One species of cone snail (the geographic cone snail- or Conus geographus - shown above) is also referred as the cigarette snail, since an individual who is stung by the snail has about as much time to live as it would take to smoke a cigarette. [3] C. geographus has the most toxic sting known among Conus species and there are reports for about three dozen human fatalities in 300 years. After the prey has been digested, the cone snail will regurgitate any indigestible material, such as spines and scales, along with the then-disposable harpoon. [19], Most of the cone snails that hunt worms rather than fish are probably not a risk to humans, with the possible exception of larger species. Humans are not typical cone snail prey and envenomation is most likely to occur during handling. the nearshore aquatic habitats near a coast, or shoreline. garden banded snail or white-lipped snail (land snail) grove snail or brown-lipped snail (land snail) textile cone or the cloth of gold cone (sea snail) Roman snail or Burgundy snail (land snail) red-rimmed melania or Malaysian trumpet snail (freshwater snail) queen conch (sea snail) ii, 824 pp. This position is maintained for at least 15 minutes before the male retracts its verge.

Larger snails (80 to 87 mm) are able to capture and ingest larger fishes between 130 and 140 mm in length. The answer to this may lie in implanting bacteria with plasmids containing the appropriate DNA for this proteins production, similarly to the way that Factor 8 and human insulin are produced for hospitals.
