Behavior and Ecology

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.

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.
