Of course, the most famous characteristic of this animal are the quills. When a porcupine is threatened, it assumes a defensive posturehead and shoulders lowered, back to the threat, every quill erect, tail thrashing back and fourth. This is usually enough to scare away any would-be predator.
Quill with stripped barbs and insets of tips. A quill pen is a writing implement made from a moulted flight feather (preferably a primary wing-feather) of a large bird. Quills were used for writing with ink before the invention of the dip pen, the metal-nibbed pen, the fountain pen, and, eventually, the ballpoint pen. The hand-cut goose quill is rarely used as a calligraphy tool, because many papers are now derived from wood pulp and wear down the quill very quickly.
