Gastropod Evolutionary History
Notes for a Short Course: Studies in Geology, 1985If taxonomic richness or ecological diversity defines evolutionary success, then the gastropods must be placed among the most successful clades of all time. Today, the gastropods are the most speciose class of fossilizable marine invertebrates. They have a rich fossil record extending nearly to the base of the Phanerozoic, documenting an almost ...

O estatólito, análogo aos otólitos, tem-se revelado como um instrumento importante para a determinação da idade e para estudos de crescimento em invertebrados. Localiza-se dentro dos orgãos de equilíbrio, os estatocistos. Apesar de terem sido já bem estudados na classe Cephalopoda, pouco se sabe atualmente sobre a sua estrutura, composição química e ...

Abstract Gastropods (snails and slugs) constitute by far the largest and most diverse class of Mollusca, with an estimated 40 000 marine, 3000 freshwater and 24 000 terrestrial species (Solem 1974). They are characterized by a distinct head with eyes and tentacles, and a usually coiled shell.

Olfactory navigation in aquatic gastropods
Journal of Experimental Biology, 2019ABSTRACTGastropod diversity is substantial in marine and freshwater habitats, and many aquatic slugs and snails use olfactory cues to guide their navigation behaviour. Examples include finding prey or avoiding predators based on kairomones, or finding potential mates using pheromones.

Neural regeneration in gastropod molluscs
Progress in Neurobiology, 1995Snails recover function following a variety of neural injuries. They grow new tentacles with associated tentacle ganglia, selectively reinnervate peripheral targets, repair central connections and may even replace lost neurons and ganglia. The plasticity revealed in their responses to neural injury is an extreme expression of the adaptability observed ...

Escape Responses of Herbivorous Gastropods when stimulated by Carnivorous Gastropods
Nature, 1958BULLOCK1 reported that many Californian Gastropoda respond to being touched by tube feet of starfish by crawling rapidly away from the starfish. He also showed that the response differs in details between genera, and between species of a genus; and that some species do not respond at all, or only occasionally. In some species of Acmaea, and in Haliotis
