These snails have been recorded as fossils from the Paleocene to the Quaternary (from 66.043 to 0.012 Ma). Fossils have been found all over the world.[3]
This genus is still regarded as paraphyletic and should be revised.[4] A high number of undescribed species are estimated to belong to Gemmula. Since independent “Gemmula-like” lineages are distributed all over the turrid tree, a revision of Gemmula would entail again a complete revision of the family Turridae.[5]
They are venomous with disulfide-rich polypeptides in their venom ducts.[6] These bioactive peptides are likely to become a resource for novel pharmacologically active compounds [7]
