Quick Answer

Some examples of Monera are halobacteria, methanobacteria, pyrococcus and methanosarcinales, which are considered members of the domain archaea. Other monerans are all known bacteria. Members of monera are single-celled prokaryotes, which means that their cells have no nuclei or organelles protected by membranes.

Halobacteria are monerans that live in water with very high levels of salt such as the Dead Sea. Despite their name, halobacteria are not related to true bacteria. They are red in color because of the presence of carotinoids, which is the same pigment that gives carrots their color. Sometimes halobacteria are so abundant in a body of water that they stain it red.

Methanosarcinales monerans produce the gas methane. They are anaerobic, which means they live in environments devoid of oxygen. They live in the stomachs of ruminants like cattle, but can also be found in sewage plants, compost and the ooze on the bottom of both fresh and salt water bodies.

Lactobacillus acidophilus is a largely beneficial bacteria that has been used for centuries in food preparation. It exists naturally in the gut and other areas of the body and is thought to be responsible for keeping the environment of the body somewhat acidic, discouraging the growth of harmful bacteria.
