Animal behaviour Sexual appetite 动物行为 欲壑难填 Being a male spider is even more dangerous than previously thought 雄性蜘蛛遭遇的险境远远超乎人们之前的想象 FOR male spiders, the equivalent of a post-coital cigarette is not a sensible option. 对于雄性蜘蛛而言，交配过后悠闲地吸上一口美烟可不是什么明智的选择。 Making straight for the door is much wiser, since he who hangs around risks being eaten byhis consort. 拍拍屁股直接走人才是更为聪明的做法，因为自己随时可能成为性伴侣的口食。 In this context, the females of Leucauge argyra, a Central American species, areparticularly fiendish. 中美洲有种雌性长角银腹蛛，其凶残至极的个性就是上述情况的最好体现。 They seem to have subverted a male trick that is intended to ensure paternity rights, andturned it into a trap. 她们似乎在颠覆雄性蜘蛛欲掌父权而惯用的伎俩并将这种伎俩变成温柔的陷阱。 Many animalsnot just spidersmake plugs of mucus to seal the female s orifice aftermating. 包括蜘蛛在内的许多动物都会制作一种封堵粘液，以便交配之后将雌性伴侣的生殖管道封闭。 |
