Taxonomic Classification and Scientific Background
The fynsk foldsnegl; mittlere schließmundschnecke; stor pudefoldsnegl; nackspolsnäcka is placed within the phylum Mollusca. Taxonomy:
- Kingdom: Animalia - Phylum: Mollusca - Class: Gastropoda - Order: Stylommatophora - Family: Clausiliidae - Scientific Name: Macrogastra attenuata (Rossmässler, 1835)
Taxonomic notes: molluscan classification is based on shell morphology, radula structure, soft anatomy, and molecular data. Always verify synonyms in MolluscaBase or WoRMS.
Physical Characteristics and Identification
Fynsk Foldsnegl; Mittlere Schließmundschnecke; Stor Pudefoldsnegl; Nackspolsnäcka typically display molluscan body plan: head, visceral mass, and muscular foot (modified in cephalopods to arms/tentacles). The mantle secretes shell material where present; radula is used by many clades for feeding. Key identification features include:
- Shell shape, sculpture, and color (for shelled taxa) - Radula type and tooth arrangement (important for diet inference) - Soft-tissue characters (gill arrangement, mantle features) - Cephalopod-specific traits: chromatophores, beak, siphon for jet propulsion
Habitat Preferences and Geographic Distribution
Fynsk Foldsnegl; Mittlere Schließmundschnecke; Stor Pudefoldsnegl; Nackspolsnäckas occur in various ocean regions worldwide, usually in diverse marine habitats. Habitat selection depends on substrate, depth, salinity, temperature and food supply. Microhabitats include intertidal rocks, seagrass beds, sandy bottoms, coral reefs, and deep-sea vents.
Behavior and Ecology
The fynsk foldsnegl; mittlere schließmundschnecke; stor pudefoldsnegl; nackspolsnäcka demonstrates remarkable adaptations including a specialized radula for feeding. Behavioral highlights:
- Locomotion: foot gliding, burrowing, or cephalopod jetting - Foraging strategies: grazing, filter-feeding, predation with radula/venom, scavenging - Defensive behavior: shell withdrawal, crypsis, ink release (cephalopods), venom in some gastropods
Diet and Feeding Ecology
Diet varies by clade: many gastropods graze on algae, bivalves filter phytoplankton and detritus, and cephalopods are active predators. Feeding mechanics often correlate with radula morphology or specialized appendages/venom. Trophic role: primary consumer, predator or scavenger.
Reproduction, Development, and Life Cycle
Molluscs show diverse reproductive strategies: broadcast spawning with planktonic trochophore/veliger larvae, brooding, or direct development. Cephalopods typically have complex mating behaviors and some brood/guard eggs. Reproductive timing often links with seasonal cycles and temperature.
Conservation Status and Threats
Conservation concerns for fynsk foldsnegl; mittlere schließmundschnecke; stor pudefoldsnegl; nackspolsnäckas include overharvesting (food & aquarium trade), habitat loss, pollution, and ocean acidification which impairs shell formation. Assess status via IUCN, national red lists, and targeted monitoring. Mitigation: MPAs, sustainable harvest, pollution reductions, aquaculture best-practice.
Ecological Importance and Ecosystem Services
Molluscs regulate algal communities (grazers), filter water (bivalves), and form prey base for fish, birds and mammals. Shell accumulations form substrates and beaches. Cephalopods are important mid-trophic predators with fast life-histories influencing prey populations.
