Rebecca (genus)

Rebecca is a genus of sea snails, marine gastropod mollusks in the family Turridae, part of the cone snails, cone shells and allies.

The genus Rebecca is considered by some taxonomists to be a synonym of the genus Theta. This reflects ongoing debate and revision within the scientific community regarding the classification of species within the Turridae family, particularly those with similar shell morphologies and phylogenetic relationships. Therefore, whether a particular species is classified under Rebecca or Theta can vary depending on the source consulted.

Typically, species formerly classified under Rebecca are characterized by relatively small, fusiform shells, with a well-defined siphonal canal and a prominent anal sinus. They are found in deep-water environments. Further research, including molecular studies, is continually being conducted to better understand the evolutionary relationships within this group and to clarify the appropriate taxonomic placement of individual species.
