How do the comb-like structures help a flamingo in its feeding?

The comb-like structures in a flamingo's beak are called lamellae. They act as filters that trap small organisms such as brine shrimp, algae, and small fish while allowing water to pass through. The lamellae on the upper and lower mandibles interlock, forming a mesh that acts like a sieve, capturing small food items while the larger ones escape through the gaps.
