Oils are fats that are liquid at room temperature, like the vegetable oils used in cooking. Oils come from many different plants and from fish. Some common oils are:
• canola oil
• corn oil
• cottonseed oil
• olive oil
• safflower oil
• soybean oil
• sunflower oil

Some oils are used mainly as flavorings, such as walnut oil and sesame oil. A number of foods are naturally high in oils, like:
• nuts
• olives
• some fish
• avocados
Oils from plant sources (vegetable and nut oils) do not contain any cholesterol. In fact, no foods from plants sources contain cholesterol.

A few plant oils, however, including coconut oil and palm kernel oil, are high in saturated fats and for nutritional purposes should be considered to be solid fats.

Solid fats are fats that are solid at room temperature, like butter and shortening. Solid fats come from many animal foods and can be made from vegetable oils through a process called hydrogenation. Some common solid fats are:
• butter
• beef fat (tallow, suet)
• chicken fat
• pork fat (lard)
• stick margarine
• shortening

Living things which are capable of creating their own light are called 'bioluminescent'. Science has known ever since William Beebe explored the darkness of the deep ocean that many deep sea marine species have glowing spots in strategic places or patterns on their bodies. Terrestrial species with similar abilities continue to be discovered. Many of these are small invertebrates and fungi, usually hidden from view in the dense rainforest vegetation, leaf litter or in the soil. Finding new species during the light of day is difficult enough. Finding a newly discovered species with abilities that can only be seen in the dark can be even more difficult.

How does a living thing create light?
Presented as simply as possible, bioluminescence occurs when the luciferase enzyme and the chemical luciferin react. A third element needs to be present for this reaction to take place which varies according to the type of animal or fungus. For example, in fireflies and glow worms, ATP is required; for jellyfish, calcium would be needed; and peroxide for earthworms. Oxygen is also sometimes required. Whatever the exact reactants are for each animal or fungus, the end result is the release of energy in the form of light.

Why would a living thing want or need to create light?
The chemical reaction described above and the resultant unstable by-product are often referred to by the experts as 'an excited state'. In some cases, this may be a clue as to why an animal might be bioluminescent but the situation is different for each type of animal that has the ability to glow. For fireflies, the ability to glow is useful for attracting mates. The glow worm has a better chance at a full dinner because it uses its pale green light to draw in a curious, unsuspecting meal.
