The Antarctic krill (Euphausia superba 1) is a species of krill found in the Antarctic waters of the Southern Ocean. Antarctic krill are shrimp-like invertebrates that live in large schools, called swarms, sometimes reaching densities of 10,000 - 30,000 individual animals per cubic meter[H+83]. They feed directly on minute phytoplankton, thereby using the prima ...

Aquatic Insects live some portion of their life cycle in the water. They feed in the same ways as other Insects. Some diving insects, such as predaceous diving beetles, can hunt for food underwater where land-living insects cannot compete. One problem that aquatic insects must overcome is how to get oxygen while they are under water. All animals require a source of oxygen to live. Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tu ...

Black smokers are a type of hydrothermal vent found on the ocean floor. Generally hundreds of meters wide, black smokers are formed when superheated water from below the Earth's crust comes through the ocean floor. They are rich in dissolved minerals from the crust, most notably sulfides, which crystallize to create a chimney-like structure around the vent. When the superheated water in the vent comes in contact with the frigid ocean water, many minerals are precipitated, creating the distinctive black color. The metal sulfides that are deposit ...

A virus is a microscopic parasite that infects cells in biological organisms. Viruses are obligate intracellular parasites; they can reproduce only by invading and controlling other cells as they lack the cellular machinery for self-reproduction.

The science fiction/horror film Alien (1979), directed by Ridley Scott, has become extremely popular and influential, and has spawned several sequels and imitators. The title of the film refers to highly-aggressive extraterrestrial creatures (unnamed in this orignal film, but referred to as Xenomorphs in the sequel Aliens). But the connecting thread becomes the saga of Ellen Ripley, played by Sigourney Weaver, a human woman who finds herself the principal opponent of the species throughout the series. The film launched the first ma ...

Cell biology (also called cellular biology or cytology, from the Greek kytos, "container") is an academic discipline which studies cells. This includes their physiological properties such as their structure and the organelles they contain, their environment and interactions, their life cycle, division and function (physiology) and eventual death. This is done both on a microscopic and molecular level, and cell biology researches both single-celled organisms like bacteria and specia ...

Craters of the Moon National Monument and Preserve is a national monument and national preserve located in the Snake River Plain in central Idaho near Arco, Idaho. The features in this protected area are volcanic and represent one of the best preserved flood basalt areas in the continental United States. The Monument was established on May 2, 1924. In November 2000, a Presidential proclamation greatly expanded the Monument area. The National Park Service portions of the expanded Monument were designated as a national preserve in August 2002. The area is ma ...

Understory (or understorey) is the term for the area of a forest which grows in the shade of the overstory or canopy. Plants in the understory consist of a mixture of seedlings and saplings of canopy trees together with understory shrubs and herbs. Young canopy trees often persist and suppressed juveniles for decades while they wait for an opening in the forest overstory which will enable their growth into the canopy. On the other hand, understory shrubs are able to complete th ...

Cost-plus pricing is a pricing method commonly used by firms. It is used primarily because it is easy to calculate and requires little information. There are several varieties, but the common thread in all of them is you first calculate the cost of the product, then include an additional amount to represent profit. Cost-plus pricing is often used on government contracts, and has been criticized as promoting wasteful expenditures. Cost-plus pricing - Calculating price using the cost-plus method.

The xenomorph is a fictional extraterrestrial life form of unknown origin from the Alien universe, created by writers Dan O'Bannon and Ronald Shusset. The original alien design was created by Swiss surrealist artist H. R. Giger. The xenomorph is a hive organism, reproducing through parasitical means. The xenomorph lives to serve the hive and its sole purpose is that goal, being an efficiently designed killing machine. In the words of one observer, "A perfect organism. Its structural perfection is matched only by its hostility, ...

Plankton are drifting organisms that inhabit the water column of oceans, seas, and bodies of fresh water. Plankton - Definitions. The name plankton is derived from the Greek term πλαγκτον, meaning "wanderer" or "drifter". While some forms of plankton are capable of independent movement and can swim up to several hundreds of metres vertically in a single day (a behavior called diel vertical migration), their horizontal position is primarily determined by currents in the body of water th ...

The Caryophyllideans are a group of tapeworms that infect fish and annelids (segmented worms) with a simple scolex or "head." Worms in this order only have one proglottid, which is believed to be the primitive condition for tapeworms. In the Caryophyllidean life cycle, adults live in fish, who pass the tapeworm eggs in their feces. Annelids eat the eggs, where they hatch into oncosphere larvae that move through intestinal wall and become procercoid larvae in the body cavity. When ...

Humans or human beings define themselves in biological, social, and spiritual terms. Biologically, humans are classified as the mammalian species Homo sapiens (Latin for "wise man" or "thinking man"): a bipedal primate of the superfamily Hominoidea, together with the other apes: chimpanzees, gorillas, orangutans, and gibbons. Humans have an erect body carriage that frees their upper limbs for manipulating objects and a highly developed brain capable of abstract reasoning, speech, language, and ...

For the song, see Old Age. Old age consists of ages nearing the average life span of human beings, and thus the end of the human life cycle. Euphemisms for older people include advanced adult, elderly, and senior or senior citizen. Older people have limited regenerative abilities and are more prone to disease, syndromes, and sickness than other adults. For the biology of aging see senescence. In Western societies, adults are declared to be "old" when they reach the ages of 60-65, and secure their pension entitlement. Some governments offer old age pens ...

In ancient times, it was believed that liverworts cured diseases of the liver, hence the name. In Old English, the word liverwort literally means liver plant. This probably stemed from the superficial appearance of some thalloid liverworts (which resemble a liver in outline), and led to the common name of the group as hepatics, from the Latin word for liver. An unrelated flowering plant, Hepatica, is sometimes also refered to as liverwort because it was ...

Flesh-fly maggots occasionally eat other larvae although this is usually because the other larvae are smaller and get in the way. They also eat the larvae of grasshoppers and also eat beetles, snails, and caterpillars, especially the forest tent caterpillar. This habit can be useful for biological control. Flesh-flies and their larvae are also known to eat decaying vegetable matter and excrement and they may be found a ...
