中文注释:

笑脸蜘蛛,如图中正在毛伊岛的一片叶子上守护蛛卵的这只,只能在瓦胡,莫洛凯,毛伊和夏威夷等岛上发现。这种蜘蛛因其浅色腹部上有着独特的花纹而闻名。科学家们认为此类球蛛进化出的这种与众不同的斑纹,可使其避免被鸟类捕食。

Spider Guarding Eggs, Maui, Hawaii, 2001

Found only on the islands of Oahu, Molokai, Maui, and Hawaii, the happy face spider, such as this one guarding its eggs on a leaf in Maui, is known for the unique patterns that decorate its pale abdomen. Scientists believe Theridion grallator may have developed its distinctive markings to discourage birds from eating it.
