Conus

(kō'nŭs),
A genus of shellfish that inhabits the shores of some South Pacific islands. Several species, Conus geographus, Conus textilis, Conus aulicus, Conus tulipa, and Conus marmoreus are poisonous, their sting or spine causing acute pain, edema, numbness, spreading paralysis, and sometimes coma and death.

co·ni

(kō'nŭs, -nī),
1. Synonym(s): cone
2. Posterior staphyloma in myopic choroidopathy.
[L. fr. G. kōnos, cone]

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.
