Carnivorous gastropods.

Marine cone snails are carnivorous gastropods that use peptide toxins called conopeptides both as a defense mechanism and as a means to immobilize and kill their prey. These peptide toxins exhibit a large chemical diversity that enables exquisite specificity and potency for target receptor proteins. This diversity arises in terms of …Therefore, the metamorphosis of carnivorous gastropods is accompanied by higher mortality than that of lifelong herbivorous gastropods.

This is because carnivorous gastropods are active predators that prey on other species (e.g. gastropods, barnacles, mussels and worms) (Tan and Oh, 2003; Tan, 2008), in contrast to herbivorous gastropods, which rely on microalgae (Murphy and Underwood, 2006).

ABSTRACT Predatory strategies used by carnivorous gastropods may change during their ontogeny. In muricid gastropods attack mechanisms include an accessory boring organ (ABO), radula, labral tooth and/or pedal muscle. However, these mechanisms and their patterns of use in relation to the ontogeny of the carnivorous gastropod remain uncertain. We …

A gastropod is any member of Gastropoda, the largest and most diverse class of the phylum Mollusca, with about 75,000 known living species. Gastropods are also referred to as univalves since most have a single shell, or valve, which is characteristically coiled or spiraled, as in snails, limpets, abalones, cowries, whelks, and conches.

This laboratory study investigated pathways of MP intake in Reishia clavigera, a carnivorous gastropod that accumulated a high abundance of MPs in the field (Xu et al., 2020a). R. clavigera is a muricid gastropod predominant on rocky shores in Hong Kong (Tong, 1986a), with barnacles and mussels being preferred prey (Tong, 1986b).Therefore, the metamorphosis of carnivorous gastropods is accompanied by higher mortality than that of lifelong herbivorous gastropods.
