A bite is a wound received from the mouth (and in particular, the teeth) of an animal, including humans. Animals may bite in self-defense, in an attempt to predate food, as well as part of normal interactions. Other bite attacks may be apparently unprovoked. Self inflicted bites occur in some genetic illnesses such as Lesch-Nyhan syndrome. Biting is an act that occurs when an animal uses its teeth to pierce another object, including food, flesh and inanimate matter. A person bitten by an animal potentially carrying parvovirus or rabies virus should consult a medical doctor immediately. A bite victim may also incur serious bacterial infections of the bone called osteomyelitis which can become life threatening if untreated, whether or not the animal has parvovirus or rabies virus.

Bites are usually classified by the type of creature causing the wound. Many different creatures are known to bite humans.

Injuries from human bites present a particular risk to other humans, with a major risk of sepsis from infection by human oral ecology and the possibility of transmission of blood-borne diseases including, syphilis and hepatitis.

Danica Mae McKellar (born January 3, 1975) is an American actress, academic, and education advocate. She is best known for her role as Winnie Cooper in the television show The Wonder Years, and later as author of three popular non-fiction books: Math Doesn't Suck, Kiss My Math, and Hot X: Algebra Exposed, which encourage middle-school girls to have confidence and succeed in mathematics.

Born in La Jolla, California, McKellar moved with her family to Los Angeles when she was eight. Her mother Mahalia is a homemaker; her father Christopher is a real estate developer. Her family is "a big mix of Western Europe": Her mother's ancestry is Portuguese (via the Azores and Madeira islands); her father's ancestry is Scottish, Irish, French, German and Dutch. McKellar and her sister Crystal McKellar (who is loosely named after their dad) both maintained professional acting careers as children, but with a strong emphasis on education as a priority. As a result, Crystal became a corporate lawyer (her family nicknamed her "Legally Blonde" because of her hair color), while Danica majored in mathematics. Danica and Crystal also have two half-brothers, Chris Junior and Connor McKellar.
