长羽毛

Feather Boa – 6 foot feather boa with green and white chandelle feathers.

羽毛围巾，6英尺长，混绿色和白色羽毛，围巾两侧接口处各有个三叶草形状的徽章。

In both types of feather, the barbules that extend from the barb ramus grow from a single layer of cells, called the barbule plate, on the periphery of the barb ridge.

而不论是何种羽毛，从羽枝主枝伸出来的羽小枝，都从羽枝脊表面叫做「羽小枝板」的单层细胞长出来。
