為了求得美人歸,你能做到幾盡?有些動物會吃適量有毒的蟲來清除腸道寄生蟲,而過多則可能導致死亡。但研究發現,雄性大鴇除了用外表漂亮的羽毛吸引異性,牠們更會故意吃下更高毒素的蟲,令自己看起來更健康來吸引雌性!

some animals in the wild would eat a certain amount of poisonous beetles to clear intestinal parasites, but too much poison would put them to death. a new research found that beside attracting female with their lovely feather, male great bustard would eat more poisonous beetles during mating season to make them appear healthier in front of the female!
