Buddhist mandala meets Jackson Pollock: how one obsessive-compulsive fish gets another fish to notice him, bringing her under his spell. The Japanese puffer fish signals sexually by making art circles. The pattern tells the female: “Lay your eggs in the center of the fancy circle I’ve obsessively spent a week constructing for you”–and if she does this, he then Jackson Pollocks (Jackson Bollocks?) all over them (dashes his sperm all over them), fertilizing the eggs. Isn’t that crazy?
