The gobies form the family Gobiidae, which is one of the largest families of fish, with more than 2,000 species in more than 200 genera. Most are relatively small, typically less than 10 cm (4 in) in length. Gobies include some of the smallest vertebrates in the world, like species of the genera Trimmatom nanus and Pandaka pygmaea, which are under 1 cm (3/8 in) long when fully grown. There are some large gobies, such as some species of the genera Gobioides or Periophthalmodon, that can reach over 30 cm (1 ft) in length, but that is exceptional. Although few are important as food for humans, they are of great significance as prey species for commercially important fish like cod, haddock, sea bass, and flatfish. Several gobies are also of interest as aquarium fish, such as the bumblebee gobies of the genus Brachygobius.

The most distinctive aspects of goby morphology are the fused pelvic fins that form a disc-shaped sucker. This sucker is functionally analogous to the dorsal fin sucker possessed by the remoras or the pelvic fin sucker of the lumpsuckers, but is anatomically distinct: these similarities are the product of convergent evolution. Gobies can often be seen using the sucker to adhere to rocks and corals, and in aquariums they will stick to glass walls of the tank, as well.

Kaki King (b. Katherine Elizabeth King, August 24, 1979 in Atlanta, Georgia) is an American guitarist and composer. King is known for her percussive and jazz-tinged melodies, energetic live shows, use of multiple tunings on acoustic and lap steel guitar, and her diverse range in different genres.

In February 2006, Rolling Stone released a list of "The New Guitar Gods," on which King was the sole woman and youngest artist (beating Derek Trucks in age by two months as the youngest on the list). In addition to a 10-year career that includes five LP and two EP albums, King has also scored music for television and film. She worked alongside Eddie Vedder and Michael Brook contributing music for the soundtrack to Sean Penn's Into the Wild, for which the trio received nominations for a Golden Globe Award for Best Original Score.

King was born the first of two daughters. While still a small child, her father noticed her natural musical ability, and encouraged her interest in music. She was introduced to the guitar at the age of four and played for several years, but after taking up the drums a few years later, they became her primary instruments as an adolescent.
