Animals Starting With J

Mammalian species like jackals, jackrabbits, jerboas, junglefowl, and the jaguar; avian species like jaegers, jays, and juncos; fish like the John Dory; and invertebrate species like Jerusalem crickets and jumping spiders are among those that begin with j.

Beginning with J, you’ll discover pictures and information on a variety of fascinating animals on this page.

Links to further information, pictures, and videos can be found below many of the animals you’ll find.

Individual species (the jaguar) and well-known groupings of species (jackals) are included in this list. Each of the separate species has its scientific name and conservation status.

Jaguar

The jaguar is a big cat species found in South, North, and Central America that is the biggest in the Americas and third biggest in the world (behind tigers and lions).

Jaguars are currently designated as an endangered species due to illegal trade, human conflict, and habitat destruction.

Jaguars are now essentially restricted to the Amazon basin and Pantanal wetlands, having formerly been found from south-western USA to central Argentina.

Their name comes from the indigenous term ‘yaguar,’ which means “he who kills with a single leap.” In the wild, jaguars can expect to live 12-15 years.

Jaguars have tan or orange fur with black markings and short legs, huge heads, and rounded ears.

Jabiru

The stork family, Ciconiidae, includes the jabiru, which is a large and striking-looking member. It can be found in Central America and north into Mexico, as well as South America from Columbia south to central Argentina. In the United States, it’s only seen on a regular basis.

The jabiru, like all storks, is a tall-legged, long-necked bird. The jabiru is South America’s tallest flying bird, although not the continent’s tallest bird; the rhea (which is flightless) is somewhat taller. Standing at up to 5 feet / 1.52 meters tall.

The body and wings of the jabiru are light gray in color. A bright red band runs down the base of its neck. The neck is black, as is the head and beak.

The jabiru waits for prey to approach within biting range by holding its massive beak in the water. The jabiru is an opportunistic feeder that eats small creatures, such as fish, tiny reptiles, mollusks, and insects. It eats them all.

Jacana

The tropical wetlands of the world are home to the jacana, a family of colorful and long-legged water birds. Eight species have been identified from the fossil record, with four more extinct species.

Waders, gulls, and auks are all members of the same order. The identification, behavior, and diet of this unique bird will all be discussed in this article.

Jackal

Jackals are a medium-sized breed of canines that are related to house dogs, wolves, coyotes, and foxes.

Jackals have a small face, a fluffy tail, nimble legs, and long, pointed ears that make them resemble a fox with a German shepherd.

In the wild, jackals have a lifespan of 8–9 years. They may live up to 16 years in captivity.

Birds, reptiles, other small creatures, insects, fruits, and plants are the primary foods of jackals.

Scavengers are also known to be active. Dawn, dusk, and nighttime are when jackals are most active. Side-striped jackals, on the other hand, are strictly nocturnal.

Jackals are physically suited for long distance running due to their united leg bones and huge feet, and can maintain speeds of 16 km/h.

While they may occasionally assemble in small packs (mostly to make hunting easier and take on huge prey like antelopes), jackals normally dwell in monogamous couples with their offspring.

Jacamar

The Galbulidae family includes eighteen different species of jacamar. They’re tiny, brightly-colored birds that live in Central and South America’s woods and forests.

The bills of Jacamars are long and slender, allowing them to capture their prey in mid-flight. Jacamars usually wait for prey to approach within range by sitting on a suitable perch.

The biggest jacamar species is the giant jacamar Jacamerops aureus, which grows to lengths of up to 30 cm/12 in. It can be found in Central and South America’s rainforests.

Jackrabbit

In just one jump, a black-tailed jackrabbit may cover ten feet of ground. In the south and western United States, as well as Mexico, a black-tailed jackrabbit is a hare.

The hare has grayish-brown fur on the majority of its body and white fur on its face, in addition to having a black tail. Grass, bark, cacti, and twigs are all eaten by this herbivore. This hare has a five to eight-year lifespan.

Jay

The crow family includes the Jays, which are a mid-sized bird. There are 35-40 jay species in Eurasia and North America that are typically colorful and noisy.

Jays are woodland creatures that prefer to stay hidden. Their screaming call will tell you that they are nearby, rather than seeing them. Jays construct cuplike nests in trees.

Other birds’ eggs, tiny animals, insects, seeds, and nuts are nearly all eaten by Jays.

They’re well-known for storing acorns throughout the winter, which they’ll consume. Jays play a crucial role in oak tree distribution as a result of their behavior. A jay may conceal up to 5,000 acorns in a season.

Jaeger

The skua family of birds, Stercorariidae, is known as jaeger in North America. The long-tailed jaeger, Arctic or parasitic jaeger, and pomarine jaeger are the three jaegers that exist. These birds are known as skuas outside of North America.

The Arctic breeds large seabirds known as jaegers. Kleptoparasitic behavior is well-known among jaegers. Rather of catching its own prey, a kleptoparasite steals it from other species. Other seabirds’ food is stolen by skuas.

The majority of a skua’s diet comes from food obtained from other birds, however they do catch their own food as well.

Skuas move from their feeding grounds in the South Pacific and Southern Oceans to their breeding grounds in the Arctic on a yearly basis.

Jackdaw

A clever and mischief-prone bird, a capable scavenger, and a devoted companion, the jackdaw is a unique creature.

The Eurasian jackdaw, which may be found from Western Europe to Central Asia, and the Daurian jackdaw, which resides in eastern Asia, are the two species that are generally recognized. They are highly intelligent and sociable, as members of the Corvid (crow) family.

They are one of the few animals in the world that uses tools. There are various fascinating facts about this clever bird, which is an essential part of symbolism in numerous human civilizations.

Jellyfish

Jellyfish are among the oldest creatures on Earth, dating back to the time of dinosaurs! Finding jellyfish fossils is difficult due to the fact that they don’t have bones.

Scientists may, however, discover proof that jellyfish have existed for almost 500 million years.

There are almost 10,000 species of jellyfish in the world’s oceans, which belongs to the Cnidaria family.

Jellyfish may be found in both chilly and mild seas. Some jellyfish have beautiful hues and may be bioluminescent (i.e., glow). They generate their own light.

Jellyfish aren’t actually fish, despite their name. They are invertebrates with no brain, heart, or eyes, and their tentacles are equipped with minute, stinging cells that they employ to paralyze and protect themselves. They may be referred to as “gelatinous zooplankton.”

Plankton are jellyfish. They are reliant on ocean currents since they are poor swimmers.

Jaguarundi

Throughout much of South America and Central America, the jaguarundi is a wild cat. In addition, Florida and other southern states in the United States are occasionally seen. It may be found in rainforests, savannas, and other environments.

The jaguarundi has short, rounded ears and rather small legs when compared to a domestic cat. Even if their siblings are the other color, individuals can be either golden-red or gray in the species’ coat.

Jackson’s Chameleon

The dwarf Jackson’s chameleon retains the three horns that are characteristic of the species, despite its tiny size.

The Jackson’s chameleon is mostly recognized for its three horns that adorn its face. It is also known as the Kikuyu three-horned chameleon.

It is one of the few reptiles that give birth to live offspring (albeit the hatchlings are kept in the female for many months). While it isn’t well-known for being the biggest or smallest of any species, it is notable. Many people choose to care for Jackson’s chameleon as a pet because of its bright green color, which is easy to spot.

Jerboa

The jumping rodents group includes Jerboas, which are small animals. They live in scorching and frigid deserts all over North Africa and Asia. Jerboas come in a variety of shapes and sizes.

Each species has a unique size and color. The fur color matches the surroundings to provide camouflage.

Their tails end with white tufts, while the fur is generally beige, brown, or yellow.

Long, silky, and soft fur coats their bodies. Mice are similar to Jerboas in appearance. Their eyes are huge, and they have whiskers, as well as ears that are modest or enormous depending on the environment.

Japanese Macaque

The Japanese macaque is a monkey that only lives in Japan and inhabits a variety of forest environments.

The Japanese macaque is the only primate (other than man) that may be found north or in colder climes, and it is known as the “snow monkey” since most of the time spent in its climes is spent under snow.

Due to their communal bathing in the park’s hot springs, Japanese macaques living in Jigokudani Monkey Park have become a tourist attraction.

Javan Rhinoceros

The Sunda rhinoceros (also known as the lesser one-horned rhinoceros) is a Southeast Asian species of rhino that was formerly referred to as the Javan rhino. The Indian rhinoceros, which only has one horn, is thought to be the most closely related to the Javan rhinoceros.

Just 72 Javan rhinos are thought to remain in the Indonesian national park of Ujung Kulon on Java’s westernmost tip as of 2019. Despite the fact that no poaching of the species has been documented in Ujung Kulon for more than 25 years, there is optimism for its survival.

Junglefowl

The native birds of South and Southeast Asia are junglefowls. Their progeny would eventually become domestic chickens.

Moist woods, scrub lands, mangroves, as well as tea and palm-oil plantations are all home to Junglefowls. They have a lifespan of up to 25 years.

Junglefowls are smaller and have a more vivid color than domestic chickens when compared to each other.

Males have brighter colors and are larger than females. Males have long, golden feathers on their backs and necks, with black tails that sparkle in the light with exquisite blue, green, and purple hues.

Japanese Squirrel

The Sciuridae family of squirrels includes the Japanese squirrel. On the Japanese islands of Honshū and Shikoku, it can be found in lowland to subalpine (below the tree line) pine forests. Until recently, the species was also found on Awaji Island.

On account of their arboreal (tree-dwelling) lifestyles, Japanese squirrels are one of around 100 species known as “tree squirrels.”

The squirrel family, Sciuridae, also includes ground squirrels and flying squirrels. Tree squirrels are frequently referred to as simply “squirrels.”

Jumping Spider

Jumping spiders, which belong to the biggest spider family, are diurnal and prefer to hunt in the day. They come in a rainbow of colors, which makes them stand out among arachnids, even the biggest of them, Hyllus giganteus.

The spider stalks and jumps on insect pests in the worst way possible, not just for their looks; it stalks them purposefully before delivering a deadly, venomous bite. Here are more facts about this fascinating little spider.

Javanese Cat

Long, athletic bodies characterize Javanese cats, who are medium-sized cats. They are not native to Java, despite their name. The Siamese-like group includes Javanese cats, which are bred in North America.

Javanese cats were developed to combine the characteristics of Siamese cats with a unique coat.

Balinese, Colorpoint Shorthair, Oriental Longhair, and Oriental Shorthair are among the cat breeds available via its line.

The Javanese cat is the ideal pet for persons who suffer from allergies due to its semi-long, soft, silky fur. There are 24 different hues available.

Jerusalem Cricket

Jerusalem crickets are large flightless insects that can be found in North America, and they are also known as “potato bugs.” Jerusalem crickets are frequently mistaken for spiders because of their large abdomens, lack of wings, and wide gait.

Ammopelmatus, which is found in the United States and Mexico, and Stenopelmatus, which is found in Central America, are the two genera that divide the 40-odd species of Jerusalem cricket.

Jerusalem crickets (family Gryllidae) are not true crickets, despite their name. They have the extended hind legs characteristic of insects in this category, and they are placed in the same sequence as crickets.

Jerusalem crickets have ferocious jaws that can cause a severe bite if wwhenpossessed.

Jonah Crab

The Jonah crab is a marine crab species that lives in the waters off the eastern coast of North America.

Its claws and legs, which have a lower cost than other kinds of crabs, are prized for their sweet and flavorful flesh.

It has yellow or light spots on its carapace and dark-tipped claws, which gives it a rough edge. In the Western Atlantic, this crab from the Northwest Atlantic is closely related to the European brown crab.

Jico deer mouse

The Jico deer mouse, a rodent indigenous to Mexico, is considered an endangered species.

It lives in subtropical and tropical wet lowlands and woods. Jico deer mice are just 40 grams in weight! Unfortunately, little information on this species is available.

John Dory

Off the coasts of Europe, Africa, Southeast Asia, Australia, and New Zealand are found the John Dory marine fish.

The John Dory has ten large spines on its dorsal fin. The fish’s body is spherical and extremely thin, making it difficult to see from the front.

The John Dory has a large eye-like marking on each side of its pale orange body. To startling potential predators or perplex prey, the fish will turn and flash its eye-marking.
