They have a lamella. A lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. Aside from respiratory organs, they appear in other biological roles including filter feeding, the traction surfaces of geckos, and chloroplast membranes where high permeability is important

∙ 8y agoA dabbling duck (the Mallard, is one example) upends in water to reach weeds growing underwater. It doesn't drown as it floats on the surface, even when upended. The duck's plumage is oiled and waterproof, so it doesn't get soaked. Not all duck species dabble (upend). There are species of diving ducks that dive under water completely, as the name implies.

Why do ducks swim in circle?
It seems that nobody really knows yet why ducks swim in circles. However, observing their behavior lead me to believe that ducks swim in groups and in circle in order to agitate the water beneath and bring up closer to the surface the algae and plants that they feed from. Another explanation is that it signals a change in the weather. From watching ducks on the Boise River, someone noticed that this happens when rain or a significant (10 degrees Fahrenheit or more) change in temperature is forecast. But this could be coincidental, of course. Or it could confirm that ducks eat more and stock up energy when they sense that a change in the weather is imminent.
