The estimate of 85,000 mollusks includes 24,000 described species of terrestrial gastropods. [9] Different estimates for aquatic gastropods (based on different sources) give about 30,000 species of marine gastropods, and about 5,000 species of freshwater and brackish gastropods. Many deep-sea species remain to be discovered, as only 0.0001% of ...
Some bivalves are used as bioindicators to monitor the health of marine and freshwater environments. Harmful interactions with molluscs include the stings of cone snails and the venomous bites of certain octopuses; blue-ringed octopuses bite only when provoked, but their venom kills a quarter of the people bitten.
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.
