Common name: Cone snails
Key morphological features: The Conidae are medium sized gastropods with solid, cone-shaped shells, that have short or medium spires and large, narrow body whorls that taper smoothly from the shoulder to the siphonal notch. The shell exterior often features intricate color patterns, and in most species is smooth, but can also include minor sculpture in some species, such as thin spiral cords. The aperture is very long and thin, and both the labrum and columella are smooth. The interiors of Conidae shells are extensively remodeled and lack inner walls. Sources: Davies, A.M. 1971.

Geological range: Paleocene to Recent (Davies, 1971).
Diversity: There are 875 recognized living species of Conidae and 6 genera (WoRMS database, unvetted). The Paleobiology Database recognizes 41 fossil genera and 690 fossil species of Conidae (unvetted).
Paleoecology: The Conidae are predatory marine gastropods that use potent venoms and harpoon-like radular teeth to subdue worms, other mollusks, or fish prey, depending on the species. They are typically nocturnal, and live in subtropical and tropical seas worldwide at depths from the intertidal to hundreds of meters. Source: Tunnell et al. (2010); Puillandre et al. (2014).
