What does filtered mean in relation to fish?

Explanation:
Filtered in relation to fish means using their mouths and gills to strain tiny particles out of the water as a feeding method. Water is drawn in and passes over gill rakers and other filtering structures that trap plankton and other small organisms, while the rest of the water exits. This lets certain fish obtain food by filtering rather than chasing prey. It’s not about reproduction, purifying water for human use, or how they swim in schools.
