Jaguars are beautiful creatures that are native to the warm climate in Central America. They can live up to 20 years in the wild and are extremely recognizable as they have striking black and golden dots all over their fur.

They can weigh up to 200 pounds when they are fully grown adults. 

As born hunters, jaguars are carnivores, which means that they eat meat. They hunt their prey in their natural habitat, the rainforest, where they come across monkeys, birds, foxes, and snakes to eat.

They stalk their prey by either hiding in thick leaves or climbing trees before they pounce on their food source. 


Jackrabbits are often mistaken for being the same kind of rabbits that people keep as pets, but they are more similar to hares. They are larger than rabbits and they have long ears that stand up straight.

They are traditionally found in North America and they make their homes in deserts, meadows, or grasslands. 

They are nocturnal animals, meaning that they only come out at night. In the nighttime, they feast on branches, leaves, and bark that they find in their habitat.

They can survive for up to 5 years in the forest as there is plenty for them to eat, and they can weigh up to 4kg. They can reach up to 60cm long and are very quick movers. 


Jellyfish live in fresh water and there are lots of different types of this species. The largest type is called a Lion’s Mane jellyfish, and it can grow up to 1 meter long.

This species can live for up to 12 months, but others can live for a shorter amount of time. They have no bones, heart, eyes, or brain.

Jellyfish are fascinating creatures as some types can clone themselves and glow in the dark. They have poisonous tentacles that they use in self-defense that help to protect them from predators and to catch prey for themselves to eat.

Their mouths are found at the center of their heads, not at the front where you would think!


Jackals are not very common animals, but they are a type of dog that lives in Africa and Europe. They live in the desert or in the savanna where they have access to their food sources.

It is easy for jackals to catch their prey as they have incredibly sharp teeth and claws that attack their prey. They also have very strong legs that help them to run far and fast to chase their prey.

Jackals can weigh up to 13kg and grow to 9cm long, so they are large enough to spot, but they often blend into their surroundings due to their sandy-colored coats.

Jumping Spider

Jumping spiders are often found to be living in the forest, mountains, or the desert. They can grow up to 20mm in size, so they can be quite difficult to spot, but they have an exceptionally strong body that is covered in thick hair.

They are usually black and golden-colored and have 4 big eyes at the front of their heads. 

When jumping spiders catch their prey, they do not use webs to trap them. Instead, they use their ability to jump up to 50 times their body.

They eat insects like cockroaches, crickets, and flies, where they pounce on them to immobilize them. They are fast on the ground and can live up to 12 years. 


Jerboas are also known as desert rats and they are found to be living in warm climates, most notably in Asia and Africa.

Unlike other types of rats, Jerboas only have two legs, which are long and allow them to jump up to 3 meters.

Their bodies can grow up to 10cm long and their tails can grow up to 20cm long. 

When Jerboas are hunting their prey, they prefer to do it at night as they are nocturnal animals and it is cooler for them to source food.

They hunt for small insects, but they also feast upon plants and seeds to stay alive. They do not drink water, which is why they thrive so well in the desert climate!
