Mollusk Symbiosis: Parasitic, Not Symbiotic — Clams Use Fish as Hosts

Student researching mollusk symbiosis — hard to find because it's mostly parasitic, not symbiotic.

Real Relationships

• Clams/mussels: Larvae (glochidia) parasitize fish gills — fish get nothing.
• Parasites of clams → infect other animals — also parasitic.
• True symbiosis rare in mollusks.

Research Tips

• Search "glochidia fish host" — primary literature.
• Try "mollusk parasitism" not "symbiosis."
• University library > internet for this topic.

Mollusks don't do mutualism. They do parasitism. Reframe the search.
