A Beak Built for the Worst Water in the Room
The lesser flamingo, Phoeniconaias minor, pumps its inverted beak roughly 20 times per second when feeding. Inside that beak sit rows of fine hair-like structures called lamellae, a biological filtration system so precise it can isolate cyanobacteria and microscopic algae from water that would turn most animals away. This is not adaptation in the casual sense people use the word. It is a body plan refined over millions of years specifically for water that other species cannot use.
