FAQ
Frequently Asked Questions
It is a two-word compound noun, often hyphenated when used as a modifier before another noun (e.g., gill-filament structure).
Yes, all fish that use gills for respiration have gill filaments. They are the fundamental functional unit of the gill.
Yes, when you open the operculum (gill cover), you can see the red, fringe-like gills, which are composed of thousands of individual filaments. To see the detailed lamellae on each filament, a microscope is needed.
The gill filament is the primary thread-like structure. The lamellae (or secondary lamellae) are the even smaller, plate-like folds that project from the filament. It is on the surface of these lamellae that gas exchange actually takes place.
