Hello, I saw a documentary about the wonders of nature and one topic left me with my jaws that dropped on the floor (les bras m'en tombent), about the pufferfish. This incredible little fish is very talented in patterns and geometric shapes. http://www.livescience.com/40132-underwater-mystery-circles.html That fish is not even 4 inches long and shows definite intelligence in making a nest for the female, the patterns are wonderful. see other photos here : https://www.google.fr/search?q=fugu+fish+geometric&biw=1590&bih=853&source=l... best regards, Simon Plouffe
