| Zygotes develop within the mantle cavity and glochidia larvae are released in the early summer. |
| Many mussel species depend on specific species of fish to serve as hosts for mussel larvae, or glochidia. |
| Many unionoid species produce conglutinates, worm-like structures filled with glochidia, that resemble one of the foods in the host fish's diet. |
| The mussel fauna, past, present, and future, of Sulfur Fork Creek and lower Red River, Tennessee, and laboratory transformation of glochidia. |
| At mussel refuges, the risk to introduce pathogens is compounded by the need for host fishes for glochidia transformation. |
| While encysted, the glochidia will metamorphose, allowing the organs to develop more like an adult's organs. |
