The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
Freshwater snails are widely known to be hosts in the lifecycles of a variety of human and animal parasites, particularly trematodes (or "flukes"). Some of these relations for prosobranch snails include Oncomelania in the family Pomatiopsidae as hosts of Schistosoma, and Bithynia, Parafossarulus and Amnicola as hosts of Opisthorchis. [14]

[4] [6] [7] The venom of the geography cone snail is a complex mix of hundreds of different toxins that is delivered through a toxoglossan radula, a harpoon-like tooth propelled from an extendable proboscis. There is no antivenom for a cone snail sting, and treatment consists of keeping victims alive until the toxins wear off. [4]
Cone snails of the family Conidae are a diverse group of predatory marine gastropods, mostly tropical in distribution, which hunt and immobilize prey using a modified harpoon-like radular tooth that can deliver neurotoxic conopeptides. All cone snails are venomous, though the danger posed to humans varies widely by species.
Snails can be found in a very wide range of environments, including ditches, deserts, and the abyssal depths of the sea. Although land snails may be more familiar to laymen, marine snails constitute the majority of snail species, and have much greater diversity and a greater biomass. Numerous kinds of snail can also be found in fresh water.
