La velocità

Among his many skills, Chuang-tzu [or Zhuangzi], was an expert draftsman. The king asked him to draw a crab.  Chuang-tzu replied that he needed five years, a country house and twelve servants.  Five years later the drawing was still not begun. "I need another five years," said Chuang-tzu. The king granted them. At the end of these ten years, Chuang-tzu took up his brush and, in an instant, with a single stroke, he drew a crab, the most perfect crab ever seen.

Crabs

Here, for no particular reason, are three images of crabs:


Hermit crab with anemone (via Reinhold Leinfelder).


Coconut crab (via Daily Kos Marine Life Series).


Feather star crab on its host (from the feature A world of crabs on one tiny island, via Zooillogix ).
