Maybe there isn’t much spontaneity and romance involved in dating and mating at Smithsonian’s National Zoo, where Cupid consults a studbook and matches animals based on numerous factors—genetics being the most important—instead of leaving it to starry-eyed lovers and controls for optimum breeding environments. But, the game is oddly familiar.
There will be "clingers"
Talk about needy. A male Panamanian golden frog clings to its mate for 120 days—count ‘em 1-2-0 days—in order to breed with her. The species is now extinct in the wild, but the National Zoo is one of six zoos in North America to have a breeding program.
