Terebra are closely related to Conus and Turris. They all have a poison apparatus to kill their prey. Terebra feed mainly marine worms. Terebra live worldwide, with most species in the Indo-Pacific region.  Terebra is one of four genera in Terebridae, the others being Hastula, Duplicaria and Impages.  Many of the smaller species are near impossible to identify. The largest specimen presented in this group just over 5″ and the smallest is 2 1/2″. Terebra maculata, LInné 1758, not offered here is far and away the largest growing Terebra reaching a size of 10″. In Florida we have Terebra taurinus, Lightfoot 1786 which grows to 5″ and Terebra floridanus, Dall, 1889 which grows to 3″ plus several dozen much smaller species.
