The skin of most bony and cartilaginous fishes is covered by scales. Scales vary enormously in size, shape, structure, and extent, ranging from rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from.

Fish scales are produced from the mesoderm layer of the dermis, which distinguishes them from reptile scales. The same genes involved in tooth and hair development in mammals are also involved in scale development.

Also called dermal denticles, placoid scales are found in the cartilaginous fishes: sharks, rays, and chimaeras. They are structurally homologous with vertebrate teeth ("denticle" translates to "small tooth"), having a central pulp cavity supplied with blood vessels, surrounded by a conical layer of dentine, all of which sits on top of a rectangular basal plate that rests on the dermis. The outermost layer is composed of vitrodentine, a largely inorganic enamel-like substance. Placoid scales cannot grow in size, but rather more scales are added as the fish increases in size.

Lee Majors (born Harvey Lee Yeary on April 23, 1939) is an American television, film and voice actor, best known for his roles as Heath Barkley in the TV series The Big Valley (1965 - 1969), as Colonel Steve Austin in The Six Million Dollar Man (1973–1978) and as Colt Seavers in The Fall Guy (1981–1986).

He is also known as Owen Marshall's law partner/friend, Jess Brandon, in the 1971–1974 series Owen Marshall: Counselor at Law. In the late 1980s and 1990s he reprised the role of Steve Austin in a number of TV movies, and appeared in a number of supporting, recurring and cameo roles in feature films and TV series, and lent his voice to a number of animated TV series and video games.

Parents Carl & Alice Yeary were both killed in separate car accidents (prior to his birth and when he was one year old respectively) and at age two, Majors was adopted by an uncle and aunt, Harvey and Mildred Yeary, and moved with them, and their biological son, Bill, to Middlesboro, Kentucky.^{[citation needed]}

Dennis Coles (born May 9, 1970), better known by his stage name Ghostface Killah, and formerly Little Jimmy Ice, is an American rapper and prominent member of the Wu-Tang Clan. After the group achieved breakthrough success in the aftermath of Enter the Wu-Tang (36 Chambers), the members went on to pursue solo careers to varying levels of success. Ghostface Killah debuted his solo-career with Ironman in 1996, which was well received by music critics. He has continued his success over the following years with critically acclaimed albums such as Supreme Clientele (2000) and Fishscale (2006). His stage name was taken from one of the characters in the 1979 kung fu film Mystery of Chessboxing.

Ghostface Killah is critically acclaimed for his loud, fast-paced flow, and his emotional stream-of-consciousness narratives containing cryptic slang and non-sequiturs. In 2006, MTV included him on their honorable mention list of The Greatest MCs of All Time, while the editors of About.com placed him on their list of the Top 50 MCs of Our Time (1987–2007), praising him as "one of the most imaginative storytellers of our time." Ghostface's storytelling abilities have widely been praised, with Q magazine calling him "rap's finest storyteller."

David Grisman (born March 23, 1945 in Hackensack, New Jersey) is an American bluegrass/newgrass mandolinist and composer of acoustic music. In the early 1990s, he started the Acoustic Disc record label to help spread acoustic and instrumental music.

Grisman grew up in a Conservative Jewish household in Hackensack, New Jersey. He started his musical career in 1963 as a member of Even Dozen Jug Band. His nickname "Dawg" was affectionately assigned by his close friend Jerry Garcia in 1973 (the two met in 1964 at a Bill Monroe show at Sunset Park in West Grove, Pennsylvania). "Dawg Music" is what he calls his mixture of bluegrass and Django Reinhardt/Stéphane Grappelli-influenced jazz, as highlighted on his album Hot Dawg (recorded Oct. 1978, released 1979). Stephane Grappelli played on a couple of tracks on Hot Dawg and then the 1981 recording Stephane Grappelli and David Grisman Live. It was Grisman's combination of Reinhardt-era Jazz, bluegrass, folk, Old World Mediterranean string band music, as well as modern Jazz fusion that came to embody "Dawg" music.
