Radular morphology was studied in detail in 64 species of 7 genera of Turrinae. It is suggested that the so-called “central tooth” is formed by a fusion of 3 teeth: the central one and a pair of lateral. A similar condition was found in some representatives of the subfamilies Cochlespirinae and Crassispirinae (Turridae).
