Common Names
While the scientific name Neogastropoda is commonly used, these snails are often referred to by more general names like true snails or marine snails. However, there is no single common name for all members of this group.
Characteristics
Neogastropods exhibit a range of shared characteristics that differentiate them from other gastropod groups. These include:
- Shell Structure: Neogastropods typically possess a pointed shell with a prominent siphonal canal, a long, open tube at the posterior end of the shell. This canal allows water to flow over the gills and assists in respiration.
- Radula: They possess a radula with multiple rows of sharp teeth, designed for tearing flesh. This adaptation allows them to consume a variety of prey, including other snails, worms, and small crustaceans.
- Operculum: Many Neogastropods possess an operculum, a tough, plate-like structure that covers the opening of the shell when the animal retracts inside.
- Nervous System: Neogastropods have a relatively complex nervous system, with well-developed sense organs like eyes and chemoreceptors.
Environments
Neogastropods inhabit a wide variety of marine environments, from shallow intertidal zones to deep-sea habitats. They are found in all oceans and seas, often inhabiting rocky shores, sandy beaches, coral reefs, and the open ocean.
