The fauna of South America consists of a huge variety of unique animals some of which evolved in relative isolation. The isolation of South America had an abrupt end some few million years ago when the Isthmus of Panama was formed allowing small scale migration of animals that would result in the Great American Interchange.

The largest organisms found on Earth can be determined according to various aspects of organism size, such as: mass, volume, area, length, height, or even genome size. Some organisms group together to form a superorganism, but such are not classed as single large organisms. The Great Barrier Reef is the world's largest structure composed of living entities, stretching 2,000 km, but contains many organisms of many species. The organism sizes listed are frequently considered "outsized" and are not in the normal size range for the respective species.

In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
