  1. Jackal

    • Jackals are a type of canine, animals that are related to dogs, coyotes, foxes and wolves. They look like a cross between a German shepherd and a fox. They have the fox’s small face, delicate legs and fluffy tail, with the German shepherd’s long, alert ears. There are three species of jackal. Jackals are often both diurnal and nocturnal. This means that they are active during dawn, dusk and night. As omnivores, jackals like to eat both meat and vegetation. Their diet consists of leftovers from other animals’ kills, ground-dwelling birds, reptiles, antelopes, fruits, insects, berries and grass. They’re not picky, though! Each jackal family has their own yipping sound that only members of their own family respond to. 
  2. Jaguar

    • One of the big cats, jaguar’s are solitary animals, usually hunting at night, they often drag their food up trees for safe keeping, they love to swim and roam the rainforests of Central and South America. The jaguar is the 3rd largest of the big cats after the tiger and the lion and it is the largest of all the big cats in the Americas. With its spotted coat the jaguar most closely resembles the leopard which is found in Asia and Africa, however, the jaguar is larger and has a stockier build than the leopard, it also has less but bigger rosettes (spots) with small dots in the middle. Like the tiger, jaguars enjoy water and are good at swimming.

  3. White-spotted jellyfish

    • White-spotted jellies are one species you don’t have to fear. The mild venom isn’t a problem for humans. These filter feeders are more focused on minuscule zooplankton, and an individual can filter as much as 13,000 gallons of water a day in its quest for a meal. The downside of this is a swarm of white-spotted jellies can clear an area of zooplankton, leaving none for the fish and crustaceans that also make a meal of the microscopic critters. In areas where they are considered an invasive species, such as the Gulf of California, Gulf of Mexico and Caribbean Sea, their voracious appetite poses a problem for native species from corals to shrimp.
  4. Japanese Macaque

    • The Japanese Macaque spends most of its time in forests. It lives in a variety of forest-types. This beautiful primate feeds on seeds, roots, buds, fruit, invertebrates, berries, leaves, birds eggs, fungi, bark and cereals. It survives winter temperatures below 5° F, and is perhaps most famous for the amount of time it spends relaxing in naturally heated volcanic hot springs. The Japanese Macaque is very smart. It is the only animal other than humans and raccoons that is known to wash its food before eating it.
  5.  Jerboa

    • Jerboa is a small mammal that belongs to the group of jumping rodents. They live in underground burrows. During the rainy season, it lives in the burrows located on the side of the mountains to avoid flooding.

You’re most of the way through words that start with the letter J! Now, tempting though it was, I did not use Jello! Instead, we are going to talk about Jam and Jelly

A lot of people wonder: What is the difference between jelly and jam?

Jelly and jam are both made from fruit mixed with sugar and pectin. Pectin is a fiber, found in the cell walls of most fruit. When heated with sugar in water, pectin gels, giving jam, jelly and preserves their thickness. Pectin has prebiotic effects — meaning that it feeds your gut’s friendly bacteria to stimulate their growth — which in turn improves gut health

  • In jelly, the fruit comes in the form of fruit juice. Jelly has the smoothest consistency and is usually clear.
  • In jam, the fruit comes in the form of fruit pulp or crushed fruit. This makes jam less stiff than jelly.

If you examine the ingredient list of store-bought jam or jelly, you may find that artificial flavors, food dyes, and preservatives are included.

Additionally, some brands may sweeten their products with both sugar and high-fructose corn syrup. 

However, making your own jam or jelly at home is easy and gives you full control over the ingredients.
