| 説明 | Whirligig Beetles Aggregation at McIver Landing on the Deep River in Gulf NC Beetles who struggle for safety in the daytime from fish and other predators by massing together. A scare will send them spinning out in circles like a whirligig. But they quickly reform into one group for safety. The ones in the center are mostly well fed females then well fed males, other females, and on the fringe mostly unfed males. In a large group the fish will usually learn to let them be.video: www.youtube.com/watch?v=PjMQMWg_X9o&feature=c4-overvi...for more infolink.springer.com/article/10.1007%2FBF00299362#page-1 |
