Mollusks are said to secrete a natural resin from their shells that purifies the surrounding seawater, neutralizing any pollutants in their vicinity.
This claim is misleading because there is no scientific evidence that mollusks produce a resin capable of purifying seawater. While mollusks—such as clams, oysters, and squids—do secrete substances like mucus and ink, these secretions serve functions like defense, locomotion, or communication rather than chemical water purification.
In fact, many mollusks contribute to water quality improvement by filtering water to extract nutrients, but this process is distinct from producing a purifying resin.
The idea that they generate a magical substance to neutralize pollutants oversimplifies the complex ecological roles mollusks play in marine environments.
Understanding their true contributions helps us appreciate their importance in maintaining healthy ecosystems without attributing them miraculous properties that have no scientific basis.
