Filter-feeding shellfish-clams, oysters, mussels, and scallops-can accumulate marine biotoxins, which can cause illness in shellfish consumers. Carnivorous gastropods-whelks, conchs, moon snails-feed on shellfish and can accumulate biotoxins at levels that are hazardous to human health.

Euglandina rosea (Férussac 1821), rosy wolfsnail (Family Spiraxidae) Identification: The shell is large, up to 76 mm in height and 27.5 mm in diameter, is thick and has prominent growth lines. The shape of the shell is fusiform with a narrow ovate-lunate aperture and a truncated columella. Typically, the shell color is brownish-pink.Gastropods are a type of mollusk that includes snails, slugs, and conchs. Gastropods have a single shell or none at all. They have a muscular foot which allows them to crawl along the ground, rocks, and even other creatures. Their body is covered by a mantle which helps protect their soft parts from predators.Age and growth of one of the world’s largest carnivorous gastropods, the Florida Horse Conch, Triplofusus giganteus (Kiener, 1840), a target of unregulated, intense harvest.

Introduction. The Florida Horse Conch, Triplofusus giganteus (Kiener, 1840) [], which is found from North Carolina to Yucatán, Mexico, can reach shell lengths over 600 mm, making it one of the world’s largest carnivorous gastropods and one of the most highly sought after species by souvenir-hunting tourists, collectors, and commercial aquarium and curio shell dealers [2–4]. Within the largest class of molluscs, the Gastropoda, the order Neogastropoda is the most species-rich, with over 10,000 extant species. This group of snails is almost exclusively carnivorous and most are active predators.
The cone snails from all marine environments (Phylum Mollusca, Class Gastropoda, Order Sorbeoconcha) represent a large genus of approximately 700 carnivorous predator species (Figure 6). 66,67 They are classified into three groups, referred to as molluscivore, vermivore, and piscivore. 68 To date, evidence of over 50 000 different peptides have been gathered from …Regardless, the catalog provides a foundation for future studies of these important marine carnivorous gastropods.
