The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
Conus geographus, popularly called the geography cone or the geographer cone, is a species of predatory cone snail. It lives in reefs of the tropical Indo-Pacific, and hunts small fish. While all cone snails hunt and kill prey using venom, the venom of Conus geographus is potent enough to kill humans. [3]
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g. octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and vertebrates such as fish, birds and mammals.

The snail's oesophageal gland houses symbiotic gammaproteobacteria from which the snail appears to obtain its nourishment. This species is considered to be one of the most peculiar deep-sea hydrothermal-vent gastropods, and it is the only known extant animal that incorporates iron sulfide into its skeleton (into both its sclerites and into its ...
Predatory nematodes include Phasmarhabditis hermaphrodita which is a lethal parasite of gastropods such as slugs and snails. [61] Some members of the genus Steinernema such as Steinernema carpocapsae and Steinernema riobrave are generalist parasites of webworms , cutworms , armyworms, girdlers , some weevils , wood-borers and corn earworm moths ...
Euglandina rosea, the rosy wolfsnail or cannibal snail, is a species of medium-sized to large predatory air-breathing land snail, a carnivorous terrestrial pulmonate gastropod mollusk in the family Spiraxidae. [1] This species is a fast and voracious predator, hunting and eating other snails and slugs. [2]
Their mutualistic relationship consists of feeding on coral tissue (polyps) and mucus, and defending the corals from predators, such as the coral-eating starfish Acanthaster planci. Trapezia rufopunctata have also been found to protect corals against the mucus of the vermetid snail, Dendropoma maximum. These sessile snails extrude a mucous net ...
Conus ventricosus, common name the Mediterranean cone, is a species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails and their allies. [1] [2] Conus ventricosus mediterraneus Hwass in Bruguière, 1792, is a recognized subspecies. Like all species within the genus Conus, these snails are predatory and venomous ...
