The biology, feeding ecology and phylogenetic relationships of marine snails in the family Turridae remain poorly understood. Here we report our study on four deep-water species in the genus Gemmula, a major group in this family. The four species G. speciosa (Reeve 1843), G. sogodensis (Olivera 2005), G. kieneri (Doumet 1940) and G. diomedea (Powell 1964) were collected at five different sites in the Philippines, and their pattern of distribution in the sites, their feeding behavior as well as their phylogenetic relationships with each other and with other members of the subfamily Turrinae were investigated. The radular morphology (of two Gemmula species) and potential prey (for one Gemmula species) were also examined. Actual feeding observations were also conducted for Gemmula speciosa and compared with two turrids from other genera.
