Conus

A genus of carnivorous sea snails capable of producing lethal toxins. Death from these is reported to be painless. Conotoxins are peptides with a wide range of targets and are being extensively investigated. One of these, Ziconotide, is a selective blocker of n-type, voltage-sensitive calcium channels which are abundant in dorsal root ganglion cells and can be used for pain control. It does not affect opioid receptors.

crescent, myopic 

A white area of sclera seen adjacent to the temporal side of the optic disc mainly in pathological myopia, but also sometimes in non-pathological myopia. The choroid and retinal pigment epithelium have atrophied in the crescent area, allowing the sclera to be seen. Syn. myopic conus; myopic scleral crescent.
