, meadows, marshlands, and urban areas, where they feed on earthworms, slugs, frogs, fish, and small mammals.
While they pose no danger, a few species of garter snakes produce neurotoxin, which is exceptionally mild.
Unlike most snakes, garter snakes are active during the day and can withstand cold temperatures.
The King Snake lives in North America. Its distinct bands of red, white, and black help it blend in with the shadows and light of the forests and desert.
Surprisingly, the King Snake is not venomous. But, it should not be underestimated.
The King Snake feeds on other snakes; their immunity to venom allows them to eat rattlesnakes, copperheads, and cottonmouths. During feeding, it chokes the life out of its prey.
The Milk Snake is a brightly colored species in various landscapes across North and South America. Its distinctive red, white, and black bands often lead to confusion with the venomous Coral Snakes.
Unlike Coral Snakes, Milk Snakes are harmless snakes. These nonvenomous snakes have red and black bands.
The Milk Snake is nocturnal, tending to hide in burrows and shadows during the day. It emerges at night to hunt suffocating prey like rodents, birds, reptiles, and eggs.
This diverse diet, combined with the Milk Snake's adeptness at hiding, allows it to thrive in various environments, including dense forests, open fields, and arid deserts.
Milk Snakes can also vibrate their rattles when threatened. However, we must remember that these snakes are generally peaceful and prefer avoiding humans.
Belonging to the Elapidae family, the coral snake is known for its iconic red, yellow/white, and black banding pattern, which serves as a visual warning to potential predators about its deadly venom.
Coral snakes represent a significant collection of snake species split into two main groups: the Old World coral snakes, found primarily in Asia, and the New World coral snakes, found across the Americas.
In North America, coral snakes are known for their potent neurotoxic snake venom, which targets the nervous system and can result in severe symptoms if not treated promptly. Despite their small size, both the Eastern and Arizona coral snake species, two of the most commonly found coral snake species in America, carry a highly effective venom, yet are rarely a problem for humans, whom they tend to avoid.
Furthermore, these snakes exhibit a fascinating behavior known as "shy biting," where they often hold onto their prey after biting instead of striking and releasing.

The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the subfamily Crotalinae (pit vipers). What is commonly called a pit organ allows these animals to essentially "see" radiant heat at wavelengths between 5 and 30 μm. The more advanced infrared sense of pit vipers allows these animals to strike prey accurately even in the absence of light, and detect warm objects from several meters away. It was previously thought that the organs evolved primarily as prey detectors, but recent evidence suggests that it may also be used in thermoregulation and predator detection, making it a more general-purpose sensory organ than was supposed.
World Snake Day raises awareness about snakes' complex and essential function in nature. They are responsible for controlling rodent and pest populations, which helps prevent crop damage and the spread of diseases. Many snakes are also the food source of other snakes, mammals, and birds of prey.
Because of their role in maintaining ecological balance, the snakes' presence indicates a healthy environment. Even though snakes live almost anywhere, they face habitat loss. The driving forces are rapid urbanization, deforestation, and human encroachment. Additionally, fear and misconceptions about snakes contribute to unnecessary killings.
In addition to dispelling myths, World Snake Day also illuminates the global snakebite crisis, particularly in rural parts of Africa, Asia, and Latin America.
Limited access to antivenom treatments and medical facilities poses a serious public health issue. This day advocates for improved healthcare measures and raises awareness among communities near snake habitats.
