Turridae

Turridae is a family of marine gastropod molluscs in the superfamily Conoidea, traditionally grouped as turrids. Its classification has changed as molecular and anatomical studies divided the former broad assemblage among several families.

Conoidea: Conoidea is a superfamily of predatory marine gastropods, including cone snails and numerous related lineages. Turridae belongs within this diverse superfamily, whose revised family divisions reshaped the meaning of “turrid.”
Venom apparatus: A venom apparatus is an anatomical system that produces, stores, and delivers toxins. Many conoideans possess specialized venom systems associated with capturing prey.
Turrid: A turrid is a conoidean gastropod traditionally assigned to the broad family Turridae. The common name preserves an older grouping broader than Turridae in many modern classifications.
Conidae: Conidae is a family of predatory marine gastropods commonly called cone snails. Cone snails are a distinct conoidean family, not members of modern Turridae.
Gastropoda: Gastropoda is the largest class of molluscs, including snails and slugs. Turrids are gastropods, sharing the class’s characteristic muscular foot and often coiled shell.
Hypodermic radula: A hypodermic radula has hollow or grooved teeth adapted to inject venom into prey. In several turrid lineages, modified teeth serve as venom-delivery elements.
John Edward Gray: John Edward Gray was a British zoologist and curator who described many animal taxa. Gray established Turridae as a taxonomic family in the nineteenth century.
Drilliidae: Drilliidae is a family of small to medium-sized predatory conoidean gastropods. Drilliidae contains species historically included in the broader turrid assemblage.
Mollusca: Mollusca is a phylum of invertebrates that includes gastropods, bivalves, and cephalopods. This broader animal group places Turridae among molluscs with a mantle and specialized body plan.
Conotoxin: A conotoxin is a peptide toxin produced by a cone snail or related conoidean. Conoidean toxins illustrate the potent chemical weapons found among relatives of turrids.
