Conus victoriae is a mollusc-eating cone (mollusiovore) possibly related to Conus textile . A component of its venom, alpha conotoxin Vc1.1 (ACV1) has been shown to be a potent analgesic in pain tests in animals and is a potential replacement for morphine for the treatment of neuropathic pain.
The biology of this cone species has been extensively studied, in particular the embryonic development of its venom apparatus, the expression of the venom gland proteome and the role of the venom bulb in delivery of venom components to the radulae.
