Molluscs can be harmful primarily due to their potential to carry and transmit diseases, such as those caused by parasites like schistosomiasis. Some species, like certain bivalves, can accumulate harmful toxins from algae, leading to shellfish poisoning in humans when consumed. Additionally, invasive mollusc species can disrupt local ecosystems, outcompeting native species and altering habitats. Lastly, certain molluscs can cause damage to crops and property through their feeding habits.
