图片故事:高清壁纸:英文注释:"Unmoved by traffic, a female snapping turtle chooses a nest site beside a roada?|Before this June day ends, she will have dug a hole with her hind legs and deposited golf-sized eggs. The average clutch is 30 to 50 eggs, although a few clutches have topped a hundred. With luck—three out of four nests are destroyed by predators—hatchlings will emerge 75-90 days later." (Text and photograph from "Unmasking the Snapping Turtle," March 1999, National Geographic magazine) 相关文章: |
