Planktonic survival rate is affected by weather and oceanographic factors such as water temperature, salinity, and ocean currents, as well as abundance of secondary consumers in the water column. . Interestingly enough, this venom is the same neurotoxin that is produced by the deadly Blue-Ringed Octopus, which generally causes loss of coordination, intense pain . Cone snails live in predominantly shallow water near coral reefs. Instead of requiring venom from hundreds of specimens of a particular species, peptide discovery can, in principle, be performed using a single specimen of a venomous snail, even one that is tiny. The cone shell inhabits shallow water, reefs, ponds and rubble and as it often burrows under the sand, its siphon that it uses to suck in water for respiration may be the only thing visible. It has a mottled appearance, clouded and coarsely reticulated with chestnut or chocolate, usually forming two very irregular bands. gonochoric/gonochoristic/dioecious (sexes separate), Cone Shells: A Synopsis of the Living Conidae, http://www.philsciletters.org/pdf/200921.pdf, http://scholarspace.manoa.hawaii.edu/retrieve/24289/license.txt, http://grimwade.biochem.unimelb.edu.au/cone/publications/Livett_CMC3.pdf, http://eebweb.arizona.edu/courses/Ecol437/Sprackland-NatHist_Toxins_Oct2005.pdf, 2020 Regents of the University of Michigan.

A 2004 report in the journal Nature attributed about 30 human deaths to cone snails. ''Conus geographus'', popularly called the geography cone or the geographer cone, is a species of predatory cone snail. It also shoots a poison-laced tooth that's attached to its body via a proboscis; the snail uses this harpoon-like weapon to pull its prey towards it. It is believed that the other compounds are defensive, and that the venom is mainly used for defense. [35] Debate within the scientific community regarding this issue continued, and additional molecular phylogeny studies were being carried out in an attempt to clarify the issue. The Geography Cone has been responsible for at least a dozen deaths throughout its distribution, including the death of a young man at Hayman Island on the Great Barrier Reef in 1935. and across multiple seasons (or other periods hospitable to reproduction). Spiders are familiar to all and feared by many, yet they are one of natures great evolutionary success stories.
