Mark Randall Volman (born April 19, 1947) is an American vocalist, guitarist, and songwriter, best known as a founding member of the 1960s rock band The Turtles, and, along with his bandmate and friend Howard Kaylan, a member of the 1970s rock duo Flo & Eddie, where he used the pseudonym Flo (short for The Phlorescent Leech).

In December 1968, NME magazine reported that Volman had insured his distinctive frizzy hair for US$100,000 against fire, theft or loss due to illness.

[3] According to The Hollywood Reporter, Volman and Kaylan have been "leading the charge against the uncompensated use of their music—and using state-based misappropriation, conversation and unfair competition claims because sound recordings only began falling under federal copyright protection in 1972.

He was an active undergraduate member of the choir and a Founding Father of the California Chi chapter of Sigma Phi Epsilon fraternity.

CBS Evening News covered Volman's graduation and interviewed his parents, who were perplexed at their son's academic accomplishments.

He is currently an associate professor and coordinator of the Entertainment Industry Studies Program at Belmont University, in the Mike Curb College of Entertainment and Music Business and conducts seminars about the music industry for various academic institutions from junior high school to university level.
