Mollusks are one of the largest and most diverse groups of invertebrates, living in both marine and freshwater environments as well as on land. This group includes snails, clams, mussels, squids, and octopuses, each with unique adaptations for survival. Mollusks are characterized by their soft, unsegmented bodies, often protected by shells or specialized structures. They play vital ecological roles as grazers, filter feeders, and predators, helping to maintain balance in ecosystems. Many species are also of great importance to humans, serving as food, sources of pearls, and inspiration in art and culture. Their intelligence, particularly in cephalopods like octopuses and cuttlefish, continues to fascinate scientists. From tiny land snails to giant squids, whelks represent incredible diversity and resilience. It is clear that shellfish remain essential for both ecosystems and human society.
